In June 2007, we posted OpsMgr by Example: Configuring Baselines (http://ops-mgr.spaces.live.com/blog/cns!3D3B8489FCAA9B51!183.entry), which discussed working with the baselines in the Exchange 2003 management pack for OpsMgr 2007.
Microsoft released the most recent update to the Exchange 2003 management pack 8/21/08, available for download at http://www.microsoft.com/downloads/details.aspx?FamilyId=9FF454F4-6D34-4FB9-9E0B-F5B68C6EDC4F&displaylang=en&displaylang=en. This newest version of the MP lowers the sensitivity of Self Tuning Threshold (STT) rules and monitors, increasing the threshold at which the monitors alert.
In addition, the following Self Tuning Threshold monitors were disabled and replaced with static "consecutive samples over threshold" monitors:
- MSEchangeIS\RPC Averaged Latency
- MSExchangeIS Mailbox\Send Queue Size
- SMTP Server\Remote Retry Queue Length
- SMTP Server\Local Queue Length
- SMTP NTFS Store Driver\Messages in the queue directory
- MSExchangeIS Transport Driver\TempTable Current
- SMTP Server\Remote Queue Length
For additional information, check the "How to Configure Self Tuning Threshold Monitors" section of the management pack guide, OM2007_MP_ExSrvr2003.doc. This section describes how the STTs work.
We see this change in the Exchange 2003 management pack as a logical step forward, and were glad that community sites like this one are having an impact in the product evolution.
