[Nagiosplug-help] return message for plugins

plugin?
That is part of the output from my plugin.  The output is obtained from
doing a "grep ORA" from Oracle's alert log.  If there is a message, prefix
it with "Warning - ", follow by the output from grep.

To give you an example, if I run the stock check_load command that came with
Nagios I get these message.  I'd like my plugin to show extra messages as
well.

./check_load -w 0 -c 0
CRITICAL - load average: 0.50, 0.40, 0.26|load1=0.500;0.000;0.000;0;
load5=0.400;0.000;0.000;0; load15=0.260;0.000;0.000;0;

./check_load -w 0 -c 1
WARNING - load average: 0.52, 0.40, 0.27|load1=0.520;0.000;1.000;0;
load5=0.400;0.000;1.000;0; load15=0.270;0.000;1.000;0;

./check_load -w 1 -c 2
OK - load average: 0.59, 0.42, 0.28|load1=0.590;1.000;2.000;0;
load5=0.420;1.000;2.000;0; load15=0.280;1.000;2.000;0;
