2008 (Non-R2) Cluster Disks Free Space Monitoring Not Working RRS feed

  • Question

  • We are running SCOM 2012 R2 with the Core OS management pack version 6.0.7061. We are monitoring numerous Server 2008 (Non-R2) SP2 clusters. The MP is discovers all the cluster disks, as I see them all listed as healthy under Monitoring -> Microsoft Windows Server -> Health Monitoring -> Cluster Disk Health.

    However, no Free Space data is being collected. I have no data under Monitoring -> Microsoft Windows Server -> Performance -> Cluster Disk Capacity.

    More importantly, I'm not getting any alerts for Free Space Monitor % or Free Space Monitor MB.

    I've verified that all the Rules and Monitors are enabled for the Cluster Disk target. I've checked the Operations Manager event log on cluster nodes and see event ID 1000 stating that Microsoft.Windows.Server.MonitorClusterDisks.vbs  has executed successfully. I've run the script manually and it does not return anything, but it does not error either, so I assume that's normal.

    Has anyone seen anything similar to this?

    It was issue number 2 in this hotfix. Basically the resource class comes back null without this patch.

  • Thanks Yan. But the current version of the MP (6.0.7061) has some built in collection rules for Free Space MB and Free Space % already. They just don't seem to be working. Neither are the monitors for the same counters, which is really what I would like to get working.

  • Andy,

    I do not have a cluster set up in my current lab, but you mentioned that the objects are discovered under "cluster disk health". do you see the size properties for those disks? also, check http://technet.microsoft.com/en-us/library/dd262028.aspxthe article says "The default health state thresholds for the Logical Disk Free Space monitor are different for system and nonsystem logical disk volumes. Error and Warning health states are based on both percentage of free space and on an absolute value, designated in megabytes (MB), of free space, as shown in the following sections."

    once you confirm that the size shows up, you should be able to configure the monitors to expose the low disk space monitors at the values that you need.

  • Hey Jose,

    Yes, the partition size does show up under Cluster Disk Health.

    There is already a pre-configured Free Space Rollup Monitor for Cluster Disks in the MP that combines free space % and free space MB. There are also rules to collect free space % and free space MB as well. The rules and monitors are what is not working though. I believe both are driven by a script called Microsoft.Windows.Server.MonitorClusterDisks.vbs. I don't know if there is some flawed logic in there for 2008 cluster disks or what. It seems to work fine for 2008 R2 cluster disks and CSVs.

    Thanks,

    Andy
