How to diable check-host-alive



I’ve got a fresh install of Nagios 3.0.6.
Most of my servers I can’t ping so Nagios says the host is DOWN. Is it possible to global disable check-host-alive so my hosts become UP. I already tried to remoe check-host-alive in the configuration but then the hosts are status PENDING.

Hope you can help me out.

Kind Regards,


Nagios somehow needs to know is host is up or down.
If ping is no solution to check-host-alive, then any other plugin can be used for check-host-alive, for example check_snmp. You just need to configure that in command definitions of your plugins.
If you don’t want to use host-check-alive at all then you could set the host with passive-check-enabled and set initial_state as up. Then never submit any result for that host to Nagios and fake Up state is always on.
