The script is logicaly called check_prtdiag.
It's 100% config-file based, massively using Perl regular expressions and logic, as prtdiag output is very different from one system to another.

Without any parameter, check_prtdiag will launch a prtdiag -vcommand and parse its output.
For testing purpose, you can use the -v flag to get more verbose output (on STDERR), or use the f <file>option to use the content of the specified file as input.

See check_prtdiag.txt for details about configuration file format.

Edited 2008-12-05 - release 1.10 :
You can now specify an alternate config file location using the -c <file> option.
The prtdiag command is no more mandatory when using the -f <file> option for testing purpose.
The Unrecognized escape \s passed through warnings should be gone.
Added tests for SunFire V210 in the sample configuration file.

Edited 2009-01-08 - release 1.11 :
Corrected exit codes on CRITICAL and WARNING statuses.
Thanks to Jonathon Weiss for finding this bug.

Edited 2009-01-08 - release 1.12 :
Release 1.11 was crappy.
Thanks to Eric Pearce for feedback.
