Goal

Collect capacity and free space data (in MB and percent) for the individual guest disks of your virtual machines, for example for application monitoring. The rules for this are turned off by default.

Prerequisites

  • VMware Tools is running on the virtual machines.
  • The OpsLogix IMP - VMware Guest Monitoring Management Pack is imported. See Choose which VMware MP files to import.
  • Permission to create overrides, and a management pack to save them in.

Steps

  1. In the Operations Console, open the Authoring workspace and go to Rules.
  2. Search for vm collect guest disk.
  3. Select one of the rules and choose Overrides > Override the Rule. In a large environment, choose For a group and select a group with only the VMs you need this data for. Every enabled rule collects data for every guest disk of every VM in scope.
  4. Set the Enabled override value to True, select your override management pack and click OK.
  5. Repeat steps 3 and 4 for the other guest disk rules.
  6. Refresh the console. If the new data still doesn't show up, clear the SCOM console cache.

Verify it worked

After the next collection interval (5 minutes), you can see performance data for the VM guest disks.
