Recently we have been provisioning our Hyper-V servers with guest VMs that have their disks thick provisioned, this means that some of the disks on the host Hyper-V server are fully utilized but will never budge and will not require monitoring, while the guests have their disks that do require the monitoring. This requires an override in SCOM otherwise the disk on the host will continue to alert.
In this example we will be disabling the alerts for disk E: on an individual server.
Step 1. Locate the object that requires the override
- Method 1 – From Alerts View
- If the object has alerted then you can locate it easily from the active alerts view
- Method 2 – From Windows Computers View
- Locate the computer within the view, right click and select Open, and Health Explorer
- Turn off the scope that only looks for unhealthy child monitors
- Locate the object (in this case it is unhealthy), right click and select Monitor Properties
- Select the Overrides tab, select the override, click on the Override button and then select the Object
Step 2. Apply the override
In this case we are disabling the object, so you can select the row that has a parameter name of Enabled, and set its override value to False. You can also add a comment to explain why the change is being made. Set which management pack you are creating the override in and then apply.
