4 Resources

The sections below show the MWS resources and the HTTP methods defined on them. The prefix for these resources depends on how the mws.war file is deployed. A typical prefix would be http://localhost:8080/mws. Using this example, one absolute resource URI would be http://localhost:8080/mws/rest/jobs.

This section only contains documentation for the latest API version. Please see the table in the Requesting Specific API Versions section for links to documentation for previous versions.

4.1 Access Control Lists

This section describes behavior of the ACL Rules (Access Control List Rules) object in Moab Web Services. It contains the URLs, request bodies, and responses delivered to and from Moab Web Services.

The ACL API contains the type and description of all fields in the ACL Rules object. It also contains details regarding which fields are valid during PUT and POST actions.

Supported Methods

ACLs are not directly manipulated through a single URL, but with sub-URLs of the other objects such as Virtual Containers and Reservations.

ResourceGETPUTPOSTDELETE
/rest/reservations/rsvId/acl-rules/aclId Create or Update ACLs Delete ACL
/rest/vcs/vcId/acl-rules/aclId Create or Update ACLs Delete ACL

4.1.1 Getting ACLs

Although ACL Rules cannot be retrieved directly using the GET method on any of the acl-rules resources, ACL Rules are attached to supported objects when querying for them. Each supported object contains a field named aclRules, which is a collection of the ACL Rules defined on that object.

Supported Objects

The following is a list of objects that will return ACL Rules when queried:

4.1.2 Creating or Updating ACLs

The HTTP PUT method is used to create or update ACL Rules. The request body can contain one or more ACL Rules. If an ACL Rule with the same type and value exists, then it will be overwritten.

Quick Reference

PUT http://localhost/mws/rest/reservations/<rsvId>/acl-rules
PUT http://localhost/mws/rest/vcs/<vcId>/acl-rules

4.1.2.1 Create or Update ACL

URLs and Parameters

PUT http://localhost/mws/rest/reservations/<objectId>/acl-rules
PUT http://localhost/mws/rest/vcs/<objectId>/acl-rules

ParameterRequiredTypeValid ValuesDescription
objectIdYesString-The unique identifier of the object.

See Global URL Parameters for available URL parameters.

Request Body

The request body below shows all the fields that are available for the PUT method, along with some sample values.

JSON Request Body
{"aclRules": [{
  "affinity": "POSITIVE",
  "comparator": "LEXIGRAPHIC_EQUAL",

    "comparator": "LEXIGRAPHIC_EQUAL",
    "type": "USER",
    "value": "ted"
  }
]}

Restrictions

  • ACL Rules cannot be added to or updated on Standing Reservations.
  • The affinity and comparator fields are ignored for Virtual Containers.

4.1.3 Deleting ACLs

GET http://localhost/mws/rest/diag/auth

URLs and Parameters

GET http://localhost/mws/rest/diag/auth

Sample Response

A successful result is indicated by the 200 response code while a failure is indicated by a 401 response code.

{}

4.4.3 Connection Health Information

The HTTP GET method is used to retrieve health or status information for connections to external systems or software. There are two available resources for health, one that returns simple summary information and another that returns detailed information.

Quick Reference

GET http://localhost/mws/rest/diag/health
GET http://localhost/mws/rest/diag/health/detail

4.4.3.1 Get Health Summary

URLs and Parameters

GET http://localhost/mws/rest/diag/health/summary

If the MongoDB connection is down, authenticated resources are not available. While this resource does not possess much detail beyond that of simple connection information, it is still useful as it does not require authentication and therefore can be used to determine connection problems with MongoDB.

Sample Response

The response contains the connection health for Moab Workload Manager (MWM), Moab Accounting Manager (MAM), and MongoDB. A true response value indicates that the connection is healthy and available, and a false response indicates that the connection is currently down. Likewise, the mongoConnected property for MWM signifies the state of the MWM to MongoDB connection. The possible values of this state are UP, DOWN, NOT_CONFIGURED when the MongoDB server is not configured in MWM, NOT_SUPPORTED when MWM is not compiled with MongoDB support, and UNKNOWN when MWS cannot communicate with MWM.

{
  "mam": {
    "connected": true
  },
  "mongo": {
    "connected": false
  },
  "mwm": {
    "connected": true,
    "mongoConnected": "UP"
  }
}

4.4.3.2 Get Health Detail

URLs and Parameters

GET http://localhost/mws/rest/diag/health/detail

If the MongoDB connection is down, authenticated resources such as this are not available. In this case, using the Get Health Summary instead may be required.

Sample Response

The response contains the connection health and information for Moab Workload Manager (MWM), Moab Accounting Manager (MAM), and MongoDB. A "connected": true response value indicates that the connection is healthy and available, and a false response indicates that the connection is currently down. Likewise, the mongoConnected property for MWM signifies the state of the MWM to MongoDB connection. The possible values of this state are UP, DOWN, NOT_CONFIGURED when the MongoDB server is not configured in MWM, NOT_SUPPORTED when MWM is not compiled with MongoDB support, and UNKNOWN when MWS cannot communicate with MWM. A message is also present for all down connections except MWM to MongoDB giving a reason for the error state.

{
  "mam": {
    "connected": false,
    "host": "localhost",
    "message": "There was an error connecting to MAM at 'localhost', the secret key does not match.",
    "port": 7112,
    "version": null
  },
  "mongo": {
    "connected": true,

}

4.5 Events

This section describes the URLs, request bodies, and responses delivered to and from Moab Web Services for handling events

The Event API contains the type and description of all fields in the Event object. It also contains details regarding which fields are valid during POST actions.

Supported Methods

ResourceGETPUTPOSTDELETE
/rest/eventsGet all events Create event 
/rest/events/idGet specified event   

Configuration

Logging events to a flat file requires that you make a few changes to the configuration in the log4j section of the mws-config.groovy file so that events will be logged to the events.log file, and all other Moab Web Services logging information will be sent to the mws.log file.

Causing events.log to Roll Based on a Time Window

You can specify how often the events.log file rolls. The following example illustrates the configuration changes you will need make to mws-config.groovy to cause the events.log file to roll based on a time window. (In this example, mws-config.groovy is configured so that events.log rolls daily at midnight.)

