I just setup Nagios and I am currently monitoring 60 services ... the scheduling queue was showing less than %100 for the past 5 minutes until I changed my normal check interval from 60 seconds to 120 seconds? Some services (maybe 5-10 out of 60) were not being checked for say 10-20 minutes or so? Seems strange. I thought I would check to see if you had to do any tweaking to get yours to run %100 below your normal check interval setting. -- Blake --- Craig Skelton <<A href="mailto:cskelton@rackforce.com">cskelton@rackforce.com</A>> wrote: > I'm currently monitoring 700+ servers with 2200+ > services on a single nagios system.
