Suppressing service notifications if host fail s

[Parkinson, Alex]

Hi Mott,

I do not know what service checks have been configured for the failed host.
That being said, it may be the case that the failed host was still
responding to ping, whilst the higher level services had failed.

I have found it useful to configure ping as a service check to give a visual
indication of the state of the host - this is duplicate some of the ping
checking of a host.

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_options            d,u,r

Where check-host-alive is:

define command{
         command_name    check-host-alive
         command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 
5000,100% -c 5000,100% -p 1
         }

Thanks for any insight -

Mott
