You can have a look at my Nagios plugins, also in this forum.
They are shell scripts; you can adapt their output for your needs.
The current output for Nagios consists of a text message and an exit status 0(OK), 1(WARNING), 2(CRITICAL), 3(UNKNOWN).
After the text message there can be a pipe symbol followed by a performance data sample.
Nagios runs the plugin scripts periodically, with arguments that are typically thresholds for WARNING and CRITICAL.
Nagios displays the output text and reacts on the output status (i.e. raises WARNING or CRITICAL alerts)..
And it records the performance data (in rrd tool). The Web GUI draws perfdata out of it.
For basic monitoring I recommend: check_load5.sh check_disks.sh check_vmem.sh

xynagios
XYNAGIOS(1) User Contributed Perl Documentation XYNAGIOS(1)
NAME
xynagios - adaptor for using Nagios checks with Xymon
SYNOPSIS
xynagios [options --] plugin [options ...]
DESCRIPTION
xynagios runs a Nagios check, and reports its output in a way compatible with the Xymon (Hobbit, BB) monitoring system.
The Xymon test name is taken from the plugin output if it starts with test_name OK|WARNING|CRITICAL|ERROR|UNKNOWN:. Otherwise, the basename
of the plugin filename is used. A check_ prefix is removed for brevity.
OPTIONS
--hostname=host
Report tests as this host.
--strip=prefix
Remove prefix (regexp) from test names. The prefix "check_" is always removed before stripping other prefixes. Useful for trimming down
overly verbose Nagios test names, e.g. "check_postgres_database_size" to "database_size".
--trends
In addition to printing performance data in the status report (suitable for the NCV/SPLITNCV hobbitd_rrd modules), send in a data
report for hostname.trends. This rrd module is more robust.
--help
--version
Print help text and version, and exit.
