SCOM 2007 SP1 with Base OS MP 6.0.6958 issues with disk monitoring RRS feed

  • Question

  • I am running SCOM 2007 SP1, with the newest Server Base OS MP of 6.0.6958.  I understand there was an issue with the MP and threshold spelled incorrectly.  I removed all overrides for the Logical disk space monitors, and recreated them.  All my logical disks are showing up as monitored and have green checkmarks.  I verified the .vbs script that runs the check is in one of the temp folders within the SCOM agent installation on the servers.  One of our servers dipped below the double threshold, however SCOM still shows the disk as green (OK).  I verified my overrides are setup correctly.  Anyone else run into this curious issue?  I am not sure where else to look.  I open the Events view for the server, and it shows no errors running any scripts or anything.

  • Hi,

    It is an AND condition that determines the free disk space health.

    Your setup logic might be overlapping.

    Try setting the MB levels a liitle far apart. Keep the warning at 15 GB and error at 5 GB

    Percent keep 60 for warning and 40 for error. This might help.

  • Keep in mind that the disk may fall below the threshold and return to healthy anytime within the script interval.  If this happens, the unhealthy condition would not be detected.

    Also, verify that the thresholds are indeed what you expect for unhealthy disk space.  You can use the Logical Disk Free Space Calculator to check this.

  • Based on my understanding, for Logical Disk Free Space Monitor, alert will be generated when both the percentage and the MB thresholds are met. Please double check the overrides settings:

    Hope this helps.

    Thanks.
