Great !!!

AFAIK, there is no documentation about plugins (for the moment, but it's in the Karl's mind) :-)

The only help you can find, is while running the check itself without
arguments, or most of the time with "--help" option...

<SNIP>
somehost:/usr/local/nagios/libexec$ ./check_ftp
No arguments found
Usage: check_ftp -H host -p port [-w warn_time] [-c crit_time] [-s send]
         [-e expect] [-W wait] [-t to_sec] [-v]

somehost:/usr/local/nagios/libexec$ ./check_ftp --help
check_ftp (nagios-plugins 1.3.0-beta2) 1.8
The nagios plugins come with ABSOLUTELY NO WARRANTY. You may

This plugin tests FTP connections with the specified host.

Usage: check_ftp -H host -p port [-w warn_time] [-c crit_time] [-s send]
         [-e expect] [-W wait] [-t to_sec] [-v]
 Options:
  -H, --hostname=ADDRESS
      Host name argument for servers using host headers (use
      numeric address if possible to bypass DNS lookup).
  -p, --port=INTEGER
      Port number
  -s, --send=STRING
      String to send to the server
  -e, --expect=STRING
      String to expect in server response -W, --wait=INTEGER
      Seconds to wait between sending string and polling for response
  -w, --warning=DOUBLE 
      Response time to result in warning status (seconds)
  -c, --critical=DOUBLE
      Response time to result in critical status (seconds)
  -t, --timeout=INTEGER
      Seconds before connection times out (default: 10)
  -v  Show details for command-line debugging (do not use with nagios server)
  -h, --help
      Print detailed help screen
  -V, --version
      Print version information
</SNIP>

This is the only help i can point you to :)

No i will show you my definition of check_ftp command in my config

<SNIP>
# 'check_ftp' command definition
define command{
        command_name    check_ftp
        command_line    $USER1$/check_ftp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -t $ARG3$
        }
</SNIP>

And i call my check_ftp command definition in my services.cfg like this:

<SNIP>
define service{
       use                             generic-service
       host_name                       somehost
       service_description             FTP
       is_volatile                     0
       check_period  	 	       24x7
       max_check_attempts	       3
       normal_check_interval           3
       retry_check_interval            1
       contact_groups      	       Unix-admins
       notification_interval           120
       notification_period             24x7
       notification_options            w,u,c,r
       check_command                   check_ftp!10!15!20
       }
</SNIP>

where 10 == $ARG1$ (warning threshold)
      15 == $ARG2$ (critical threshold)
      20 == $ARG3$ (timeout)

I know, it's not easy to understand in the beginning, but if you can
understand this time, most of your troubles will be solved right now :)

Hope this helps,

Chris
