Get Parameters that can be Overridden in SCOM 2012 with PowerShell

[アーティクル]
07/19/2013

This is a continuation of a Data Center Automation series of posts that I have been working on with Anders Bengtsson. Here are the first eight posts in this series:

Creating Management Packs in SCOM 2012 with PowerShell
Creating Performance Collection Rules in SCOM 2012 with PowerShell
Creating Event Based Alerting Rules in SCOM 2012 with PowerShell
Enabling or Disabling Workflows in SCOM 2012 with PowerShell
Deleting Workflows in SCOM 2012 with PowerShell
Creating Groups in SCOM 2012 with PowerShell
Adding References to MPs in SCOM 2012 with PowerShell
Modifying Explicit Group Membership in SCOM 2012 with PowerShell

As of this post this script is not included as an activity in the Operations Manager Admin Integration Pack but will be in the next version.

This script supports rules, monitors, discoveries, diagnostics, and recoveries. To get a list of workflows for each type you can run the following commands:

Syntax:

.\GetOveriddableParameters.ps1 –ManagementServer ‘om01.contoso.com’ –WorkflowID ‘custom.example.test.rule.myrule’

Parameters:

Name	Description
ManagementServer	Name of MS to connect to
WorkflowID	ID of the rule, monitor, discovery, diagnostic, or recovery that you want the available overrides for. You can use the output of the PowerShell cmdlets I listed above. This script supports only a single workflow name at this time.

Hi Rus Great article but i have one question. It seems that it dosn't pick up all the parameters that can be overridden. Check the parameters that are available for Microsoft.SystemCenter.Agent.HealthService.HandleCountThreshold It dosnt show that Threshold is an overrideable value so it is not possible to set it using your Set override script. Hope you have some ideas as it is a great script. Thanks Davey
