SCOM and Mount Point monitoring

We occasionally get questions from the community about monitoring mountpoints. Either for Exchange mount points or SQL servers with mount points. Lately I saw one for Exchange Mount Points and SCOM.

Now, the thing is that Exchange has a lot of built-in monitoring scripts whether you use a monitoring product such as SCOM or not. Of course, in this case it lists all alerts in the event viewer of that server. But there are a lot of checks included in this monitoring and it is split into categories called Health Sets. On a server in my test environment, there are 182 health sets visible, linked to the health state of the many components of Exchange server.

Now, what SCOM does with the Exchange 2013 management pack (which is also for higher versions of Exchange), is to pull in the health state of all these health sets and display them in SCOM. This means that the management pack itself does not contain separate health checks, but rather passes through the state determined already on the server by the underlying scripts from Exchange. Also, there are a lot of Performance collection rules to get all sorts of performance counters from the Exchange serve into SCOM.

Monitoring disk space and so on for several components (databases, logs) of Exchange is part of these checks.

However, sometimes you just want to be able to see statistics of your mounted drives. These do not appear by default in your Logical Disks list in the Windows Server Operating System management packs. This is because they do not have a drive letter assigned and are instead mounted to some path on an existing logical disk. In order to see these disks in SCOM, we need to enable discovery of mounted disks.

First, go to the SCOM Authoring pane. Go to Object Discoveries.

Look for Mount Point. In this picture you see the same discovery for 3 different operating system management packs.

When you enable these discoveries, they will go and find the mount points, and they will be represented in SCOM as Logical Disk. And monitored as such, for disk space for example.

Good luck! Bob Cornelissen
