Ever need to run a PowerShell command (or script) as a specific ID?

Shout to Tyson Paul for his initial MP with 2016, catch his blog here!
This should help speed up building the MP if you have Visual Studio 2013 or 2015 with Visual Studio Authoring Extensions (VSAE). Read Kevin Holman’s blog if this is new

Quicker method To build the MP as MP fragment, update the following:
get-scomrule | ? { $_.DisplayName -like “System Processor Queue Length*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “Current Disk Queue Length*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “Current Disk Queue*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “Current Dis*k Queue*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Current Disk Queue*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Average Disk Seconds Per Transfer*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Logical Disk Idle Time*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Processor Time Total*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Memory Available Megabytes*” } | fl ID,DisplayName,Name
get-scomrule | ? { $_.DisplayName -like “*Network Adapter Bytes Total*” } | fl ID,DisplayName,Name

Building on Kevin Holman’s MP Fragment Library are additional Uncommon Custom MP Fragments
This is the SCOM Management Pack Fragment Library which includes VSAE Fragments you can use to make SCOM management packs quickly and easily.
V1.0 has two Event Monitors with two state, two or three criteria monitors
Assumptions
Visual Studio, and the VSAE Fragments are installed
Visual Studio has a powerful plugin called VSAE (Visual Studio Authoring Extensions)

If you aren’t familar with MP fragments for authoring, see instructions at: https://blogs.technet.microsoft.com/kevinholman/2016/06/04/authoring-management-packs-the-fast-and-easy-way-using-visual-studio/
Background
A Management Pack fragment is simply a bit of XML, that contains all the “working parts” for a specific workflow….
Several authors have written about the power of fragments since VSAE launched, but the biggest gap I saw can be broken up into two major issues:
•Nobody provided a good “library” of workable MP fragments
•Nobody came up with a VERY simple method to reuse fragments quickly and easily
If you can do a FIND and REPLACE in notepad, you can use this.

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?
https://support.microsoft.com/en-us/help/3200006/system-center-operations-manager-management-console-crashes-after-you
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.
Property : Enabled XmlTag : RulePropertyOverride Rule : ManagementPackElementUniqueIdentifier=78ee983f-268d-0b99-0ca6-b1ca75c46621 Context : ManagementPackElementUniqueIdentifier=0903521d-f768-3d26-a0af-ae52f8c09a29 ContextInstance : Enforced : False Value : false ManagementGroup : SCOM2012R2 ManagementGroupId : 28b70e43-4655-edfc-6127-ff4a72642488 Identifier : 1|Microsoft.Windows.Server.AD.2012.Monitoring/31bf3856ad364e35|1.0.0.0|Microsoft.Windows.Server.2012.AD.DomainController.DRAOutboundBytesComp.Collection.Override.RODCGroup|| 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
Verify overrides in SCOM Console
Click on Authoring Tab, Management Pack Objects, Overrides
“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)
Enjoy!
I’ve also been asked what versions of SQL work with System Center, so here’s references to see what the latest supported SQL version and patch.

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
