The overhead of persisting to RRD one additional scalar attribute (or even a few dozen) is a drop in the bucket on a system that is performing well. In recent releases, you can configure a very small relative change threshold on such an attribute to create an event any time the value changes. -jeff ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
