[Nagiosplug-devel] check_mrtgtraf: add link to the mrtg graph

[Carlos Peón Costa]

Hi, here is a simple patch to add a link (really any text) to the plugin 
output, so you can click and go to the mrtg graph directly from nagios.

%s|%s %s\n"),

<    Critical threshold pair \"<incoming>,<outgoing>\"\n"));
---
>    Critical threshold pair \"<incoming>,<outgoing>\"\n\
>  -l, --link\n\
>    MRTG link \n"));


Command definition example:

# 'traffic_max' command definition
define command{
        command_name    traffic_max
        command_line    /usr/lib/nagios/plugins/check_mrtgtraf -F "$ARG1$" 
-e 10 -a MAX -w $ARG2$ -c $ARG3$ -l "$ARG4$"
        }

Service example:

# Trafico interno pix_principal
define service{
        use                             generic-service
        host_name                       pix_principal
        service_description             Traf. Int.
        notification_period             workhours
        check_command                
traffic_max!/var/www/mrtg/10.5.1.10_avaya_inc._-_p333t_10_100base-tx_port_22_on_unit_2.log!90000000,90000000!100000000,100000000!<a 
href='/mrtg/10.5.1.10_avaya_inc._-_p333t_10_100base-tx_port_22_on_unit_2.html' 
style='font-size:6pt'>MRTG</a>
}
