Using PowerShell and OpsMgr SDK to Get and Set Management Group Default settings

Over the last couple of days, I have written few additional functions in the OpsMgrSDK PowerShell / SMA module that I’ve been working on over the last few months. Two of these functions are:

  • Get-MGDefaultSettings – Get ALL default settings of an OpsMgr 2012 (R2) management group
  • Set-MGDefaultSetting – Set any particular MG default setting

Since I haven’t seen anything similar to these on the net before, although they will be part of the module when I release it to the public later, I thought they are pretty cool and I’ll publish the code here now.

Get-MGDefaultSettings

This function returns an arraylist which contains ALL the default settings of the management group.

Usage:

$DefaultSettings = Get-MGDefaultSettings -SDK “OpsMgrMS01” –verbose

As you can see, this function retrieves ALL default settings of a management group. It returns the following properties:

  • SettingFullName: The full name of the assembly type of the setting. This is required when using the Set-MGDefaultSetting function to set the value.
  • SettingName: The name of the assembly type of the setting. consider it as the setting category
  • FieldName: The actual name of the setting. It is required when using the Set-MGDefaultSetting function.
  • Value: The current default value of the setting.
  • AllowOverride: When it’s true, this value can be overridden to a particular instance (differ from the default value).

If you want to retrieve a particular setting, you can always use pipe (“|”) and where-object to filter to the particular setting:

Set-MGDefaultSetting

Usage:

Set-MGDefaultSetting -SDK “OpsMgrMS01” -SettingType Microsoft.EnterpriseManagement.Administration.Settings+ManagementGroup+AlertResolution -FieldName AlertAutoResolveDays -Value 3 –verbose

I think these two functions are particularly useful when managing multiple management groups. they can be used in automation products such as SC Orchestrator and SMA, to synchronise settings among multiple management groups (i.e. Test vs Dev vs Prod).
