Get to know your monitor

Ever need to disable a specific monitor?

I know I get tired of clicking through the console, maybe you do too?
Do you know the Monitor name and class?
If yes, then you can enable/disable monitors from PowerShell

 

So let’s get started.

From your management server, you can run SCOM commands as your ID (assuming your ID is set up in SCOM)

 

This example has 2 purposes:

  1. SQL2016 SP1 does NOT populate the proper fields, and will be fixed in SP2 per the SQL Engineering blog (Look at comments section – blog here)
  2. Tired of the warning alerts in my SCOM console

 

Find the monitors

$Monitor = get-scommonitor | where { $_.DisplayName -like “Service Pack Compliance” } | where { $_.Name -like “*Microsoft.SQLServer.2016.DBEngine*” }

 

Let’s focus for a second on some differences, and how you can interchange the two depending on what information you know

DisplayName attribute is what you see in the console (note the spaces)

Name attribute typically has dots for the spaces

 

Override a class

Disable-SCOMMonitor -Class $Class -ManagementPack $MP -Monitor $Monitor

Just in case you need to undo the override

Enable-SCOMMonitor -Class $Class -ManagementPack $MP -Monitor $Monitor

 

Override a group

$Group = (Get-SCOMGroup -DisplayName “Group*”)

 

# Enable the group

Enable-SCOMMonitor -Group $Group -ManagementPack $MP -Monitor $Monitor

 

# Disable the group

Disable-SCOMMonitor -Group $Group -ManagementPack $MP -Monitor $Monitor
