SCOM Management Pack backup


Ever wish you had a backup of your MP?


It’s quite easybutton


Tailor to your requirements, but you can run this as a scheduled task, Orchestrator job, etc.

I would recommend running the script on a server with the Operations Manager shell (or at least add the Operations Manager snapIn to a non SCOM server)

NOTE This will unseal sealed management packs


# Backup Management packs to C drive

# Set up your path, my example is monadmin\backup

$date = Get-Date -UFormat “%Y-%m-%d”


cd monadmin\backup

new-item -itemtype directory -path c:\monadmin\backup\$date

cd $date

# Variants accepted

# Examples – begins with OR, or Company Name, or contains Lab

Get-SCOMManagementPack -Name OR* | Export-SCOMManagementPack -Path “C:\monadmin\backup\$date”

Get-SCOMManagementPack -Name <CompanyName>* | Export-SCOMManagementPack -Path “C:\monadmin\backup\$date”

Get-SCOMManagementPack -Name *Lab* | Export-SCOMManagementPack -Path “C:\monadmin\backup\$date”


# Backup Management packs to E drive

# Set up your path, this example is monadmin\backup

$date = Get-Date -UFormat “%Y-%m-%d”


cd monadmin\backup

new-item -itemtype directory -path e:\monadmin\backup\$date

cd $date

Get-SCOMManagementPack -Name OR* | Export-SCOMManagementPack -Path “E:\monadmin\backup\$date”

Get-SCOMManagementPack -Name *Lab* | Export-SCOMManagementPack -Path “E:\monadmin\backup\$date”



New Unix MP’s for 2016 and 2012R2



If you didn’t catch this (I didn’t), the 2016 Universal Linux Monitoring MP is missing, but is in the 2012R2 bundle

Until the bundle is fixed, don’t forget to grab the Universal Linux Monitoring MP from the 2012R2 bundle


Export the 2012R2 bundle, grab the MP


Import MP into SCOM



If that’s just a tad bit annoying, remember Microsoft wants feedback.

Feedback can be about problems, product specific feature requests, and functionality.


Use the UserVoice website for SCOM (System Center Operations Manager)

There are a lot of good features and feedback on the site.   If you weren’t aware, the product team uses this to prioritize updates to the product.

Temp DB recommendations for SCOM 201x

When someone asks you about TempDB sizing, does your jaw hit the floor?


Time to pull out my handy detective skills



Context & Best Practices 
SQL Server uses the tempdb database to store temporary objects. This can include temporary tables, stored procedures, work tables, and row versions. In short, most changes to user databases are routed through the tempdb database. Increasing the number of tempdb data files enables SQL Server to perform more concurrent operations, by distributing activity over multiple physical files.

Tip Modify properties of tempdb data files to have identical initial size and growth increment.


Support article



The Risk Assessment tool (RAS) states

Increase the number of tempdb files in line with best practice guidance. As a general guideline, in an environment where tempdb is used heavily, the number of tempdb data files should be between 0.25 to 1.0 times the number of physical processor cores. On servers with more than eight physical cores, start with eight data files, and then increase or decrease the number of data files as needed.

Example – 4 core SQL server needs at least 1 TempDB file

Console Errors in the new Active Directory Directory Services MP

New MP released that resolves this – v10.0.2.0 download here


Console Errors in the new Active Directory Directory Services MP



At least it’s not the Security patch issue when you click on Health/State views, right?


In the SCOM Console

Do you get an error when clicking on Authoring Tab, Management Pack Objects, Overrides?


If you are running the 2012-2016 Active Directory Directory Services v10.0.1.0 MP’s, you most likely get an error

“Microsoft.EnterpriseManagement.Common.ObjectNotFoundException: An object of class ManagementPackClass with ID <guid here>”


Unfortunately, the RODC group rule overrides were not referenced to the Discovery MP.

It’s an awesome MP, and I’m thankful for the new AD MP.

Check out Holman’s blog for all the fun and features.


Figure out which management pack has the issue with the ID

To find the offending item from the console error, see this blog.

Blog Summary = Using Ops Manager Shell, export the overrides

get-scomOverrides | out-file d:\monadmin\overrides.txt

Search for your GUID to know the ID and what in SCOM that ID is attached to.

Name              : Microsoft.Windows.Server.2012.AD.DomainController.DRAOutboundBytesComp.Collection.Override.RODCGroup

The highlighted items show a Override for a Rule, named ‘DRA Outbound Bytes Comp’ (compressed)


Now, if you’re impatient like me, and can’t wait for the new sealed MP to fix the console error, here’s how you can fix the MP.

Unseal the three monitoring MP’s

After unsealing the MP, update the RulePropertyOverride(s) for 2012, 2012R2, and 2016 Monitoring management packs, and then import into your SCOM Management group.

MP Viewer How-To, Tool Download


Add Referencing MP to the Rule overrides
For 2012 – AD2012Core! was missing (See Manifest section for AD2012Core MP info)
For 2012R2 – AD2012R2Core! was missing (See Manifest section for AD2012R2Core MP info)
For 2016 – AD2016Core! was missing (See Manifest section for AD2016Core MP info)
The RODC group is created with each version of AD Directory Services (2008, 2012,2016)
In the 2008 MP the overrides exist in the Discovery MP
To correct the 2012, 2012R2, 2016 MP’s, the discovery MP reference must be added to the Rule


Verify overrides in SCOM Console

Click on Authoring Tab, Management Pack Objects, Overrides

overridesconsoleerror  “Microsoft.EnterpriseManagement.Common.ObjectNotFoundException: An object of class ManagementPackClass with ID <guid here>”

Through persistence, you may be able to search for Overrides


In ‘Look For’ bar, type RODC

Hit enter

Verify there are 4 (fyi there are 4 rules per AD version you have installed in your management group)


Remove Sealed AD Monitoring MP’s

Import unsealed MP’s


Verify in Console that overrides show up (No Errors seen)


Click on Authoring Tab, Management Pack Objects, Overrides

In ‘Look For’ bar, type RODC

Hit enter


Verify 16 (4 rules per AD version (2008, 2012,2012R2, 2016;  or 12 rules will display if AD 2008 packs are not installed)

Sample XML for Overrides
<RulePropertyOverride ID=”Microsoft.Windows.Server.2012.AD.DomainController.DRAIntersiteOutBytes.Collection.Override.RODCGroup” Context=”AD2012Core!Microsoft.Windows.Server.2012.AD.RODCGroup” Enforced=”false” Rule=”Microsoft.Windows.Server.2012.AD.DomainController.DRAIntersiteOutBytes.Collection” Property=”Enabled”>

Sizing SCOM 2012R2 and 2016

Many times, the question comes up for Microsoft sizing guidelines for Operations Manager/SCOM.  The Sizing Calculator XLS is a great resource to use to help answer some of the storage and SQL DB questions as it relates to the various features you enable in your environment.

The sizing calculator takes features beyond windows agents to help size SQL and storage needs, as well as management servers.

The SCOM Sizing Calculator XLS from TechNet helps determine capacity and storage needs for 2012 and 2016.  Here is the 2016 System Center SQL matrix