Daily rolling events.log configuration in mws-config.groovy
log4j = {
  def eventAppender = new org.apache.log4j.rolling.RollingFileAppender(name: 'events', layout: pattern(conversionPattern: "%m%n"))
  def rollingPolicy = new org.apache.log4j.rolling.TimeBasedRollingPolicy(fileNamePattern: '/tmp/events.%d{yyyy-MM-dd}', activeFileName: '/tmp/events.log')
  rollingPolicy.activateOptions()
  eventAppender.setRollingPolicy(rollingPolicy)

appenders { appender eventAppender

rollingFile name: 'rootLog', file: '/tmp/mws.log', maxFileSize: '1GB' }

root { warn 'rootLog' }

trace additivity:false, events:'com.ace.mws.events.EventFlatFileWriter' }

Note the RollingFileAppender and the TimeBasedRollingPolicy lines. These lines configure Moab Web Services to write the event log to the events.log file.

Rolled log files will have a date appended to their name in this format: 'yyyy-MM-dd' (for example, events.log.2012-02-28).

If you want the event log file to roll at the beginning of each month, change the TimeBasedRollingPolicy "fileNamePattern" date format to 'yyyy-MM'. For example:

Monthly event logs
def rollingPolicy = new org.apache.log4j.rolling.TimeBasedRollingPolicy(fileNamePattern: '/tmp/events.%d{yyyy-MM}', activeFileName: '/tmp/events.log')

If you want the event log file to roll at the beginning of each hour, change the date format to 'yyyy-MM-dd_HH:00'. For example:

Hourly event logs
def rollingPolicy = new org.apache.log4j.rolling.TimeBasedRollingPolicy(fileNamePattern: '/tmp/events.%d{yyyy-MM-dd_HH:00}', activeFileName: '/tmp/events.log')

Configuring events.log to Roll Based on File Size Threshold

You can also configure the events.log file to roll when the log size exceeds a specified threshold. The following example illustrates the configuration changes you will need to make to mws-config.groovy to cause the events.log file to roll on a size threshold. (In this example, mws-config.groovy is configured so that events.log rolls when its size exceeds 50 MB.)

mws-config.groovy configuration that rolls events.log based on file size
log4j = {
  appenders {
      rollingFile name: 'events',
        file: '/tmp/events.log',
        maxFileSize: '50MB',
        maxBackupIndex:10

rollingFile name: 'rootLog', file: '/tmp/mws.log', maxFileSize: '1GB' }

root { warn 'rootLog' }

trace additivity:false, events:'com.ace.mws.events.EventFlatFileWriter' }

Note that maxFileSize is set to '50MB'. This means that when the events.log file exceeds 50 MB, it will roll.

The name for the rolled log will be "events.log.1". When the new events.log file exceeds 50 MB, it will roll and be named "events.log.1", while the old "events.log.1" file will be renamed "events.log.2". This process will continue until the optional maxBackupIndex value is met. In the example above, maxBackIndex is set to 10. This means that Moab Web Services will delete all but the ten most recent events.log files. Using this feature helps prevent hard drives from filling up.

Additivity

The additivity attribute of the EventFlatFileWriter logger can be either "true" or "false". If you specify "true", events will be logged to the events.log file and the mws.log file. If you specify "false", events will be logged to the events.log file only. (All other Moab Web Services logging information will be logged to the mws.log file, as configured by the rootLog appender.)

To log events to the mws.log file in addition to the events.log file, make this configuration: additivity:true. For example:

Logging events to both events.log and mws.log
trace additivity:true, events:'com.ace.mws.events.EventFlatFileWriter'

For more configuration options, see Apache Extras Companion for log4j.

Deleting Old Events

By default, MWS will hold event data in MongoDB indefinitely. However, if disk space is limited, you may want to regularly delete old, unneeded events from MongoDB. This section contains some examples of how you can do this.

Let's say that you want to delete events that are older than 90 days. You could run this script. (There are 86,400,000 milliseconds in a day, so in this example, 90*86400000 corresponds to 90 days in milliseconds.)

Delete events older than 90 days
$ mongo
MongoDB shell version: 2.0.1
connecting to: test
> use mws
> db.event.remove({eventTime:{$lt:new Date(new Date().getTime()-90*86400000)}})
> exit
To create a script to perform this task:

deleteOldEvents.sh
#!/bin/bash
printf 'use mws_dev\ndb.event.remove({eventTime:{$lt:new Date(new Date().getTime()-90*86400000)}})\nexit' | mongo

Now say that you want to set up a cron job ($crontab -e) so that old events are automatically deleted on a certain day of the week (for example, every Sunday at 2:00 a.m.), you would add an entry like this:

cron table entry to delete old events
00 02 * * 0 /root/deleteOldEvents.sh

4.5.1 Getting Events

Querying Events

It is possible to query events by one or more fields based on MongoDB query syntax. The following contains examples of simple and complex event queries and event queries by date.

Simple Queries

To see only events that are of type "jobsubmit":

http://localhost/mws/rest/events?query={"eventType":"jobsubmit"}

To see only events of type "jobsubmit" with the status of "failure":

http://localhost/mws/rest/events?query={"eventType":"jobsubmit","status":"failure"}

To see only events with the "job" facility:

http://localhost/mws/rest/events?query={"facility":"job"}

To see only events in the "start" event category:

http://localhost/mws/rest/events?query={"eventCategory":"start"}

More Complex Queries

You can query on embedded JSON objects within the event JSON. For example, to see events associated with proxyUser bob:

http://localhost/mws/rest/events?query={"initiatedBy.proxyUser":"bob"}

To see only events that are NOT associated with bob:

http://localhost/mws/rest/events?query={"initiatedBy.proxyUser":{"$ne":"bob"}}

When the field values of the desired events are a finite set, you can use the $in operator. For example, to see events that relate to either alice, bob, or charlie:

http://localhost/mws/rest/events?query={"initiatedBy.proxyUser":{"$in":["alice","bob","charlie"]}}

Querying Events by Date

To see events created before January 27, 2012 at 12:08 a.m. UTC:

http://localhost/mws/rest/events?query={"eventTime":{"$lt":"2012-01-27 12:08:00 UTC"}}

To see events created before or on January 27, 2012 at 12:08 a.m. UTC:

http://localhost/mws/rest/events?query={"eventTime":{"$lte":"2012-01-27 12:08:00 UTC"}}

