to delete the snapshots. - Compare the metric charts to identify the likely root cause of the alert. See Compare Alerts and Events Over Time in Response to a Datastore Alert .
If you have not activated actions in the vCenter
adapter, you can manually delete the snapshots on your
vCenter Server
instance. - From the left menu, clickTroubleshootand then clickAlerts. Select the alert name in the data grid. The alerts detail information appears on the right.
