Users cannot view ACS reports

For the ACS reports the permissions have to be configured in SCOM.
Click Administration–User Roles
If you do not have a role created. Create a new role called “ACS report viewers”
In the tab that opens add the groups in your AD or users in your AD that you would like to have permissions to view reports.

Scom discovery override using powershell

This is script that can be used to modify scom overrides in bulk.
An override management pack must be created first for this to work.
Add this mp name in the $overridemp variable.
Enter the mp that you would like to override in the $mps variable.
## Usage:
## Check the overridable paramters for your discoveries first and then change the parameter you would like to set in $override.Parameter. The format of the parameter may be like
## Selector          : $Config/PeriodInSeconds$. You should only add the “PeriodInSeconds” part
#$disc = Get-SCOMDiscovery -DisplayName “Windows Internet Information Services Web Applications 76-100 Discovery Rule”
## $discovery.GetOverrideableParameters()
Import-module operationsmanager
New-SCOMManagementGroupConnection -ComputerName MyRMS
$mps = Get-SCOMManagementPack |?{$_.name -match “Microsoft.Windows.InternetInformationServices.2003”}
$overridemp = Get-SCOMManagementPack -Name “IIS.Management.Pack.Discovery.Overrides”
$discoveries = Get-SCOMDiscovery -ManagementPack $mps
foreach($discovery in $discoveries)
{
if($discovery.Enabled -ne “false”)
{
$override = $null
$overridemp = Get-SCOMManagementPack -Name “IIS.Management.Pack.Discovery.Overrides”
$Target= Get-SCOMClass -id $discovery.Target.Id
$overridename = $discovery.name + “.Override”
$override = New-Object Microsoft.EnterpriseManagement.Configuration.ManagementPackDiscoveryConfigurationOverride($overridemp,$overridename)
$override.Discovery = $discovery
$override.Module = $discovery.DataSource
$override.Parameter = “PeriodInSeconds”
$override.value = 86400
$override.DisplayName = $overridename
$override.Context = $Target
}
}
$overridemp.Verify() ## This may fail sometimes with a validation error on 2012 R2. So just remove this line and check if your mp imports.
$overridemp.AcceptChanges()

Problem installing Service Manager Authoring Console

SCOM agent less monitoring access denied

Today I was facing and error with monitoring agentless servers. The agent proxy was getting access denied to event logs. In my environment the health services run under the local system account.

I added the server account to administrators on the agentless server but it did not help.

Then I made changes in the default action account profile for the server and and specified another action account instead of the local system action account to run the healthservices under.

Then everything was peachy...

Task to restart health service on agents

https://blogs.technet.microsoft.com/scom_atlas/2015/05/21/task-to-restart-scom-health-service/

Once the management pack is added go to Monitoring-.Windows Computer.

You should see the task in the Tasks pane under Windows Computer Tasks.

 

 

SCOM DataWare House grooming.

Query to check the size of the tables.

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;

Get size of the database.
SELECT DB_NAME(database_id) AS DatabaseName,

Using SCOM get-scomalert criteria

The scom alerts for a particular computer can be retrieved by the following commands.

Get-SCOMAlert -ResolutionState 0 | ?{$_.PrincipalName -match 'SQL' -OR $_.PrincipalName -match 'WEB'}

Get-SCOMAlert -Criteria {ResolutionState = 0 and PrincipalName like '%SQL%'  or PrincipalName like '%WEB%'}}

There is significant difference in the time taken for the two commands to be processed.
