SCOM: Dashboards are blank when opened in a particular console

It’s always the bugs you come across when you are trying to do something else that can be the most frustrating. Today while creating some dashboards for one of my clients the views returned blank after saving them.

I then had a look at the SQL built in dashboards to see how widespread this issue was and had the same results. The dashboard pane was blank and the tasks also did not display.

First I tried restarting the console with the /clearcache command and this usually address display issues and had the same result.

I then tried a console on a different server and then I tested using the web console both loaded the dashboards properly . So I was dealing with a server issue or a profile issue.

A bit of research suggested that sometimes this problem can be caused by a corrupt .net installation. As this requires change approval in order to address I first tested the profile option by logging on to the same server, where I experienced the issue with another user account. This time the dashboards loaded correctly so it’s probably not a .net issue.

Considering that /clearcache didn’t work I wanted to first try and remove the momcache.mdb cache file located in C:\Users\<user account>\AppData\Local\Microsoft\Microsoft.EnterpriseManagement.Monitoring.Console in order to test all options before recreating the user profile.

After deleting momcache.mdb and re-opening the console all the dashboards now loaded correctly.

SCOM 2012 R2: Support for SQL Server 2008 R2 SP3

Over at the MS SCOM engineering Blog it’s been newly released that SCOM 2012 R2 now supports SQL Server 2008 R2 SP3.

There is a catch though see below for what to be aware of:

Issue: Fresh Install of SCOM 2012 R2 on SQL 2008 R2 SP3 will not work
Workaround: Deploy SCOM 2012 R2 on to SQL 2008 R2 SP2 and after installation upgrade the DB to SQL 2008 R2 SP3

SCOM: Unable to view overrides in Authoring pane when no scope is selected.

An odd issue I encountered today at one of my customers that has recently completed a migration to SCOM 2012 R2, when trying to open the overrides node with no scope selected I got the following error “An object of class ManagementPackClass with ID <GUID Removed> was not found” and then the view shows 0 overrides until the console is reopened with a /clearcache.

Turns out this error is caused by having an override that references a class that no longer exists, in order to track it down you first have to access the overrides which you can no longer see unless you do the following:

1. Export your overrides to text file using poweshell by running get-scomoverride | out-file c:\SCOMOverrides.txt
2. Search the output text file for the GUID which was in the original error “An object of class ManagementPackClass with ID <GUID Removed> was not found
3. The GUID will appear on a line labeled Context, below that one look for a line labeled Identifier, In my case it looked as follows “Identifier: 1|Windows.Operating.System.Custom.Monitors”
4. Generally this is enough information to identify which management pack needs to be deleted if it is not then continue to step 5
5. In SQL run the following query, remebering to edit it for your Identifier, against your operationsmanager database select * from ManagementPack where ManagementPackSystemName like ‘Windows.Operating.System.Custom.Monitors’
6. Once you have identified which management pack is causing your issue it needs to be deleted, once the new configuration is processed you will be able to see your overrides again.
