System Center 2012: PowerShell Cmdlets

Microsoft has released documents containing ALL the Cmdlets available for ALL the System Center 2012 components.

Since System Center 2012 is PowerShell driven, there is a HUGE collection of cmdlets:

Changing the OperationsManagerACS Database Retention Period

Operations Manager grooms, or removes, data from its various databases at regular configurable intervals. For the Operations database, this is done in the Operations console. For the ACS database, these settings are configured during setup with a default value of 14 days. This means that every day, all database partitions (and their data) that are older than 14 days are dropped or deleted. Because of the volume of data that ACS can accumulate, 14 days is not an unreasonable setting. However, some companies might need to retain data for longer periods and they must have already planned for that when making the sizing and performance calculations for their environment. You can change the retention period for the ACS data by following this procedure.

SCOM 2012: Enable agent proxy on all agents

I kept on getting this alert on the SCOM 2012 console:
"Agent proxy not enabled"

Below is the resolution for enabling the agent proxy for all agents and setting the default value to enable agent proxy for all newly installed agents.

Turn on agent proxy for all agents where it is disabled:
get-SCOMagent | where {$_.ProxyingEnabled -match "False"} | Enable-SCOMAgentProxy

Turn on agent proxy as a default setting for all new agents to be deployed, never to have to mess with this again:
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
new-managementGroupConnection -ConnectionString:scomserver.domain.com;
set-location "OperationsManagerMonitoring::";
Set-DefaultSetting -Name HealthService\ProxyingEnabled -Value True

Thanks to Kevin Holman for his post on this.

Hope that this post was helpful.

Windows Server 2012, SQL Server and System Center 2012

When designing a good System Center 2012 environments it’s obvious that SQL Server is key to the overall success of your design, implementation and functionality of it all.
When a bad decision is made or a good design decision is poorly executed, it has a direct negative impact on the overall experience and functionality of your System Center 2012 environment.
