Changing check_http.c

[Andrew Davis]

My checkcommands.cfg has an "check_http" entry that looks like this:

    # 'check_http' command definition
    define command{
            command_name    check_http
            command_line    $USER1$/check_http -I $HOSTADDRESS$ $ARG1$
            }


My services.cfg has a correlating entry that looks like this:

    ## HTTP - alternate URL suffix
    define service {
            host_name                       server
            service_description             HTTP
            check_command                   check_http!-p 9090 -u /proteus
            ~
            action_url                     
    /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
    }


When I run this at the command line, I see:

    /usr/local/nagios/libexec/check_http -I server -p 9090 -u /proteus
    HTTP OK - HTTP/1.1 301 Moved Permanently - 0.002 second response
    time |time=0.002480s;;;0.000000 size=577B;;;0


So far, so good, but what I really want to see is the URL in the output. 
Obviously, looking at the test, I can combine the server name, port, and 
URL suffix to figure out the URL. Unfortunately, while I'm good at shell 
scripting and perl, I'm not a C guy and the http test (check_http) is 
written in C. Anyone know what I would change in check_http.c to have 
the output show something like this:

/usr/local/nagios/libexec/check_http -I server -p 9090 -u /proteus
HTTP OK - HTTP/1.1 301 Moved Permanently *http://server:9090/proteus* - 
0.002 second response time |time=0.002480s;;;0.000000 size=577B;;;0

Its one thing to be told that my website is down, but when I'm runnng 
multiple copies of Apache, Tomcat, and custom apps and hosting perhaps 
20 different URL's and port combinations, it would be a LOT more 
convenient if Nagios showed me which URL was failing in the output of 
the test.
