Inspiration

After the number of blog posts increases, it is harder to find a way to locate ones of interest.

The first section lists six posts I consider most important.

The second section is all the posts and very short comments.

Top 6 By Importance [My Prejudiced View]

ITM Database Health Checker

It is common to see a TEMS database [often called EIB] which has problems which cause confusion or sometimes lack of monitoring. This project identifies and documents 50+ advisories which will make things better.

Best Practice TEMS Database Backup and Recovery

The most costly support cases are when a customer does not have a proper backup. One memorable case was after a Storage Access Network device lost power and the most recent backup was over a year ago. I talk to people every day where TSM is used to make copies of the TEMS Databases and that almost every time is insufficient. This post was written jointly by a top L3 engineer and myself. If everyone did this the time to recover would drop substantially.

MS_Offline – Myth and Reality

MS_Offline type situations are extremely weighty and cause problems “at a distance”. For example a recent case with 9545 agents and 22 MS_Offline situations with 5 minute sampling interval has spawned multiple IBM Support interactions. They all come back to this one issue. When Persist>1 is set, the problems are much worse. The blog photo shows a California Condor [VERY LARGE VULTURE] lurking outside a window. Treat MS_Offline type situations as dangerous creatures and you will reduce your risk of injury and pain.

TEMS Audit Process and Tool

This has been available since 2012. It is a perfect way to examine the dynamic impact of workload [Situations, SOAP, real time data requests,etc] on a TEMS. With that knowledge you can make changes to avoid problem conditions. I have one customer who runs this on every TEMS each weekend and if “advisory messages” are present [noted via a non-zero exit code] sends the report to an analyst for review. The rate of emergency IBM Support meetings has dropped to near zero… at least for this area.

ITM Agent Health Survey

This tool provides a view of agents which are online but possibly non-responsive. Cases like this mean that real time data response is slow and partially missing, situations are not running, historical data is not being recorded. These are things everyone should worry about. This identifies the guard dog that doesn’t bark.

ITM Situation Audit

This tool performs a static analysis on all distributed situations and produces report of warning messages. It also reports which situations need TEMS filtering [instead of Agent filtering] which is a prime performance killer. Together with TEMS Audit you can really increase efficiency – reducing the cost of monitoring. This also gets early warning for situations with problems. Surprisingly, 50 of 51,000 situations studied actually had syntax errors – like VALUE instead of *VALUE. Anyway – I expect this to be an important tool over time.