To see all events created after January 27, 2012 at 12:04 a.m. UTC:

http://localhost/mws/rest/events?query={"eventTime":{"$gt":"2012-01-27 12:04:00 UTC"}}

To see all events created after or on January 27, 2012 at 12:04 a.m. UTC:

http://localhost/mws/rest/events?query={"eventTime":{"$gte":"2012-01-27 12:04:00 UTC"}}

To see events created between 12:04 a.m. and 12:08 a.m. UTC inclusive:

http://localhost/mws/rest/events?query={"eventTime":{"$gte":"2012-01-27 12:04:00 UTC","$lte":"2012-01-27 12:08:00 UTC"}}

To see events created between 12:04 a.m. and 12:08 a.m. UTC inclusive that are associated with proxyUser bob:

http://localhost/mws/rest/events?query={"initiatedBy.proxyUser":"bob","eventTime":{"$gte":"2012-01-27 12:04:00 UTC","$lte":"2012-01-27 12:08:00 UTC"}}

To see events created between 12:04 a.m. and 12:08 a.m. UTC inclusive, that are associated with proxyUser bob, and that are of type "jobsubmit":

http://localhost/mws/rest/events?query={"initiatedBy.proxyUser":"bob","eventType":"jobsubmit","eventTime":{"$gte":"2012-01-27 12:04:00 UTC","$lte":"2012-01-27 12:08:00 UTC"}}

Sorting

See the sorting section of Global URL Parameters

Limiting the Number of Results

If you want to limit the number of results of events, you can use the max parameter. For example, to see only 10 "vmmigrate" events:

http://localhost/mws/rest/events?query={"eventType":"vmmigrate"}&sort={"eventTime":1}&max=10

To see "vmcreate" events 51-60 when sorted by eventTime in descending order, you can combine max with offset, as follows:

http://localhost/mws/rest/events?query={"eventType":"vmcreate"}&sort={"eventTime":-1}&max=51&offset=60

Retrieving a Subset of Fields

To cause only certain fields to return for each event, use the fields parameter. For example, to show only the eventTime field for each event:

http://localhost/mws/rest/events?max=3&fields=eventTime

This returns:

{
  "totalCount": 187,

Sample Response

If the request was successful, the response will be an object with an id property containing the ID of the newly created events. On failure, the response is an error message.

JSON Response
[{"id":"4fadd83bc4aa366464599e1a"},{"id":"4fadd83bc4aa366464599e1b"},{"id":"4fadd83bc4aa366464599e1c"}]

Below is an example of events.log output for a successful event request:

Note that " (double quote) characters in the input have been replaced by \" characters in the output. (For other character restrictions, see the "Restrictions" section below.)

Restrictions

Special characters, such as newline, carriage return, and " (double quote) are encoded in the output of events.log to make events.log easy to parse with scripts and third party tools. For example, if the input XML contains:

<ErrorMessage>RM says, "Cannot provision vm21"</ErrorMessage>
Then the following will be output to events.log:
error.message="RM says, \"Cannot provision vm21\""
Notice that " has been replaced with \". This table contains the most common encodings.

CharacterEscape Sequence 
" (double quote)\" 
\ (backslash)\\
 
newline\n 
carriage return\r 
tab\t 

(For more information see escape sequences for Java Strings.)

Other restrictions include:

  • Detail names can only contain alpha-numeric characters, colons (:), underscores (_), and dashes (-).
  • primaryObject.serialization, error.message, and detail values (for example detail.someName="some value") can contain any printable ASCII character. Single quotes (') and double quotes (") cannot be contained in any other field.
  • A single event cannot contain more than more than 50 details. If an event has more than 50 details, the excess details will be ignored.

sortNoJSONSort the results. Use 1 for ascending and -1 for descending.sort={"name":-1}

It is possible to query images by one or more fields based on MongoDB query syntax.

See Global URL Parameters for available URL parameters.

Sample Response

GET http://localhost/mws/rest/images?fields=id,name
{
  "totalCount": 1,
  "resultCount": 1,
  "results": [  {
    "id": "4fa197e68ca30fc605dd1cf0",
    "name": "centos5-stateful"
  }]
}

Sorting and Querying

See the sorting and querying sections of Global URL Parameters.

4.7.1.2 Get Single Image

URLs and Parameters

GET http://localhost/mws/rest/images/<id>
GET http://localhost/mws/rest/images/<name>

ParameterRequiredTypeValid ValuesDescription
idYesString-The unique identifier of the Image.
nameYesString-The name of the Image.

See Global URL Parameters for available URL parameters.

You must specify either id or name, but you do not have to specify both.

Sample Response

Virtual machine image example:

GET http://localhost/mws/rest/images/centos5-compute-stateful
{
  "active":true,
  "extensions":{
    "xcat":{
      "os":"centos",
      "architecture":"x86_64",
      "profile":"compute"
    }
  },
  "features":[],
  "hypervisor":false,
  "hypervisorType": null,
  "id":"4fa197e68ca30fc605dd1cf0",
  "name":"centos5-compute-stateful",
  "osType":"linux",
  "supportsPhysicalMachine":false,
  "supportsVirtualMachine":true,
  "templateName":"",
  "type":"stateful",
  "version":0,
  "virtualizedImages":[]
}

Hypervisor image example:

GET http://localhost/mws/rest/images/esxi-4.1-stateful
{
  "active":true,
  "extensions":{
    "xcat":{
      "hvGroupName":"hvGroup",
      "vmGroupName":"vmGroup",
      "os":"esxi-4.1",
      "architecture":"x86_64",
      "profile":"hv"
    }
  },
  "features":[],
  "hypervisor":true,
  "hypervisorType":"ESX",
  "id":"4fa197e68ca30fc605dd1cf0",
  "name":"centos5-compute-stateful",
  "osType":"linux",
  "supportsPhysicalMachine":true,
  "supportsVirtualMachine":false,
  "templateName":"",
  "type":"stateful",
  "version":0,
  "virtualizedImages":[]
}

The version field contains the current version of the database entry and does not reflect the version of the operating system. See Modify Image for more information.

4.7.2 Creating Images

The HTTP POST method is used to submit Images.

Quick Reference

POST http://localhost/mws/rest/images

4.7.2.1 Create Single Image

URLs and Parameters

POST http://localhost/mws/rest/images

See Global URL Parameters for available URL parameters.

