dear all,I added several new host and service, found the following log.
May 11 09:13:17 nagios nagios: Warning: The check of service 'Total Processes' on host 'test01' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the service...
May 11 09:13:45 nagios nagios: Warning: Check result queue contained results for host 'testp02', but the host could not be found! Perhaps you forgot to define the host in your config files?
