VMware Aria Operations includes a central page where you can monitor and manage the nodes in your VMware Aria Operations cluster and the adapters that are installed on the nodes.

How Cluster Management Works

Cluster management lets you view and change the online or offline state of the overall VMware Aria Operations cluster or the individual nodes. In addition, you can activate or deactivate high availability (HA) and view statistics related to the adapters that are installed on the nodes.

Where You Find Cluster Management

From the left menu, click Administration > Control Panel, and then click the Cluster Management tile.

Cluster Management Options

The options include cluster-level monitoring and management features.

Table 1. Initial Setup Status Details
Option Description
Actions Expand Actions.
  • Click Network Time Protocol Settings to set the global network time protocol settings for your cluster. For more information see the 'Configuring the Global Network Time Protocol (NTP) Settings' topic in the VMware Aria Operations Configuration Guide.
  • Click Rebalance to rebalance the adapter, disk, memory, or network load across VMware Aria Operations cluster nodes to increase the efficiency of your environment.
Cluster Status Displays the online, offline, or unknown state of the VMware Aria Operations cluster.

Once CA is activated, it displays the status of the two fault domains.
High Availability Indicates whether HA is activated, deactivated, or degraded.
Continuous Availability Indicates whether CA is activated, deactivated, or degraded.

VMware Aria Operations provides node-level information and a toolbar for taking nodes online or offline.

Table 2. Nodes in the VMware Aria Operations Cluster
Option Description
Node Name Machine name of the node.

The node that you are logged into displays a dot next to the name.

Node Address Internet protocol (IP) address of the node. Primary and replica nodes require static IP addresses. Data nodes can use DHCP or static IP.
Cluster Role Type of VMware Aria Operations node: primary, data, replica, or witness node (only applicable for CA).
Fault Domain Displays the fault domain a node is associated to in a CA activated cluster.
Note: This column appears only if CA is activated.
Node Pair Displays which pair the node belongs to. For example, in CA, nodes are added in pairs. If there are four nodes, the column displays whether the node is part of pair one or two.
Note: This column appears only if CA is activated.
State Running, Not Running, Going Online, Going Offline, Inaccessible, Failure, Error
Status Online, offline, unknown, or other condition of the node.
Objects in Process Total environment objects that the node currently monitors.
Objects Being Collected Total environment objects that the node collected.
Metrics in Process Total metrics that the node has discovered since being added to the cluster.
Metrics Being Collected Total metrics the node has collected since being added to the cluster.
Version Displays the VMware Aria Operations software version and the build number installed on the node.

In addition, there are adapter statistics for the selected node.

Table 3. Adapters on Server
Option Description
Name Name that the installing user gave to the adapter.
Status Indication of whether the adapter is collecting data or not.
Objects Being Collected Total environment objects that the adapter currently monitors.
Metrics Being Collected Total metrics that the adapter has collected since being installed on the node.
Last Collection Time Date and time of the most recent data collection by the adapter.
Added On Date and time when the adapter was installed on the node.
