[Nagiosplug-help] Nagios plugin Usage

[Bryan Bateman]

I am a novice but I have found that the libexec directory of nagios contains
the check commands.  Simply execute the command with --help appeneded and
the usage information is displayed.
 
I also noticed that the way you were showing the command was the way it is
expressed in the services.cfg file.  This is an alias to the actual command.
The actual command that is used can be found in the checkcommand.cfg file.
You will have to cross reference between that and the information obtained
from the command line to determine what is really going on.

This plugin tests the HTTP service on the specified host. It can test
normal (http) and secure (https) servers, follow redirects, search for
strings and regular expressions, check connection times, and report on
certificate expiration times.
 
Usage: check_http -H <vhost> | -I <IP-address> [-u <uri>] [-p <port>]
                  [-w <warn time>] [-c <critical time>] [-t <timeout>] [-L]
                  [-a auth] [-f <ok | warn | critcal | follow>] [-e
<expect>]
                  [-s string] [-l] [-r <regex> | -R <case-insensitive
regex>]
                  [-P string] [-m <min_pg_size>:<max_pg_size>] [-4|-6] [-N]

    Append a port to include it in the header (eg: example.com:5000)

   (Note that this still does an HTTP GET or POST, not a HEAD.)
 -M, --max-age=SECONDS
   Warn if document is more than SECONDS old. the number can also be of
   the form "10m" for minutes, "10h" for hours, or "10d" for days.

 -L, --link=URL
   Wrap output in HTML link (obsoleted by urlize)
 -f, --onredirect=<ok|warning|critical|follow>
   How to handle redirected pages
 -m, --pagesize=INTEGER<:INTEGER>
   Minimum page size required (bytes) : Maximum page size required (bytes)

 -v, --verbose
    Show details for command-line debugging (Nagios may truncate output)
This plugin will attempt to open an HTTP connection with the host.
Successful
connects return STATE_OK, refusals and timeouts return STATE_CRITICAL, other
errors return STATE_UNKNOWN.  Successful connects, but incorrect reponse
messages from the host result in STATE_WARNING return values.  If you are
checking a virtual server that uses 'host headers' you must supply the FQDN
(fully qualified domain name) as the [host_name] argument.

Hi Sir/Madam,
 
Can i know how to use plugins which needed in "check_command" in
"services.cfg"? 
 
For check_ping, i follow the given sample config which use
"check_ping!100.0,20%!500.0,60%" and it works well.
For the others plugin I just use "check_http", "check_pop", "check_ftp",
"check_smtp" 
 
Must we add some config at the behind of the plugin command? Example as
below
 
check_ping!100.0,20%!500.0,60%
 
Currently i am still finding out the way to use plugin. 
 
Thank You...
