Ah, thank you, Jim. I see what you mean. That does the trick for the 
time schedule and i now let cron
make the scheduling. But now i got one other problem, that is:

Before a particular webapplication check can start, the associated host 
must be checked to be up.
Only if the host is OK, the webapplication-check shall execute. So how 
can i do this ?

I would like to add a sequence into my test script, which asks nagios 
someting like

"What status have you recently determined for host abc?"

I could of course check the host status directly from my script, but it 
sounds much better to me, if i could
ask nagios directly for the status information. So is there any 
possibility to query nagios for information ?
I have looked into the CGI scripts documentation. These scripts seem to 
return high level information but
this information is allready layouted. What i am missing here is 
something like raw data query,  which i can ask
to give information  e.g. as an XML-data stream for further processing  
in my monitoring application.

Does something alike exist ? Maybe as an add-on to nagios?
regards, hussayn
