HP Color LaserJet 2600N - Toner percent / Left|Printed pages

[tkempken]

Hi Guys,

this script is a workaround to get the following values over HTML Code from Webpanel which are not inside of SNMP MIB:

- Toner Catridge left
- Estimated Pages Remaining
- Pages printed with this supply

The script get the webpage with wget and grep´ to requested values.
You have to change the language on top of script.

Requirements: Linux, wget, cat, grep, php (command line)

Command: ./get_data.php
Output: rest_toner_black:99 rest_toner_magenta:99 rest_toner_cyan:99 rest_toner_yellow:99 left_pages_black:2483 left_pages_magenta:1989 left_pages_cyan:1989 left_pages_yellow:1989 printed_pages_black:17 printed_pages_magenta:11 printed_pages_cyan:11 printed_pages_yellow:11

You have to create a new "Data Input Method"

Name: "HP Color LaserJet 2600n"
Input Type: "Script/Command"
Input String: "/path/to/get_data.php"

with following output fields:

rest_toner_black
rest_toner_magenta
rest_toner_cyan
rest_toner_yellow
left_pages_black
left_pages_magenta
left_pages_cyan
left_pages_yellow
printed_pages_black
printed_pages_magenta
printed_pages_cyan
printed_pages_yellow

It's not comfortable and not beautiful but it's a good workaround

Additional Config for German Interface

and a screenshot

[tkempken]

I suspect you are from Germany?

Well... my first try failed because I never bothered to read the instructions. I did ./script.php my_ip_addr

As for my second try, ... nicht schlecht!

[jweinraub@intranet ~]$ ./get_data.php
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pgsql.so' - /usr/lib/php/modules/pgsql.so: cannot open shared object file: No such file or directory in Unknown on line 0
rest_toner_black:59 rest_toner_magenta:43 rest_toner_cyan:43 rest_toner_yellow:43 left_pages_black:2518 left_pages_magenta:1324 left_pages_cyan:1324 left_pages_yellow:1324 printed_pages_black:1750 printed_pages_magenta:1756 printed_pages_cyan:1756 printed_pages_yellow:1756

I don't know why I get this warning. I don't know if this is due to your script or my PHP configuration since I recently upgraded to PHP5, compiled from source since RHEL 4 does not support PHP5 just yet .

I have several of these printers. So I wonder if it is possible to make this work with them all. Do I need to use a variable for $ip?

Or do i need several instances when I graph these. Another thing I use here is nagios. I wonder if it is easy to make this into a nagios plugin so i can get warnings when the ink is low.

Thanks! Danke schön!

Try this script with: ./script.php my_ip_addr

This script download a temporary webpage with name status_192.168.1.2.htm for each printer...
So we won't get in any problems regarding "parallel polling"...
My concept was only for my single printer at home
After running it also remove the temp page...

I hope u understand my thoughts...

@PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pgsql.so'

I think you have define some libs of postgresql inside of /etc/php.ini or so
If you don't need it you also can remove package php-pgsql

Otherwise add

Code: Select all

error_reporting(0);

after

Code: Select all

#/usr/bin/php -q

<?php

Sometimes it's better to close the eyes

What are the steps needed to start polling this? I added the script and descriptions into cacti, but how do i add the host?

[tkempken]

I think it depends what you want to do...
If you have got more printers I would suggest to create a data and graph template.

For my single printer it would be a kind of 'oversized'...

I written down my steps and create a smart word document...
It was fast and not the best english but i hope you understand it...

script for nagios

I think you can implement it like this:

Copy it to your directory where check_plugins are located...

define command{
command_name check_hpcl2600n
command_line $USER1$/check_hpcl2600n.php $ARG1$ $ARG2$ $ARG3$
}

arg1 = ip
arg2 = warn level (percent)
arg3 = crit level (percent)

Code: Select all

./get_data.nagios.php 192.168.2.100 80 43
TONER OK B:99 M:99 C:99 Y:99

TONER WARNING B:99 M:99 C:99 Y:99
TONER CRITICAL B:99 M:99 C:99 Y:99

maybe it works for you

[jweinraub]

great thanks! i forgot to make notification on this so i forgot to check. i will work on this now. i will let you know my results. your english is very good, i am sure much better than my german!

[jweinraub]

reinstalling pgsql fixed that problem!

[root@intranet libexec]# ./check_hpcl2600n.php 10.1.3.6 80 43
TONER WARNING B:54 M:43 C:43 Y:43

as for the warning/critical, shouldn't it be the other way around?

100% is when it is full, so

[root@intranet libexec]# ./check_hpcl2600n.php 10.1.3.6 40 20

I think might be more appropriate in my case, but thanks for the advice!

[tkempken]

hi

if toner level of any catridge is less than 80 so it set the status to warning.
but if it's less!!! than 43 then it's critical?

i think it's working fine?

what do you mean?

[jweinraub]

it shows percentage remaining. so if it is less than 40% remaining it is a warning, meaning i will check inventory to be sure i have toner in stock.

if it is 20% it is time to examine for print quality and be prepared to replace the toner.

80% remaining is still brand new to me, so it will flag error too soon.

[tkempken]

oh lol... sorry
i understand... that was only a nasty example by me...

i tested it with some values

that's the reason why you can define your own warn and crit level for each printer or globally inside of commands-file

what's about cacti? does it works for you?

[jweinraub]

i have not tried. i been very busy today actually. though the fact nagios should be running smoothly now so that is main concern.

cacti i use to gather statistics on toner use, mainly to determine or justify the need for a more expensive printer.

As you can see here, I go through a lot of ink on this one particular printer.

i will get back to you monday when i finish cacti (and rest of nagios for the remaining printers).

thanks!

[tkempken]

oh... that's really frequently...

but this is another printer, or?

okay... have a nice weekend

[jweinraub]

hmm

this is odd on nagios page:

Yes, this is HP 1320n, general use printer.

Danke, Haben Sie eine gute Wochenende auch!

(i hope my grammar was good)
