You can add, edit, or remove collector groups in vRealize Operations Cloud, and rebalance your adapter instances.

Rebalancing an Adapter Instance

Rebalancing of your adapter instances is not intended to provide equally distributed adapter instances across each collector in the collector group. The rebalancing action considers the number of resources that each adapter instance collects to determine the rebalancing placement. The rebalancing happens at the adapter instance, which can result in several small adapter instances on a single collector, and a single huge adapter instance on another collector, in your vRealize Operations Cloud instance.

Rebalancing your collector groups can add a significant load on the entire cluster. Moving adapter instances from one collector to another collector requires that vRealize Operations Cloud stops the adapter instance and all its resources on the source collector, then starts them on the target collector.

If a collector fails to respond or loses connectivity to the cluster, vRealize Operations Cloud starts automated rebalancing in the collector group. All other user-initiated manual operations on the collector, such as to stop or restart the collector manually, do not result in automated rebalancing.

If one of the collectors fails to respond, or if it loses network connectivity, vRealize Operations Cloud performs automated rebalancing. In cases of automated rebalancing, to properly rebalance the collector group, you must have spare capacity on the collectors in the collector group.

Where You Manage Collector Groups

From the left menu, click Administration, and then click the Collector Groups tile.

Table 1. Collector Group Summary Grid
Options Description
Collector Group toolbar To manage collector groups, use the toolbar icons.
  • Add. Add a collector group
  • Click the Vertical Ellipses to perform any one of the following actions:
    • Edit. Modify the collector group by adding or removing cloud proxies.
    • Delete. Remove the selected collector group.
    • Rebalance collector group. Rebalance one collector group at a time. If you have permissions to manage clusters, you can rebalance the workload across the collectors and the cloud proxies in the collector group. The rebalance action moves objects from one collector group to another to rebalance the number of objects on each collector in the collector group. If a disk rebalance is already in progress, the collector rebalance does not run.
Collector Group Name The name given to the collector group when the collector group is created.
Description Description given to the collector group when the collector group is created.
