Re: [Nagios-users] Suppressing service notifications if host fails
Hi Marc -
Thanks for the quick response. Our check_command *seems* to be properly
configured. it uses a check-host-alive plugin, and it DID return a
CRITICAL state, but looking more closely at the logs, it seems like it
wasn't reported as critical until some 4 hours or so after all the
services reported themselves as CRITICAL. Don't individual services
check on the health of their host? Why wouldn't it report the host as
down until so much later?
All our hosts are defined as:
check_command check-host-alive
max_check_attempts 10
notification_interval 120
notification_period 24x7
notification_optionsd,u,r
Where check-host-alive is:
define command{
command_namecheck-host-alive
command_line$USER1$/check_ping -H $HOSTADDRESS$ -w
5000,100% -c 5000,100% -p 1
}
Thanks for any insight -
Mott

if you have a properly configured host check_command that returns
CRICITAL or UNREACHABLE when the host is down.

That's determined internally by Nagios based on the 'parents' directive
for each host. [/edit]
