I've noticed that I often collect data to diagnose a problem by:

  1. Causing the problem to happen, then
  2. ls -lrt/var/log,

  5. Read, wonder, think, guess, test, repeat as needed.

I'm sure that most of you have a few canned methods (like the above) for gaining information.

Where is a good place to share these tips?