Request Body

Three fields are required to submit an image: name, hypervisor, and osType. Each image must also support provisioning to either a physical machine or a virtual machine by using the supportsPhysicalMachine or supportsVirtualMachine fields.

The name field must contain only letters, digits, periods, dashes, and underscores.

The array of virtualized images are themselves objects that contain image IDs or names. For more information on available fields and types, see the Image API.

The following is an example of the most basic image that can be created:

POST http://localhost/mws/rest/images
{
  "name": "centos5-stateful",
  "osType": "linux",
  "hypervisor": false,
  "supportsVirtualMachine":true
}

Note that this example does not provide any information for a provisioning manager (such as xCAT) to actually provision the machine. In order to provide this, you must add an entry to the extensions field that contains provisioning manager-specific information. Each key in the extensions field corresponds to the provisioning manager, and certain properties are required based on this key. For example, the xCAT extension key must be named xcat and must contain certain fields. These extension keys are documented in the Image API. See the following examples of creating images with xCAT-specific provisioning information below.

Sample Response

If the request was successful, the response body is the new image that was created exactly as shown in Get Single Image. On failure, the response is an error message.

Samples

The virtualizedImages field only accepts input when the image is a hypervisor and expects an array of image IDs or names, as shown in the following example:

Example payload of hypervisor with 2 vms
{
  "hypervisor":true,
  "name":"esx5-stateful",
  "osType":"linux",
  "supportsPhysicalMachine":true,
  "type":"stateful",
  "hypervisorType":"ESX",
  "virtualizedImages":   [
    {"id": "4fa197e68ca30fc605dd1cf0"},
    {"name": "centos5-stateful"}
  ]
}

The following example shows how to create an image that utilizes a cloned template for a virtual machine. (Note that the type must be set to linkedclone in order to set the templateName field.)

VM Utilizing a Cloned Template
{
  "active": true,
  "hypervisor": false,
  "name": "centos5-compute-stateful",
  "osType": "linux",
  "type": "linkedclone",
  "supportsVirtualMachine":true,
  "templateName":"centos5-compute"
}

The following are samples of a virtual machine and a hypervisor image that can be provisioned with xCAT:

xCAT Virtual Machine Image
{
  "active": true,
  "features": [],
  "hypervisor": false,
  "name": "centos5-compute-stateful",
  "osType": "linux",
  "type": "stateful",
  "supportsVirtualMachine":true,
  "extensions": { 
     "xcat": { 
        "os": "centos",
        "architecture": "x86_64",
        "profile": "compute"
     }
  }
}

xCAT Hypervisor Image
{
  "active": true,
  "features": [],
  "hypervisor": true,
  "name": "esxi5-base-stateless",
  "osType": "linux",
  "virtualizedImages":   [
    {"name": "centos5-compute-stateless"}
  ],
  "type": "stateless",
  "hypervisorType": "ESX",
  "supportsPhysicalMachine":true,
  "extensions": { 
     "xcat": { 
        "os": "esxi5",
        "architecture": "x86_64",
        "profile": "base",
        "hvType": "esx",
        "hvGroupName": "esx5hv",
        "vmGroupName": "esx5vm"
     }
  }
}

4.7.3 Modifying Images

The HTTP PUT method is used to modify Images.

Quick Reference

PUT http://localhost/mws/rest/images/<id>
PUT http://localhost/mws/rest/images/<name>

4.7.3.1 Modify Single Image

URLs and Parameters

PUT http://localhost/mws/rest/images/<id>
PUT http://localhost/mws/rest/images/<name>

ParameterRequiredTypeValid ValuesDescription
idYesString-The unique identifier of the Image.
nameYesString-The name of the Image.

See Global URL Parameters for available URL parameters.

  • You must specify either id or name, but you do not have to specify both.
  • The name field must contain only letters, digits, periods, dashes, and underscores.

Example Request

PUT http://locahost/mws/rest/images/centos5-stateful
{
  "name": "centos5-stateful",
  "type": "stateful",
  "hypervisor": false,
  "osType": "linux",
  "virtualizedImages": []
}

The version field contains the current version of the database entry and does not reflect the version of the operating system. This field cannot be updated directly. However, if version is included in the modify request, it will be used to verify that another client did not update the object in between the time the data was retrieved and the modify request was delivered.

Sample Response

If the request was successful, the response body is the modified image as shown in Get Single Image. On failure, the response is an error message.

4.7.4 Deleting Images

The HTTP DELETE method is used to delete Images.

Quick Reference

DELETE http://localhost/mws/rest/images/<id>
DELETE http://localhost/mws/rest/images/<name>

4.7.4.1 Delete Single Image

URLs and Parameters

DELETE http://localhost/mws/rest/images/<id>
DELETE http://localhost/mws/rest/images/<name>

ParameterRequiredTypeValid ValuesDescription
idYesString-The unique identifier of the Image.
nameYesString-The name of the Image.

See Global URL Parameters for available URL parameters.

Only one of id or name are required.

Job Arrays

If a job is the master of a job array, the response will have some additional fields set as shown in the following example. The name field is chosen by the Moab Workload Manager, and the customName field comes from the job array name field.

Job Array Master
{
  "name": "Moab.5",
  "customName": "myarray",
  "flags":   [
    "ARRAYMASTER",
    "GLOBALQUEUE",
    "CANCELONFIRSTFAILURE",
    "CANCELONANYSUCCESS"
  ]
}

If a job is a sub-job of an array, the response will have other fields set as shown in the following example.

Array Sub-Job
{
  "name": "Moab.5[21]",
  "customName": "myarray",
  "arrayIndex": 21,
  "arrayMasterName": "Moab.5",
  "flags":   [
    "ARRAYJOB",
    "GLOBALQUEUE",
    "CANCELONFIRSTFAILURE",
    "CANCELONANYSUCCESS"
  ]
}

Sample Response

The response of this task is one of three possibilities:

  • An object with a single messages property containing a list of error messages on failure

{"messages":["Could not create job - invalid requirements"]}
  • An object with a name property containing the name of the newly created job

{"name":"Moab.1"}
  • An object with a name property and a virtualContainers list containing the name of the newly created virtual container

{ "name": "Moab.1", "virtualContainers": [{"name": "vc1"}] }

The virtual container will only be reported when a new virtual container has been created by Moab for the job.

