SCOM 2012 R2 Powershell脚本监视器未运行

Question

I've created a MP for SCOM 2012 R2 that is supposed to connect to a device using ssh in powershell, get a list of files and hashes for two directories, compare them, and return a result of 'PASS' or 'FAIL'. I'm using the 'ssh-sessions' module from

http://www.powershelladmin.com/wiki/SSH_from_PowerShell_using_the_SSH.NET_library .

The base management pack is from

https://gallery.technet.microsoft.com/Sample-Management-Pack-17b76379 .

If I manually run the script from the management server, it works fine, but if I put it in the MP, and watch my device for an incoming SSH connection, nothing happens. I've tried directly specifying the device's name, as well as passing in $Target/Property[Type="System!System.Entity"]/DisplayName$ , but neither seems to work. I'm stuck as to why SCOM isn't launching the script.

MP Xml below.

TIA

Answer 1

The problem is that your Monitor Target is wrong (the System!System.NetworkDevice is limited to SCOM 2007). For SCOM 2012 and up, you should use the class System.NetworkManagement.Node from the System.NetworkManagement.Library.

So your Unit Monitor should look like this:

<Monitoring>
<Monitors>
  <UnitMonitor ID="UIGeneratedMonitor6114f31ea0204cebb73ba690f5b7bf76" Accessibility="Public" Enabled="false" Target="NetworkManagement!System.NetworkManagement.Node" ...
