Disk - Performance Status

Monitoring Benefit
Measuring disk performance helps identify bottlenecks, provides drive failure prediction, and provides trends for capacity planning and scalability.

How do we verify the monitoring test results?

From EMS 8.0 onward these results are held in the ENow SQL database rather than in a file on the web server. Open the monitoring page for this server in the ENow console to review what ENow recorded.

How do we verify the results received on the ENow Client?

The ENow Client is running a WMI query periodically to collect the disk space information. Note that this information is not logged, but the results are stored in the following folder location:

\Program Files (x86)\ENow\Mailscape Agent\Cache\DiskAgentMessage.xml

To capture this from the DC or RODC manually, run the following in PowerShell on that server:

Get-WmiObject -Class Win32_logicaldisk

Based on how the server monitoring component functions, the status of the test is dependent upon the free disk space and the threshold set in the console.

Below is sample output. Values will differ in your environment.

PS C:\Users\Administrator> Get-WmiObject -Class Win32_logicaldisk
