check_hpjd_new Nagios Plugin

If you use Nagios to monitor your Jet Direct printers, you may notice that the check_hpjd plugin is a bit useless when it comes to telling you exactly what toner cartridge is low. This forces you to either hunt down the printer's IP address and visit the printer's built-in web interface or you have to hoof it to the printer and see what cartridge is needed.

Not anymore.

About 90% of the time a printer is throwing a warning hissy fit in Nagios, it's because the toner is low or out. I wrote this plugin so that it tells me exactly what toner cartridge needs replaced (color and part number).

To invoke, edit commands.cfg to include the following:

define command{
        command_name    check_hpjd_new
        command_line    php /path/to/check_hpjd_new.php $HOSTADDRESS$ [community string = public] [warn = 10] [critical = 5]
}


The optional parameters (defaults) can be overridden in Version 4.

Use this in your device configs as you would use check_hpjd.

Limitations

This will not work with the old school cable-connected Jet Direct boxes. This will only work on newer printers with the Jet Direct module built in.

• Reduced the use of snmp_get from around 1 billion to 0

Version 3

• Support for pretty much all recent LaserJet products (Possibly more vendors) that are RFC 1514 compliant
• When a cartridge is low, the percent is shown in the Status Information box
• Support added for custom critical and warning levels as percentage. To do this, edit commands.cfg to include something like this to have 10% warn and 5% critical:


define command{
        command_name    check_hpjd_new
        command_line    php /path/to/check_hpjd_new.php $HOSTADDRESS$ public 10 5
}


Version 2

• Kills the plugin at the start if the host can't be found.
• Code cleanup and consolidation
• Added accounting for Processing, Checking, Printing, Jam, Intervention and Fuser keywords in status messages.
• Interface cleanup (No more '-  -' at the end of statuses with exit code 0)
• Code is commented. 
• Added support for older models that advertise cartridge information in hex
