  You may notice that there are actions you might want to take on an agent, that are grayed out and not available in the console. There actions might include: Change Primary Management Server Repair Uninstall See the below image for an example:   This is caused by a flag in the database, which has…

Tuning tip: Do you have monitors constantly “flip flopping” ?

  This is something I see in almost all clients when we perform a PFE Health Check.  The customer will have lots of data being inserted into the OpsDB from agents, about monitors that are constantly changing state.  This can have a very negative effect on overall performance of the database – because it can…

The new and improved guide on HealthService Restarts. Aka – agents bouncing their own HealthService

I have written many articles in the past on HealthService restarts.  A HealthService restart is when the agent breaches a pre-set threshold of Memory use, or handle count use, and OpsMgr bounces the agent HealthService to try and correct the condition. The Past: Here are a few of the previous articles: http://blogs.technet.com/kevinholman/archive/2009/03/26/are-your-agents-restarting-every-10-minutes-are-you-sure.aspx http://blogs.technet.com/kevinholman/archive/2009/06/22/health-service-and-monitoringhost-thresholds-in-r2-how-this-has-changed-and-what-you-should-know.aspx   Generally…

29106 event on RMS – Index was out of range. Wait. What?

Was working with a customer on this one – figured it might help others. Saw a lot of these VERY SPECIFIC 29106 events on the RMS, specifically with the text:  System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.   Here is the full event: Event Type:     …

Keep your management pack names SHORT in SP1!

I have seen this twice now… so I will blog about it.  It seems to be rare in the wild, but it will completely cripple a management group when this occurs.  So beware SP1 users!   This article does not apply to R2.  This is only an issue in OpsMgr 2007 SP1.   When you…

Fixing troubled agents

Sometimes agents either will not “talk” to the management server upon initial installation, and sometimes an agent can get unhealthy long after working fine.  Agent health is an ongoing task of any OpsMgr Admin’s life. This post in NOT an “end to end” manual of all the factors that influence agent health…. but that is…

R2 – Improved Agent Proxy Alerts

Here is a nice add in R2:  When we give you the old “agent proxy alert”, we now tell you the name of the Agent that needs agent proxy enabled, and resolve the name of the object type that it was bringing in:   Nice improvement.  I enable agent proxy for SQL1CLN2 and get on…

Are your agents restarting every 10 minutes? Are you sure?

**Updated 12-21-2009 This post is OLD, and the way this process works has changed. Please see the updated post at: http://blogs.technet.com/kevinholman/archive/2009/12/21/the-new-and-improved-guide-on-healthservice-restarts-aka-agents-bouncing-their-own-healthservice.aspx

The Cluster Service will automatically restart itself

Something I ran across with a customer. There aren’t many situations where service recoveries run automatically in Microsoft MP’s, but this is one case where they do.  The cluster service running is critical to a healthy cluster.  In the current cluster MP, the service monitor for the cluster service will automatically start the cluster service…

Getting and keeping the SCOM agent on a Domain Controller – how do YOU do it?

I’d like to hear some community feedback on this….   In OpsMgr – deploying a SCOM agent to a DC often presents companies with a bit of a challenge.  The reason is – in order to install software to a DC and manage it – we need rights on the DC to accomplish this.  These…

Agent Pending Actions can get out of synch between the Console, and the database

When you look at your agent pending actions in the Administration pane of the console…. you will see pending actions for things like approving a manual agent install, agent installation in progress, approving agent updates, like from a hotfix, etc.   This pending action information is also contained in the SQL table in the OpsDB…

A report to show all agents missing a specific hotfix

This is a continuation of my previous post on determining which agents are missing a hot-fix: How do I know which hotfixes have been applied to which agents- I wrote up a report that allows you to paste in a KB article number into the report as a parameter, and then it will show all…

Which servers are DOWN in my company, and which just have a heartbeat failure, RIGHT NOW?

          In OpsMgr 2007, when a agent experiences a heartbeat failure, several things happen.  There are diagnostics, and possibly recoveries that are run.  Alerts, and possibly notifications go out. But what happens if my Operations team misses on of these alerts?  What can I do to "spot check" agents with issues?…

Agent Proxy alerts – finding the right machine to enable agent proxy on using a custom report

Certain types of agents need the agent proxy setting enabled.  These are documented in various guides… such as Exchange Active Directory, Cluster nodes, etc… However, sometimes, we still get alerts that Agent Proxy needs to be enabled for a HealthService.  The problem is… the Alert often doesn’t tell us which agent needs this enabled!!! Here…

How do I know which hotfixes have been applied to which agents?

***UPDATE***  A new hotfix has been released, which is a simple updated management pack…. which fixes the Patchlist table to include all hotfixes, and cleans up the formatting.  I recommend you get it and install it on your SP1 environments. http://support.microsoft.com/kb/958253  ————————————————————————————-  As more hot-fixes are applied to our OpsMgr 2007 SP1 environments…. how can we…

Event ID 2115 A Bind Data Source in Management Group

Installing the OpsMgr 2007 agent on an ISA 2004 or ISA 2006 server

When you want to manage and monitor an ISA server, you need to install the OpsMgr agent. However, there is no guide published for the OpsMgr 2007 ISA MP…..   It comes with the MOM 2005 guide.  In ISA, there was a system policy which you could enable for MOM.  This would open the necessary ports…
