    • Expand Advanced Settings and select the box Evaluate on instance Metrics. Doing this will allow you to exclude the archive file system.
    • Expand Guest File System on the right and then expand /storage/archive.
      Note: If /storage/archive cannot be found, click the square Select Specific Object button to select a VM known to have this metric, filtering for your vCenter Server Appliance.
    • Under the /storage/archive/ filesystem, drag the Partition Utilization (%) metric over so it appears under the list of excluded metric instances.
    • Click Save.
  8. Highlight the symptom definition you just created and click Clone.

    • Drag the new symptoms to the right under the Self-Virtual Machine section.
    • Click Create
  11. Navigate to Configure > Policies > Policy Library.
  12. Select the vSphere Solution Default Policy and click Edit Policy in the top right.
  13. Click Alert/Symptoms Definitions.

  17. Click Save.
  18. Navigate to Configure > Policies > Policy Library.
  19. Click the Add to add a new policy.  Give it a name that identifies it as a custom policy, and tell it to inherit from the vSphere Solution Default Policy that we made changes to in earlier steps of this article
  20. On the last tile, Groups and Objects, assign the policy to the custom group from step 2
  21. Click Save.
Note: After creating the new policy and assigning it to your Custom Group from step 2, use the top right magnifying glass to search for, and navigate to, your vCenter(s).  In the top right, you should see the name of the policy you assigned to the VM(s). 

If you do not, and see another policy listed, navigate back to Policies and using the re-order icon on the right of the policy names, drag your new policy above the old in the hierarchy.
