no active host checks just active service checks (few passive too) To disable change the host definition/template option active_checks_enabled 0 Host checks are done on demand when any service returns a critical state (maybe a non-OK state I can't remember). This is default nagios functionality

Re: [Nagios-users] Ways and tweaks to make nagios more efficient. load average on monitoring host edging up.

I use service deps. Most of my services are nrpe checks and I create a dep on nrpe. If a check comes back critical (or which ever state you choose to execute the dep) it does an nrpe check, if nrpe returns critical (or whichever state you choose) it stops executing the services dependant on nrpe

[Nagios-users] Ways and tweaks to make nagios more efficient. load average on monitoring host edging up.

I set up my nagios system to monitor 256 odd nodes each with about 6 services (direct and NRPE). It is working fine but my load averages have started edging upwards. Not critical yet but I wanted some tips to make things more efficient and see if there are things I might have done ineffeciently. O
