  • 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 . This mitigation is included out of the box with current deployment of OpsMgr 2007 R2 after system management packs were imported.

  • Blog Post: How to: Reset monitor when closing alert?

    Not something I recommend , one would say I almost regret we did not prohibit closing alerts generated by monitor (especially when auto-resolve feature was used). But recently I learned about some ticketing systems closing alerts where it is unclear if issue was corrected, so I see some necessity to...
  • Blog Post: HOWTO: “restart” monitoring of my environment? (another version UPDATE)

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

  • Blog Post: Where is thy instance monitored and how that affects dependency monitor state?

    This area is rather complex and multiple factors weight in while configuration service makes the final decision, but I will try to provide somewhat simplified, rule of thumbs examples/points to help to make an educated guess while troubleshooting some state issues. I will start with dependency monitor...
  • Blog Post: HealthServiceWatcher alerts and connector.

    Recently I had heard from couple of customers (internal and external) about their trouble with ticketing alerts created from Health Service Watcher.

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

    Some customers not only want to know that health service hosted on the computer was not heart beating (remember, this is way different from our approach to recognize computer down, which BTW solely based on my own opinion, is rather unfortunate attempt to recognize something for what health service watcher...
  • Blog Post: Customizing monitor from sealed MP ("Device Status Check").

    I used Device Status Check monitor in my last post when providing realistic sample of how to define alert settings thru overrides. Unfortunately, and mainly because of override value restriction regarding use of parameter replacement, description of such alert was not able to benefit from property values...

    … Is there anything I can do? Our usual answer was that not really and you need to create your custom monitor while disabling original one.
