Perform garbage collection
Perform garbage collection (GC) using the Perform GC option in Nodes administration of OpsCenter monitoring. Performing GC forces the Java Virtual Machine (JVM) on the selected node to perform garbage collection.
|
The Perform GC option in OpsCenter is not the same as the nodetool garbagecollect command. |
-
If OpsCenter role-based security is enabled, be sure that the Garbage Collection Node Operations permission is enabled for the appropriate user roles.
-
Click cluster name > Nodes.
-
In the List view, select one or more nodes.
-
From the Other Actions menu, click Perform GC.
The Perform GC option is also available from the Actions menu in the Node Details dialog.
-
Review the garbage collection confirmation message warning about latency spikes during the operation.
-
Click Run GC to proceed.
Messages appear in the header while garbage collection is in progress and when it is complete. Click the Show Details link to view the progress and outcome on the Activities page.
