Operations Manager log flooded with 11903 errors due to "Virtual Hard Disk free disk space" monitor RRS feed

  • Question

  • Management Pack: Microsoft Windows Hyper-V 2012 R2 Monitoring (7.1.10104.0)
    Monitor: Virtual Hard Disk free disk space

    There appears to be an issue with this monitor. Every hour, each of my Hyper-V servers is reporting dozens of errors similar to the following. It seems like there is a disconnect between the expected return type (integer) and the actual type (decimal) when checking the free space on VHDX files.

    Log Name:      Operations Manager
    Source:        Health Service Modules
    Date:          2/5/2014 7:59:47 AM
    Event ID:      11903
    Task Category: None
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      BEAST.corp.technologytoolbox.com
    The Microsoft Operations Manager Expression Filter Module could not convert the received value to the requested type.

    Property Expression: Property[@Name='Microsoft:9AC8FCAB-800D-424F-ABCB-747063E5FCF1\559D22F4-A565-4AD4-9B71-44FC5D815C0C\0\0\L.FreeSpace']

    Property Value: 488033.99609375

    Conversion Type: DataItemElementTypeInteger(5)

    Original Error: 0x80FF005A

    One or more workflows were affected by this.

  • Hi,

    I suspect your monitor properties is incorrect. Please re-create a new Virtual Hard Disk free disk space monitor for a test.

  • I'm confused.

    Your response states to "re-create" the VHD free disk space monitor, but I did not create the monitor in the first place. This monitor was created by importing the Microsoft Windows Hyper-V 2012 R2 Monitoring (7.1.10104.0) management pack. Since that MP is sealed and not exportable, I don't believe there is any way that I can change the monitor.

    Please correct me if I'm missing something.

  • Seeing this same error on my newly built 2012 R2 Hyper-V Server.

  • Hello. People having this issue - what account your agent is running and then - what locales this account have? Does it use DOT or COMMA as a delimiter?

    TIP: For checking the LocalSystem (Computer Account on agent) Regional Settings: HKEY_USERS\.DEFAULT\Control Panel\International

    R.E.M. - YEAH!

  • SCOM agent is running as SYSTEM. (I used to run SCOM agents as a low-privilege domain account but eventually surrendered to "The Dark Side" due to the number of issues encountered with that approach.)

  • same error on 2012 R2 Hyper-V Server.
    Wednesday, February 12, 2014 2:52 PM
  • Any update on this? It has been a week since I provided the information requested by Lukasz.

    Monday, February 17, 2014 5:58 PM
  • It seems like this is a bug. Can anyone from Microsoft please confirm?

    All I'm really looking for is a response that says either "yes, we were able to reproduce it and we've created a work item to get it fixed in a future version of the management pack" or "no, unlike a number of people on this thread, we were unable to reproduce it."

  • Same issue here. I just imported the Hyper-V 2012 R2 monitors and I'm instantly flooded with these events. My HD space is fine. Whats the word?

  • Still hoping for some kind of response regarding this issue.

  • I'm having exactly the same issue here.

  • Same issue here too, on all of our three Hyper-V 2012 R2 hosts.

    I'm also having same issue on 25+ Hyper-V 2012 R2 Hosts.

  • We are also experiencing this issue. Has there been any update since the last post?

    Or is just another case of disable the monitor in SCOM because it's bugged!

  •  A quick look in the Authoring Console shows that the matching value for the Event Level is wrong and set to a string. In the below screenshot I’ve changed the value.

    Witch Sreenshot you mean?

  • I think IGfr is simply ripping his response from a similar issue listed here: http://www.opsmanager.se/2012/11/21/authoring-error-with-event-id-11903/

    Seeing that this is not an event I can't see this helping.

    Eitherway, has anyone managed to resolved this yet?

  • Hi,

    I am having the same issue.

    Until this is being fixed, you can disable the Monitor: Virtual
    Hard Disk free disk space

  • It is MP bug. I have got an answer from Microsoft that it probably will be fixed in next MP release.

  • As well as the errors in Event Viewer, you can also check Server Manager under Hyper-V. It looks like the monitor is trying to open Virtual Disk Drives that have .iso files attached (i.e. vmguest), the alerts in Server Manager will show which ISO's are present - it is worth going through changing the disks to "No Media" on the guests.

    I have disabled the "Monitor: Virtual Hard Disk free disk space" until the bug is resolved.
