SCOM 1801 - Notification channel issues

    Question

  • Here's a good one...

    SCOM 1801 (greenfield site) - it appears that using a Chanel Type "Command" and not filtering alerts at all will result in the command channel only being initiated intermittently.

    Adding both the command channel type and an smtp channel type to a subscription results in the smtp channel firing every time but the command channel hardly ever firing. Nothing in the MOM event logs to indicate hitting any limits \ errors. All my command channel does is write "get-date" in a powershell script to a text file (to test - i thought it might be my script but it isn't).

    Anyone else seen this? Part of me is wishing i installed 2012 R2 for this site!

  • Couldn't it simply be because of the 5 simultaneous cmd notification limit?

  • yes the script runs without issue.

    Remember this is a test script that just contains the following:

    get-date | out-file c:\somefolder\somefile.txt -append

    I'm not hitting the five command limit (which i have upped to 30 any way)

  • Hi Jim,

    Did the command channel type and the smtp channel type firing criteria are same?

    If so, they should be fired at the same time.

    If not, the alert may not reached the command channel type fire criteria.

    Best regards,

  • In command channel setting, pls check
    1) full path of the command file: C:\windows\system32\windowspowershell\v1.0\powershell.exe
    2) Command line parameter: your powershell script file
    3) startup folder for the command line: C:\windows\system32\windowspowershell\v1.0\
    Make sure that your custom powershell script exists on all management server

    Here is my (test) subscription criteria

    Here is my selected subscribers to the subscription

    Here are the channels in use in the subscription


    As you can see, nothing wrong here...

    @system center guy, it fires intermittently - there is nothing wrong with the command channel config.
    The script exists on both management servers, in exactly the same location.

    And for the purpose of completeness...