4.8.2.2 Examples of Job Submission

This section includes some sample job submission requests.

Submit job to run on node2 and node3

POST http://localhost/mws/rest/jobs?api-version=2
{
  "commandFile": "/tmp/test.sh",
  "credentials":   {
    "group": "adaptive",
    "user": "adaptive"
  },
  "initialWorkingDirectory": "/tmp",
  "nodesRequested":   [
    {"name": "node2"},
    {"name": "node3"}
  ]
}

Submit job that requires 20 processors

POST http://localhost/mws/rest/jobs?api-version=2
{
  "commandFile": "/tmp/test.sh",
  "credentials":   {
    "group": "adaptive",
    "user": "adaptive"
  },
  "initialWorkingDirectory": "/tmp",
  "requirements": [{"taskCount": 20}]
}

Submit job to run after a certain time

POST http://localhost/mws/rest/jobs?api-version=2
{
  "commandFile": "/tmp/test.sh",
  "credentials":   {
    "group": "adaptive",
    "user": "adaptive"
  },
  "dates": {"earliestRequestedStartDate": "2012-10-11 18:36:35 UTC"},
  "initialWorkingDirectory": "/tmp",
  "requirements": [{"taskCount": 20}]
}

Submit job based on msub example

Given this msub command:

msub -l nodes=3:ppn=2,walltime=1:00:00,pmem=100 script2.pbs.cmd

Here is an equivalent MWS request:

POST http://localhost/mws/rest/jobs?api-version=2
{
  "duration": 3600,
  "commandFile": "/home/adaptive/script2.pbs.cmd",
  "credentials":   {
    "group": "adaptive",
    "user": "adaptive"
  },
  "initialWorkingDirectory": "/home/adaptive",
  "requirements": [  {
    "resourcesPerTask": {"memory": {"dedicated": 100}},
    "taskCount": 6,
    "tasksPerNode": 2
  }]
}

  • To emulate what msub does, make commandFile an absolute path, and add credentials.user, credentials.group, and initialWorkingDirectory.
  • As shown above, nodes=3:ppn=2 is equivalent to setting taskCount to 6 and tasksPerNode to 2.

Submit a Job Array

See the Submitting Job Arrays section for details on how to submit a job array.

  }]
}

Generic vs Non-Generic Types

If generic job templates are used in Moab, MWS may be configured to translate pending actions with the generic type to the proper type such as VMCREATE. This is done in the configuration file. The Quickstart Guide provides the default mappings for this feature, as well as an example of adding a custom mapping from a custom template name to the correct type.

The default mappings are shown in the table below. The available pending action types may be seen on the PendingActionType API page.

Template NameMapped Type
genericVM-setupVMCREATE
genericVM-migrateVMMIGRATE
genericVM-destroyVMDESTROY
OSStorage-setupVMSTORAGE
OSStorage-destroyVMSTORAGEDESTROY
extraStorage-setupSTORAGE
extraStorage-destroySTORAGEDESTROY
genericPM-setupOSPROVISION

When generic mappings are used, MWS will match the first template mapping that the pending action ID ends with. For example, an ID of Moab.1.genericVM-setup will map the type to VMCREATE.

To enable mapping for a custom template name such as myCustomVM-setup, simply add the following line to the MWS configuration file. The value of the pending action type is case insensitive.

mws.pendingActions.mappings["myCustomVM-setup"] = "vmcreate"

MWS also provides the ability to enable or disable the display of generic pending actions (or those pending actions that are not mapped). This behavior is controlled by the mws.pendingActions.displayGeneric setting as shown below. A false value will prevent generic pending actions from being displayed, while a true value will display all pending actions. By default this value is true.

mws.pendingActions.displayGeneric = false

All HTTP methods can be used to access Plugin Web Services. However, some services only support specific methods. Check the specific plugin type documentation for more information.

Quick Reference

GET http://localhost/mws/rest/plugins/<id>/services/<serviceName>
POST http://localhost/mws/rest/plugins/<id>/services/<serviceName>
PUT http://localhost/mws/rest/plugins/<id>/services/<serviceName>
DELETE http://localhost/mws/rest/plugins/<id>/services/<serviceName>

4.15.5.1 Access a Plugin Web Service

URLs and Parameters

GET http://localhost/mws/rest/plugins/<id>/services/<serviceName>
POST http://localhost/mws/rest/plugins/<id>/services/<serviceName>

ParameterRequiredTypeValid ValuesDescription
idYesString-The unique identifier of the object.
serviceNameYesString-The name of the web service, either in CamelCase or hyphenated.

See Global URL Parameters for available URL parameters.

Web Service IDs

Translation is done to map CamelCase web service names to hyphenated names in the URL. For example, a web service method named notifyEvent on a plugin with a name of notifications may be called with the following URLs:

// CamelCase
/rest/plugins/notifications/services/notifyEvent

// Hyphenated /rest/plugins/notifications/services/notify-event

HTTP Method and Request Body

Because plugin Custom Web Services do not need to distinguish which HTTP method is used, it is recommended to use GET and POST when making requests to access web services unless documented otherwise. The request body and output may vary for each web service called. See the plugin type documentation for the requested plugin for available web services, request parameters, and expected output.

4.16 Plugin Types

This section describes behavior of the Plugin Type object in Moab Web Services. It contains the URLs, request bodies, and responses delivered to and from Moab Web Services.

The PluginType API page contains the type and description of all fields in the Plugin Type object. It also contains details regarding which fields are valid during PUT and POST actions.

Supported Methods

ResourceGETPUTPOSTDELETE
/rest/plugin-typesGet all plugin typesCreate or update plugin type  
/rest/plugin-types/idGet specified plugin type   

4.16.1 Getting Plugin Types

The HTTP GET method is used to retrieve Plugin Type information. Queries for all objects and a single object are available.

Quick Reference

GET http://localhost/mws/rest/plugin-types/<id>

4.16.1.1 Get All Plugin Types

URLs and Parameters

GET http://localhost/mws/rest/plugin-types

See Global URL Parameters for available URL parameters.

Sample Response

GET http://localhost/mws/rest/plugin-types?fields=id
{
  "totalCount": 2,
  "resultCount": 2,
  "results":   [
    {"id": "vCenter"},
    {"id": "Native"}
  ]
}

4.16.1.2 Get Single Plugin Type

URLs and Parameters

GET http://localhost/mws/rest/plugin-types/<id>

ParameterRequiredTypeValid ValuesDescription
idYesString-The unique identifier of the object.

