Viewing nodes

3.3 Viewing nodes

You can use the View Nodes page to obtain visibility into, and information about, your data center. The View Nodes page offers a holistic view of the nodes in your data center in tile view. It also allows you to select one specific node to view its details. In the nodes tile view, you can use filtering and sorting options to help you quickly find what you're looking for (for details, Understanding "View" pages features).

Access the View Nodes page by navigating to View > Nodes.

Viewing node summaries in tile display

Nodes appear on the View Nodes page.

The View Nodes page will not display any storage node tiles. (Storage nodes are nodes without any processors or memory.)

Tiles also graphically display the node state using the following logic (for more information, see Understanding health/state information):

A node in an OK health state does not display any icon.
A node with a health state other than OK displays the health state.
If a node is in a Requested Actions state but also has a health state of anything other than OK (i.e., Failure, Warning, or Unknown), the health icon will display instead of the Requested Actions icon. The same applies for a Reserved node.
A node in both a Reserved state and Requested Actions state displays the Requested Actions icon.

In addition to displaying the node state, each tile contains summary information about the node it represents, including the following:

Field	Description
Name	Name of the node
State	Running, Idle, etc.
Avail Procs	Number of available processors
Total Procs	Total number of processors
Avail Mem	Amount of available memory
Total Mem	Total amount of memory
Partition	Partition configured in Moab for this node
Uptime	How long the node has been up
Last Update	Date and time the node was last updated

You can use the Filters tool to limit the nodes that display in the tile view, and you can sort the limits that do display by using the Sort tool. For more information, see Understanding "View" pages features.

Viewing node details

Click any node tile to see its detail information. The details view contains all of the same content as the summary tile view and the following additional information:

Field	Description

Generic Resources	Available generic resources on the node
Health	One of OK, Unknown, Warning, or Failure (for more information, see Understanding health/state information)
Last State Update	Date and time the node's state was last updated

Reservation Names	Names of reservations on the node
Generic Events	List of events that have been reported on the node
Has Pending Actions	Either true or false
ID	Node's ID
OS	Operating system installed on the node
Proc Speed	Speed of the processor on the node
Slot	Slot in the rack where the node resides
Current CPU Load	Percent of the CP that is currently being utilized
Generic Metrics	Data regarding the current status of various hardware components within the node
Has Reservations	Either true or false
Index	Index assigned by Moab to the node
Messages	Any messages associated with the node
Rack	The rack number where the node resides

Additionally, if there are any jobs associated with the nodes, they appear as summary tiles in the node detail view. For more information, see Viewing jobs.
