  • Blog Post: 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 create your...
  • Blog Post: 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...

  • Blog Post: 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 with my day...
  • Blog Post: 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 rights are needed...
  • Blog Post: 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...

    Antivirus Exclusions in MOM 2005 and OpsMgr 2007: Processes: Excluding by process executable is very dangerous, in that it limits the control of scanning potentially dangerous files handled by the process, because it excludes any and all files involved. For this reason, unless absolutely...

      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.

    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 agents that are potentially...
  • Blog Post: 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...
  • Blog Post: 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...

    ***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 see this event a lot in customer environments.  I am not an expert on troubleshooting this here... but saw this post in the MS newsgroups and felt it was worth capturing....

  • Blog Post: 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...
  • Blog Post: 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...

    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...
