Services are critical when printer is offline

[gitbro23]

Hello everyone,

I’m searching for a solution to set the service status to OK when the timeout is reached (because the user switched off the printer)

At the moment all monitored services (such as Pagecount, Trays, Consumables, Ping) are shown as CRITICAL when the devices are offline.

I already configured the thresholds to custom values. But this has no effect when the devices are not reachable.

So, can we set the status to OK when the timeout is reached?

See my screenshot

Thank you very much!

I added an --ignoreoffline switch you can now use. A word of caution though: the printers you use this on will never tell you when they are actually offline. But you knew that already. Download it from the devel branch and let me know if it's working as you expect:

https://github.com/Tylan/check_snmp_printer/tree/devel

I also cannot control the Ping sensor you have. That is not a part of my code. You would have to disable/delete that one or find a way to silence it.

Thank you for quick response! It seems to be, that your new version is based on the new version 2.0.0 And here is a new requrement, that all my plugins are located in the path "/usr/lib64/nagios/plugins" In my case the plugins are located in the path "/usr/lib/nagios/plugins"

So how can I change the default path in my icinga2 configuration?

[Tylan]

Hi -

I already have /usr/lib/nagios/plugins as well as /usr/lib64/nagios/plugins included. The new dependency may be that in 2.0.0 I switched to Net-SNMP versus Net::SNMP. You may need to install those libraries:

Debian:

sudo apt-get install libsnmp-perl

Centos/RHEL:

sudo yum install net-snmp-devel

[gitbro23]

Thank you for your help! After I installed the libraries and replaced your new binary I faced a new crtival message

Update; I switched to SNMP version 2 and now the critical message is gone ;-)

[Tylan]

Awesome! So everything is working as you would expect?

[gitbro23]

Not everything. The Toshiba printers give back a Timeout when using SNMP V2. But its enabled. Not sure if its a firmware bug on the printer.

[Tylan]

Did this work pre 2.0.0?

From the command line can you do a simple snmpwalk against the printer?

snmpwalk -v2c -c public [PRINTER IP] sysName

[gitbro23]

Hi Taylan, I made a test with the old version 1.3.1 Here the snmp V2 check is working fine. See my screenshot

[Tylan]

Hi - can you try raising the timeout a bit? -t 60 for example

Hi - if you add -t 60 to the check_snmp_printer command does it work? I might need to change the default timeout on the new version.

edit: Does it only timeout for when you check consumables?

Yes Yes, it only expires when checking consumables

[Tylan]

Okay, thanks for that info. Let me dig around and see why.

[gitbro23]

Yes im my case its also happening after 60 seconds And its also happening when checking the trays. Only pagecount is working fine.

[Tylan]

And only certain printers, correct? You mentioned Toshiba and @navratilp mentioned Xerox. I have a Xerox printer on prem that works just fine so I will have to poke around a bit more.

Yes, the xerox phaser 7500 printer has a problem, but the HP Color LaserJet Pro m252n printer works correctly

[Tylan]

I made a slight change in hope that corrects the issue. I'll work to enable a debugging switch next but lets see if this fixes it.

https://github.com/Tylan/check_snmp_printer/blob/devel/check_snmp_printer

Grab this version - should have the April 4 date on it

Version 2.0.1 (April 4, 2023)

[gitbro23]

GREAT, Sir! You did it!!

now everything is green! And also the new switch (--ignoreoffline) is working fine!!

Thanks man. Have a great day.

Best regards from Germany!

@navratilp you're using the April 4 version, correct?

I modified some other stuff and there's an April 5 version but it just fixes cosmetic output from your printer:

https://github.com/Tylan/check_snmp_printer/blob/devel/check_snmp_printer

If I run your snmpwalk output through my simulator I retrieve correctly. Granted, my simulator isn't a Xerox Phaser.

Do you have multiple Xerox Phasers? Is this the only one? If you have other Xerox printers, do they work? My last employment had 2 Phasers and they both were very picky but that was just my experience.

Great news! Glad it's all working now for both of you 😄 Marking as resolved and closing out.