See Global URL Parameters for available URL parameters.

Sample Response

}

4.16.2 Creating or Updating Plugin Types

The HTTP PUT method is used to create or update Plugin Types. The Content-Type HTTP header is used to determine if the request contains a single class file as plaintext or the binary data of a JAR file. Each request is explained in the following sections.

Quick Reference

PUT http://localhost/mws/rest/plugin-types[?reload-plugins=false]

There is a known issue with dynamically updating plugin types with typed field injection. See the Add or Update Plugin Types section for more information.

4.16.2.1 Update Plugin Type (File)

URLs and Parameters

PUT http://localhost/mws/rest/plugin-types[?reload-plugins=false]

ParameterRequiredValid ValuesDescription
reload-pluginsNotrue or falseReloads all plugins of this type on successful update. Defaults to true.

See Global URL Parameters for available URL parameters.

Request Body

This function is idempotent, meaning it will create the Plugin Type if it does not exist or update it if it does. The request body is the actual contents of the class file to upload. This web service is an exception to most as it requires a content type of application/x-groovy or text/plain.

If the application/x-groovy or text/plain content types are not used in the request, it will be interpreted as JSON, resulting in a failure.

Plaintext upload
package test

import com.adaptc.mws.plugins.*

class UploadPlugin { static author = "Adaptive Computing" static description = "A sample plugin class" String id

public void configure() throws InvalidPluginConfigurationException { def myConfig = config def errors = [] if (!myConfig.arbitraryKey) errors << "Missing arbitraryKey!" if (errors) throw new InvalidPluginConfigurationException(errors) }

public def customService(Map params) { return params } }

If using the curl library to perform plugin type uploading, the equivalent of the command-line option --data-binary must be used to send the request body. Otherwise compilation errors may be encountered when uploading the plugin type.

Sample Response

The response of this task is the same as the Get All Plugin Types task. The reason that the return of this task is a list is to accommodate the possibility of uploading multiple plugin types in a single JAR file as explained in the next section.

4.16.2.2 Update Plugin Type (JAR)

URLs and Parameters

PUT http://localhost/mws/rest/plugin-types?jar-filename=<filename.jar>[&reload-plugins=false]

ParameterRequiredValid ValuesDescription
jar-filenameYesStringThe filename of the JAR file that is being uploaded.
reload-pluginsNotrue or falseReloads all plugins of this type on successful update. Defaults to true.

See Global URL Parameters for available URL parameters.

Request Body

This function is idempotent, meaning it will create the Plugin Types if they do not exist or update them if they do. The request body is the binary contents of the JAR file to upload. This web service is an exception to most as it requires a content type of application/x-jar.

If the application/x-jar content type is not used in the request, it will be interpreted as JSON, resulting in a failure.

If using the curl library to perform plugin type uploading, the equivalent of the command-line option --data-binary must be used to send the request body. Otherwise compilation errors may be encountered when uploading the plugin type.

Sample Response

The response of this task is the same as the Get All Plugin Types task. Note that when using a JAR file, multiple plugin types may be uploaded in the same request.

Querying Services

It is possible to query services by one or more fields based on MongoDB query syntax.

Simple Queries

To see only services that are associated with the user "bob" you can use a query such as the following:

http://localhost/mws/rest/services?query={"user":"bob"}

To see only services that are of type "vm":

http://localhost/mws/rest/services?query={"type":"vm"}

To see only bob's vm services:

http://localhost/mws/rest/services?query={"user":"bob","type":"vm"}

To see only services that are NOT associated with bob:

http://localhost/mws/rest/services?query={"user":{"$ne":"bob"}}

More Complex Queries

When the field values of the desired services are a finite set, you can use the $in operator. For example, to see services that belong to either bob, alice, or charlie, you can do the following:

http://localhost/mws/rest/services?query={"user":{"$in":["alice","bob","charlie"]}}

You can also query on embedded JSON objects within the service JSON. For example, to see services requesting 3 processors you can use:

http://localhost/mws/rest/services?query={"attributes.moab.job.resources.procs":3}

Conditional Operators

You can perform <, <=, >, >= comparisons using the $lt, $lte, $gt, $gte operators.

OperatorComparison 
$lt< 
$lte<= 
$gt> 
$gte>= 

To see services requesting < 2 processors:

http://localhost/mws/rest/services?query={"attributes.moab.job.resources.procs":{"$lt":2}}

To see services requesting >= 1024 memory:

http://localhost/mws/rest/services?query={"attributes.moab.job.resources.mem":{"$gte":1024}}

Querying Services by Date

To see all services created after February 8, 2012 at 1:00 PM Mountain Standard Time (MST):

http://localhost/mws/rest/services?query={"dateCreated":{"$gt":"2012-02-08 13:00:00 MST"}}

To see services created before or on February 8, 2012 at 1:00 PM Pacific Standard Time (PST):

http://localhost/mws/rest/services?query={"dateCreated":{"$lte":"2012-02-08 13:00:00 PST"}}

To see services created between 12:00 PM and 1:00 PM Eastern Standard Time (EST) on February 8, 2012:

http://localhost/mws/rest/services?query={"dateCreated":{"$lte":"2012-02-08 13:00:00 EST","$gte":"2012-02-08 12:00:00 EST"}}

Querying Services by Containing Service

Services can contain other services. When a service is contained within another service, you can find out what its container is by looking at the parent field. A service that is not contained in any other service is called a top level service. If you want to see only top level services you need to query for services with a null parent.

In MongoDB syntax you query for services whose parent field have a $type of 10 (with 10 representing null). The following query shows all of bob's top level services:

http://localhost/mws/rest/services?query={"user":"bob","parent":{"$type":10}}

Once you have the top level service, you can find the direct child services:

http://localhost/mws/rest/services?query={"user":"bob","parent":"bobService.1"}

Once you have the direct children, you can find the children of those children with a similar query.

