Summary
  • The concept - maintaining a server to collect
    only necessary and critical events - not to
    "drown" in huge number of events.
  • Always think ahead, don't wait until problems
    will appear
  • Monitor CPU usage - if its over 90 for more than
    5 min - you've got a problem !
  • Monitor Disk Free Space - if its less than 20 -
    the problem is near.
  • If youve got a problem, think how what can you
    monitor in order to prevent this problem in the
    future.
  • Performance monitor is a strong tool - MOM, makes
    it stronger.
  • Useful tools for capacity planning and budget
    planning.
