nagios url checks

the check url with check_http results in warning in the web interface:

	
FOO.com
	
Notifications for this service have been disabled
	UNKNOWN 	01-19-2012 17:12:04 	0d 0h 0m 9s 	1/4 	check_http: Warning threshold must be integer - /index.jsp 


the command definition is set to this:

'check_url' command definition
define command{
        command_name    check_url
        command_line    $USER1$/check_http -H $HOSTADDRESS$ -u $ARG1$ -w $ARG2$  -c $ARG3$
        }


the service definition is set to this:


define service{
        use                             local-service         ; Name of service template to use
        host_name                       localhost
        service_description             foo.com
        check_command                   check_url!foo.com!/index.jsp!5!10
        notifications_enabled           0
        }

the command I am trying to use does work on the command line: 

[root at mlb-nag ~]# /usr/local/nagios/libexec/check_http -H foo.com -u /index.jsp -w 5 -c 10
HTTP OK: HTTP/1.0 200 OK - 143385 bytes in 0.161 second response time |time=0.161110s;5.000000;10.000000;0.000000 size=143385B;;;0



The reason I am taking this approach is that the URL is a large load balanced web environment with over 200 web servers and the load balancer is set to not respond to pings. If I use a traditional host check, the host is reported as 'down' tho the URL check usually works if handled in this manner. I am attempting to monitor the URL in such a way that the host check is not reported as down.


thanks

tim
