I'll be the 'expert' for an Ask The Expert session at the GroundWork Open Source booth (booth 501) at LinuxWorld Expo 2007 this afternoon from 4-5pm. If you are in the Bay Area, come by and say hi! Plenty to see besides me - Cacti, rrdtool, nedi, smokeping, and many others are also represented.
Also, from 6-7pm I'll be at the Monitoring BOF (BOF5), whereever that is held at Moscone Center.
