Re: New to writing plugins.

Dear Ladies and Gentlemen,

Writing Netsaint/Nagios plugins is documented at

 http://netsaintplug.sourceforge.net/doc/developer-guidelines/book1.html

and possibly at the Nagios site also.

Please note that this is a really a superset of what you need to know to
write plugins because this documents target audience is plugin
developers who must address standards and portability (if not style). 
These matters are simply irrelevant if you want a qucik and dirty check 
of _your_ application.

The fact that one can write _easy_ and _useful_ plugins in whatever
language you like [ provided that it has bindings to POSIX 1003.1
(probably a worong and fancy way of saying that you need to be able to
call the exit system call)] is one of the outstanding things about 
Netsaint.

All your plugin must do is something like :-

#!/usr/bin/perl -w

use strict ;
use utils qw(%ERRORS)

# initialise

# check the service 

my $ok = &some_complicated_business_logic(@a_lot_of_parameters) ;

exit $ERRORS{OK} if $ok ;
exit $ERRORS{CRITICAL} ;

It is that easy.

As another writer said, the plugin-scripts directory has lots of real 
sample that should help you get started.

Yours sincerely.

continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
