Hi Giorgio
THANK YOU.
What an idiot I am. I copied a load the stuff over from the old server
but of course, I had not copied over the printer-service settings, as a
quick check I changed it back to generic-service and it's started to
work straight away, as soon as you said that I realised what I have
done. I've tested and had the services go onto the second attempt which
is when they put it off for a week, and it's worked.
One last time. THANK YOU, I could kiss you I'm so happy!!!!!!
Stephanie

Hi
I'm on mobile so I can miss something.
Can you show me the printer-service template definition?
Ciao,
Giorgio

Hi.
I'm ok with Nagios, but I'm not linux guru so treat me gently :)
I have reinstalled Nagios onto a new Server it was running on a very
old pc that had hardware issues. So I've now re-installed it on a Dell
R300 with 16 Gig of memory complete overkill but it's what I had
available.
I am running Nagios Core 3.2.3 on Fedora Linux.
[root at nagios]# uname -a
Linux nagios.***.*** 2.6.35.13-91.fc14.x86_64 #1 SMP Tue May 3 13:23:06
UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
I have problems with checking services I have at the moment 107 devices
on it printers and switches, (the old bashed up PC had around 300
devices on it and worked fine before the hardware died). Anyway I am
trying to monitor services and for all the switches it seems fine, but
for all of the printers it's not working. Automatically so I am
wondering if i've done something wrong but I cannot work out what is
wrong it all appears to be fine, please see below. But when I try
monitoring services it will start and for the odd printer work fine but
the next printer in the list it will not work for and what happens is it
check the service once and it's fine but then when it comes to do the
second check on either the check_ping or check_printer service it either
disables checking the service or moves the date forward a week for the
next check.
I'm stuck as to why these services are either not being checked or put
forward to only check them in a weeks time.
All my switches that work are in a group called generic-switch
I've tried putting half a dozen of the printers into generic-switch
instead of novell-printer and they have exactly the same results so I
don't think it's got anything to do with that. Any help would be
appreciated.

In the nagios.log file after trying to run a service the second time it
shows up as below:-
Warning: Check of service 'PING' on host 'ANS-ACCOUNTS01' could not be
rescheduled properly. Scheduling check for next week...
[1305715325] Warning: Check of service 'Printer Status' on host
'ANS-ACCOUNTS01' could not be rescheduled properly. Scheduling check
for next week...
So using this example:-
printers.cfg includes
define host{
use novell-printer
host_name ANS-ACCOUNTS01
alias Dell Colour Laser 5110cn
parents LGH-242
icon_image printer.png
statusmap_image printer.gd2
address ***.***.***.***
}
define hostgroup{
hostgroup_name LGH-NOV
alias *** - Novell Printers
members **,ANS-ACCOUNTS01,**,**,**,**,**
}
define service{
use printer-service
host_name ANS-ACCOUNTS01,**,**,**,**,**
service_description Printer Status
check_command check_printer!
normal_check_interval 2
retry_check_interval 1
}
define service{
use printer-service
host_name ANS-ACCOUNTS01,**,**,**,**
service_description PING
check_command check_ping!3000.0,80%!5000.0,100%
normal_check_interval 5
retry_check_interval 1
}
In the templates.cfg file:-
define host{

THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
}
define host{

this host template
use generic-host ; Inherit these
default values
check_period 24x7 ; By default,
