Bill Anton digs into the SSAS Flight Recorder:
During a recent engagement involving an Analysis Services health assessment, one of the things I noted was that the Flight Recorder was enabled. During the post-assessment review with the client, where we walked through the report and recommendations, I quickly explained what the Flight Recorder was, why it should be disabled (answer: never used, wasted resources, etc), and that disabling it would not produce a noticeable performance gain – the recommendation was mostly out of habit.
Bill’s answer is to build custom performance monitoring.