Sorting

See the sorting section of Global URL Parameters

Limiting the Number of Results

If you want to limit the number of results of services you can use the max parameter. For example, to see only 10 of bob's services:

http://localhost/mws/rest/services?query={"user":"bob"}&sort={"name":1}&max=10

To see bob's services 91-100 when sorted by name in ascending order you can combine max with offset as follows:

http://localhost/mws/rest/services?query={"user":"bob"}&sort={"name":1}&max=10&offset=90

Retrieving a Subset of Fields

To cause only certain fields to return for each service, use the fields parameter. For example, to show only the name field for each service:

http://localhost/mws/rest/services?fields=name

This returns:

{
  "totalCount": 9,
  "resultCount": 3,
  "results":   [
    {"name": "aliceService.1"},
    {"name": "machine0.1"},
    {"name": "OSStoremachine0.1"}
  ]
}

To show the name, type, and user:

http://localhost/mws/rest/services?fields=name,type,user

This returns:

{
  "totalCount": 9,
  "resultCount": 3,
  "results":   [
    {
      "name": "aliceService.1",
      "type": "container",
      "user": "alice"
    },
        {
      "name": "machine0.1",
      "type": "vm",
      "user": "alice"
    },
        {
      "name": "OSStoremachine0.1",
      "type": "storage",
      "user": "alice"
    }
  ]
}

4.24.2 Creating Services

The HTTP POST method is used to create a Service.

Quick Reference

POST http://localhost/mws/rest/services

4.24.2.1 Create Service From Service Template

URLs and Parameters

POST http://localhost/mws/rest/services[?proxy-user=bob]

ParameterRequiredValid ValuesDescriptionExample
proxy-userNoStringThe name of the user creating the service.proxy-user=bob

Simple Case

To create a service from the template named "Rhel54VmPlusStorage":

POST http://localhost/mws/rest/services
{
  "user": "steve",
  "account": "cloud",
  "startDateRequested": "2011-11-08 13:18:47 MST",
  "durationRequested": 86400,
  "data":   [
    {
      "name": "MyRhel54VmPlusStorage",
      "serviceTemplate": "Rhel54VmPlusStorage",
    }
  ]
}

Alternatively you can submit:

POST http://localhost/mws/rest/services
{
  "user": "steve",
  "account": "cloud",
  "data":   [
    {
      "name": "MyRhel54VmPlusStorage",
      "serviceTemplate": {
        "name":"Rhel54VmPlusStorage"
      } 
    }
  ]
}

To create a service based on the service template with id "4fbd2d90c4aa4996400bsa5m"

POST http://localhost/mws/rest/services
{
  "user": "steve",
  "account": "cloud",
  "data":   [
    {
      "name": "MyRhel54VmPlusStorage",
      "serviceTemplate": {
        "id":"4fbd2d90c4aa4996400bsa5m"
      } 
    }
  ]
}

Extending a Service Template

If you want to create a service from a service template, but wish to extend the service template with some additional variables or generic resources, you can use the extends field. Extending a service template is also helpful when you wish to override certain values, such as the amount of memory or processors the service requires.

To extend a service template, you will need to determine the extends path for the service you wish to override. The extends path is the name of the top level service, followed by one or more localNames as described in the includedServices field. All but the last <localName> are nested containers inside the top level container. For example:

<top level service name>::<localName>[:<localName>]+

For example, suppose you want to create a new service from the "Rhel54VmPlusStorage" service template, and you want to name this new service "MyRhel54VmPlusStorage". In this example, "Rhel54VmPlusStorage" contains a service template named "SubContainer1". The localName for "SubContainer1" in the "Rhel54VmPlusStorage" includedServices field is "sc1".

Rhel54VmPlusStorage Service Template
{
   "name":"Rhel54VmPlusStorage",
   "type":"container",
   …
   "includedServices":[
      {
         "localName":"sc1",
         "serviceTemplate":"SubContainer1"
      }
   ]
}

The extends path for the instance of "SubContainer1" in your "MyRhel54VmPlusStorage" is:

MyRhel54VmPlusStorage::sc1

Let's say inside "SubContainer1" is another service template called "SubContainer2". The localName for "SubContainer2" as defined in the includedServices field for "SubContainer1" is "sc2".

SubContainer1 Service Template
{
   "name":"SubContainer1",
   "type":"container",
   …
   "includedServices":[
      {
         "localName":"sc2",
         "serviceTemplate":"SubContainer2"
      }
   ]
}

The extends path for the instance of "SubContainer2" in "MyRhel54VmPlusStorage" is:

MyRhel54VmPlusStorage::sc1:sc2

Now let's say that "SubContainer2" contains two service templates, "Rhel54Vm" and "OpsysStorage" with localNames "rvm" and "oss" respectively.

SubContainer1 Service Template
{
   "name":"SubContainer2",
   "type":"container",
   …
   "includedServices":[
      {
         "localName":"rvm",
         "serviceTemplate":"Rhel54Vm"
      },
      {
         "localName":"oss",
         "serviceTemplate":"OpSysStorage"
      }
   ]
}

The extends paths for the instances of "Rhel54VM" and "OpSysStorage" in "MyRhel54VmPlusStorage" are:

MyRhel54VmPlusStorage::sc1:sc2:rvm
MyRhel54VmPlusStorage::sc1:sc2:oss

Now that we have the extends paths for all the services that will be created from the "Rhel54VmPlusStorage" template, we can add variables to these services that were not in the service templates.

POST http://localhost/mws/rest/services
{
  "user": "steve",
  "account": "cloud",
  "data":   [
        {
      "name": "MyRhel54VmPlusStorage",
      "serviceTemplate": "Rhel54VmPlusStorage",
      "attributes": {
         "sharedData":{ "extraAttribute":"some attribute not in the Rhel54VmPlusStorage template" }
      }
    },
    {
      "name": "MyRhel54Vm",
      "extends": "MyRhel54VmPlusStorage::sc1:sc2:rvm",
      "attributes": {
          "moab": {"job": {"variables": {"extraVar": "An additional variable not in the Rhel54Vm template"}}},
          "sharedData":{ "extraAttribute":"some attribute not in the Rhel54Vm template" }          
      }

}, { "name": "MyOsStorage", "extends": "MyRhel54VmPlusStorage::sc1:sc2:oss", "attributes": { "moab": {"job": {"variables": {"extraVar2": "An additional variable not in the OpSysStorage template"}}}, "sharedData":{ "extraAttribute":"some attribute not in the OpSysStorage template" } } } ] }

When the "MyRhel54Vm" service is created, it will have a variable named "extraVar" even though this variable was not defined in the "Rhel54Vm" service template. Likewise, when the "MyOsStorage" service is created, it will have a variable named "extraVar2", even though no such variable was defined in the "OsStorage" service template. All three services will have an attribute named "extraAttribute" in their attributes.sharedData sections though "extraAttribute" does not appear in any service template.

