  • Blog Post: OpsMgr 2007 R2 - Alert Storm Recognition (possible rule misconfiguration) for SDK alert

    I described the mitigation for alert storm in the one of my previous post .

  • Blog Post: Windows Server 2008 Cluster MP released to web !!!

    In my opinion, Boris did kick a** job driving this puppy out, especially knowing that Windows hotfix is required for its functionality.

  • Blog Post: Clustered Virtual Server 2005 R2 and Operations Manager 2007

    Problem: Monitoring of clustered virtual machines (guests) is unreliable with Operations Manager 2007. Instances of Virtual Machine are not monitored without any apparent reason. Scenario: Having simple wolfpack cluster (implemented thru Microsoft Cluster Services – MSCS) with just a quorum...

    Maintenance mode and cluster became a big issue for most of our customers.

  • Blog Post: “Net view” as diagnostic used when heartbeat is missing

    This all started as question about how “Computer Not Reachable” works. It has been asked in newsgroup and I thought I will help and provide some inside.

  • Blog Post: Cluster resource groups are not monitored! Is there anything I can do?

    Recently I saw some questions about why cluster infrastructure is only partially discovered and it is not monitored when all cluster services are healthy. I replied to some of those questions either internally or at the newsgroup, where I was trying to explain why such health model was possible (so this...

  • Blog Post: UPDATE: MP for monitoring cluster services (MSCS) finally web-released!

    I made a mistake in my post announcing web release of management packs for monitoring of Failover Clusters. I posted incorrect requirements to meet prior importing management packs.
