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.

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 automate the action of resetting monitor…

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.

Dynamic alert settings for monitor which never had any (done thru overrides)

Tim from QuickenLoans contacted me and wanted verification about ability to use AlertMessage override (discussed in my previous post) with unit monitor for SNMP network device.