Extending Services and Dependencies in a Container Service

To add a services to a container service that were not in the container's service template you first define the new services in the service request. Then you extend the includedServices field of the container with the newly defined services. This will add the new services to any that are already in the container as defined in the service template. It is only possible to add services to a container. It is not possible to remove services from a container that were defined in the container's service template.

For example, say the CentosVmPlusStorage service template contains an OpSysStorage service template and a CentosVm service template.

CentosVmPlusStorage Service Template
{
   "name":"CentosVmPlusStorage",
   "type":"container",
   …
   "includedServices":[
      {
         "localName":"oss",
         "serviceTemplate":"OpSysStorage"
      },
      {
         "localName":"cvm",
         "serviceTemplate":"CentosVm"
      }
   ]
}

To add two storage services to the service created from the CentosVmPlusStorage service template submit the following service request:

POST http://localhost/mws/rest/services
{
   "user":"bob",
   "account":"cloud",
   "data":[
      {
         "name":"BobsCentosVmPlusStorage",
         "serviceTemplate":"CentosVmPlusStorage",
         "includedServices":[
            "NewStorageToAdd1",
            "NewStorageToAdd2"
         ]
      },
      {
         "name":"NewStorageToAdd1",
         "serviceTemplate":"ExtraStorage"
      },
      {
         "name":"NewStorageToAdd2",
         "serviceTemplate":"ExtraStorage"
      }
   ]
}
The resulting service BobsCentosVmPlusStorage will contain NewStorageToAdd1, NewStorageToAdd2, a service created from the OpSysStorage template, and a service created from the CentosVm template. To add a dependency such that the CentosVm service will not be able to start until both NewStorageToAdd1 and NewStorageToAdd2 have been set up:

POST http://localhost/mws/rest/services
{
   "user":"bob",
   "account":"cloud",
   "data":[
      {
         "name":"BobsCentosVmPlusStorage",
         "serviceTemplate":"CentosVmPlusStorage",
         "includedServices":[
            "NewStorageToAdd1",
            "NewStorageToAdd2"
         ],
         "attributes":{
            "moab":{
               "dependencies":[
                  {
                     "service":"BobsCentosVm",
                     "dependency":[
                        "NewStorageToAdd1",
                        "NewStorageToAdd2"
                     ]
                  }
               ]
            }
         }
      },
      {
         "name":"BobsCentosVm",

Querying Service Templates

It is possible to query service templates by one or more fields based on the MongoDB query syntax.

Simple Queries

To see only service templates that are associated with the user "bob", use a query like the following:

http://localhost/mws/rest/service-templates?query={"user":"bob"}

To see only service templates that are of type "vm":

http://localhost/mws/rest/service-templates?query={"type":"vm"}

To see only bob's vm service templates:

http://localhost/mws/rest/service-templates?query={"user":"bob","type":"vm"}

To see only service templates that are NOT associated with bob:

http://localhost/mws/rest/service-templates?query={"user":{"$ne":"bob"}}

More Complex Queries

When the field values of the desired service templates are a finite set, use the $in operator. For example, to see service templates that belong to either bob, alice, or charlie, do the following:

http://localhost/mws/rest/service-templates?query={"user":{"$in":["alice","bob","charlie"]}}

You can also query on embedded JSON objects within the service template JSON. For example, to see service templates requesting 3 processors, do the following:

http://localhost/mws/rest/service-templates?query={"attributes.moab.job.resources.procs":3}

Conditional Operators

You can perform <, <=, >, >= comparisons using the $lt, $lte, $gt, $gte operators.

OperatorComparison 
$lt< 
$lte<= 
$gt> 
$gte>= 

To see service templates requesting < 2 processors:

http://localhost/mws/rest/service-templates?query={"attributes.moab.job.resources.procs":{"$lt":2}}

To see service templates requesting >= 1024 memory:

http://localhost/mws/rest/service-templates?query={"attributes.moab.job.resources.mem":{"$gte":1024}}

Querying Service Templates by Date

To see all service templates modified after July 4, 2011 at 10:30:00 PM Mountain Standard Time (MST):

http://localhost/mws/rest/service-templates?query={"modified":{"$gt":"2011-07-04 22:30:00 MST"}}

To see service templates modified before July 6, 2011 at 12:00 AM Pacific Standard Time (PST):

http://localhost/mws/rest/service-templates?query={"modified":{"$lt":"2011-07-06 00:00:00 PST"}}

To see service templates modified between 12:00 AM and 11:59 PM (inclusive) Eastern Standard Time (EST) on July 5, 2011

http://localhost/mws/rest/service-templates?query={"modified":{"$gte":"2011-07-05 00:00:00 EST","$lte":"2011-07-05 23:59:00 EST"}}

Sorting

See the sorting section in Global URL Parameters.

Limiting the Number of Results

To limit the size of the result set, use the max parameter. For example, to see only 10 of bob's services:

http://localhost/mws/rest/service-templates?query={"user":"bob"}&sort={"name":1}&max=10

To see bob's service templates 91-100 when sorted by name in ascending order, combine max with offset as follows:

http://localhost/mws/rest/service-templates?query={"user":"bob"}&sort={"name":1}&max=10&offset=90

Retrieving a Subset of Fields

To retrieve only certain fields, use the fields parameter. For example, to show only the name field for each service:

http://localhost/mws/rest/service-templates?fields=name

This returns:

{
  "totalCount": 9,
  "resultCount": 3,
  "results":   [
    {"name": "aliceService.1"},
    {"name": "machine0.1"},
    {"name": "OSStoremachine0.1"}
  ]
}

To show the name, type, and user:

http://localhost/mws/rest/service-templates?fields=name,type,user

This returns:

{
  "totalCount": 9,
  "resultCount": 3,
  "results":   [
    {
      "name": "aliceService.1",
      "type": "container",
      "user": "alice"
    },
        {
      "name": "machine0.1",
      "type": "vm",
      "user": "alice"
    },
        {
      "name": "OSStoremachine0.1",
      "type": "storage",
      "user": "alice"
    }
  ]
}
