You can add, edit, or remove collector groups in vRealize Operations Manager, 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 Manager 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 Manager 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 Manager 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 Manager 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

You can manage collector groups by selecting Administration, and clicking Collector Groups.

Table 1. Control Group Summary Grid



Collector Group toolbar

To manage collector groups, use the toolbar icons.

  • Add. Add a collector group

  • Edit. Modify the collector group by adding or removing remote collectors.

  • Delete. Remove the selected collector group.

  • Rebalance collector group. If you have permissions to manage clusters, you can rebalance the workload across the collectors and the remote collectors in the collector group. You can only rebalance one collector group at a time. 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.
