Large networks ?

[Craig Skelton]

command_check_interval=60

Two main tweaks make this possible for me. The first is to use a ramdisk for the status log. The second  tweak was to change the ping check to a one packet ping, and each host to max_attempts of 10. The result is a short circuit in ping checks for hosts that do respond.

  Craig,  what is your check intervals set for?  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
