Distributed nagios problem - service definition not found!

[Jan Scholten]

As far as i know every host and every Service needs to be in the central  
hosts.cfg/Services.cfg (even those, that are not actively checked), so  
they are displayed.

So you need the "Check Host Alive" (which is in the default config named  
PING) to be configured for acdmz-inside-sw2. Passive checks must be  
enabled for this servicecheck active checks should be disabled:
active_checks_enabled 0
passive_checks_enabled 1

You can easyliey see what is missing:

> EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;acdmz-inside-sw2;Check  
> Host Alive;0;PING OK - Packet loss = 0%, RTA = 0.83 ms
> Oct  6 15:02:44 noc-mon nagios: Warning:  Message queue contained  
> results for service 'Check Host Alive' on host 'acdmz-inside-sw2'.  The  
> service could not be found!

You need the service "Check Host Alive" defined for Host  
"acdmz-inside-sw2" which does noit seem to work Have you tried using  
Service Desriptions without Blanks? --> Change to Check_Host_Alive ?


YOU NEED TO DEFINE ALL HOSTS on the Central Server as well (you use  
check_dummy 0 as Host check or set check_poeriod to none)
