If you remove resources from the environment or no longer require monitoring, you have the option of deleting the resources along with the collected performance data. In this case, all associated components displayed in the Ops Center Analyzer UI (such as CPU, memory, NIC, HBA, Disk, and VM for hypervisors) are removed, along with the performance data stored in the Analyzer detail view database.

When you remove the monitored resources, you must also delete the related probe instance. Otherwise, the resources are eventually detected and added back to the probe instance.

CAUTION:
  • When a probe instance monitors multiple resources and you selectively remove a specific monitored resource, you must still delete the probe instance. When you delete the probe instance, the probe stops the data collection of all other associated resources. To resume the data collection of other associated resources, you must recreate the probe instance and add the resources.
  • Ensure that you choose the correct resources to remove; the monitoring configuration and performance data is deleted and you cannot restore. If you remove the wrong resources by mistake and the probe instance is still in place, the resources are eventually detected and added again, but the historical performance data is lost, and you must redefine the consumer and threshold configuration. (Depending on the size of the configuration, the process of detecting and adding these resources may take a few hours.)
  • Removing a probe instance and all the associated resources reduces the Analyzer detail view license node count.

To remove resources, you must first stop the probe, wait until the data transmission is complete, remove the monitored resources, and then delete the probe.

  1. Log on to the Analyzer probe server UI, and stop the probe from the Status window.
  2. Wait until the data transmission is complete, which takes about 30 minutes. Verify the data import status of the probe instance that you want to delete on both Analyzer probe server and Analyzer detail view.
    1. From the Analyzer probe server Status window, verify the last data collection time of Performance Data and Configuration Data for the probe.
    2. From the Analyzer detail view dashboard, click the Server Status icon. From the Status window, verify the Last Configuration Import Time and Last Performance Import Time for the probe.
  3. From the Ops Center Analyzer UI, click the Administration tab and select Resource Management.
  4. Select the resource tab you want.
  5. Select the check boxes for the resources you want to remove and click Remove.

  6. The list of resources to be deleted appears in a new window. Click OK.
  7. Because the removal cannot be undone, you are prompted to confirm your choice. Click OK.
  8. To delete the probe, go to the Analyzer probe server UI, from the Status window, search for the probe that you want to delete, select the probe and then click Delete.
The resources are removed in the background. If you have deleted a probe instance and the associated resources to reduce a license node count, you do not need to wait until the information has been updated to configure additional resources. You can later confirm that a license node has been released, as described in "Viewing and updating the Analyzer detail view license" in the Hitachi Ops Center Analyzer Installation and Configuration Guide.
