Pro-Active Problem Avoidance and Diagnostic Collection
Although some problems may be unforeseen, in many cases problems may be avoidable if signs are detected early enough. Additionally, if an issue does occur, it is no use collecting information about that issue after the event. For information on proactive preparations and diagnostics (such as testing and collecting baselines for comparison purposes), see the following notes:
<Document 1477599.1> Best Practices Around Data Collection For Performance Issues
