My frequently used SCOM Queries

I won't take the credit for most of these queries. I have compiled them overtime from different blogs, sites

/* Database size */

SELECT DB_NAME() AS DbName,
name AS FileName,
size/128.0 AS CurrentSizeMB,
size/128.0 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS INT)/128.0 AS FreeSpaceMB
FROM sys.database_files;.

/*PERFORMANCE related queries*/

select top 20 pcv.ObjectName, pcv.CounterName, count (pcv.countername) as Total from performancedataallview as pdv, performancecounterview as pcv where (pdv.performancesourceinternalid = pcv.performancesourceinternalid) group by pcv.objectname, pcv.countername order by count (pcv.countername) desc

select top 2000 Path,ObjectName, count(ObjectName) from PerformanceDataAllView pdv with (NOLOCK) inner join PerformanceCounterView pcv with (NOLOCK) on pdv.performancesourceinternalid = pcv.performancesourceinternalid inner join BaseManagedEntity bme with (NOLOCK) on pcv.ManagedEntityId = bme.BaseManagedEntityId where  pcv.ObjectName like 'Processor' group by Path,ObjectName order by count(ObjectName) desc

/*Discovery frequencies in the management packs*/

select       ds.DiscoveryName,       mp.MpName,       CAST(md.ModuleConfiguration as XML).value('/Frequency[1]','int') as 'Frequency' from Module (nolock) as md inner join Discovery (nolock) as ds       on md.ParentId = ds.DiscoveryId inner join ManagedType (nolock) as mt       on mt.ManagedTypeId = ds.DiscoveryTarget inner join ManagementPack (nolock) as mp       on mp.ManagementPackId = ds.ManagementPackId

Who is connected to my SCOM console

The following command will help to find who is connected to your SCOM console. This works for SCOM 2012.

(Get-SCOMManagementGroup).getconnectedusernames()

For SCOM 2007 you will have to use the ones below. I have not tested the below commands, though.

Get-ManagementGroupConnection | foreach-object {$_.ManagementGroup.getConnectedUserNames()}
Get-ManagementGroupConnection | foreach-object {$_.ManagementGroup.getConnectedUserNames()} | measure-object

 

Adding or removing a new SCOM zone from Om12 agent

Using Powershell:

Remove Management group

$OMCfg = New-Object -ComObject AgentConfigManager.MgmtSvcCfg;

$OMCfg.RemoveManagementGroup("zonetoberemoved")

 

Add management group

$OMCfg = New-Object -ComObject AgentConfigManager.MgmtSvcCfg;

$OmCfg.AddmanagementGroup(‘zonenametobeadded’,'MSNamewithFQCN',5723)
