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. The update of your host status check results will only happen when a host check is intiated. If a service on that host never goes into a non-OK state it will never execute the host check. If it does it will execute a host check, if the host is down it will stop executing service checks, and use your host check_interval to continue executing host checks, when the host returns to an OK state service check processing will begin again. if you want to have a host alive check that does both ssh and ping i would suggest writing a wrapper plugin which first executes check_ssh and upon failure executes a ping: #!/bin/sh hostaddress=$1 check_ssh $hostaddress if [ $? -eq 0 ]; then echo "ssh up = host up" exit 0 else check_ping $hostaddress fi On 1/28/09, Rahul Nabar <rpna...@gmail.com> wrote: > On Wed, Jan 28, 2009 at 1:32 AM, Kyle O'Donnell > <kyleodonn...@gmail.com>wrote: > >> I use service deps.
