Viewing nodes

3.2 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 and virtual machines (VMs) in your data center in tile view. It also allows you to select one specific node to view its details. Likewise in a node detail view, you can view summaries of all the associated VMs in a tile view, and you can select a specific VM to view its details. In the nodes and VMs 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. They also appear and in the detail view of services on the View Services 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
Alias	An alternate name for the resource
Hypervisor type	Type of hypervisor
Image	Operating system
IP	IP address
State	State of the node (for example, Idle or Running)
Total memory	Total amount of memory
Total processors	Total number of processors
VM count	Number of VMs associated with the node (for example, 3)
OS	Operating system

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
Available memory	Amount of available memory
Available processors	Number of available processors
Events	List of generic events associated with the node
Has pending actions	Either Yes or No
Has reservations	Either Yes or No
Health	One of OK, Unknown, Warning, or Failure (for more information, see Understanding health/state information)
Load	CPU load
Power	Either On or Off
VLAN	Virtual LAN name

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