Normalizing printer supply names -

[furicle]

Zabbix 7.4 on Alma 9

I'm monitoring a number of network printers using the Universal Printer template and snmp

It works well, but different manufacturers have different names for their supplies. So when I try to build a dashboard for just the supplies, I end up with multiple entries like

• "Remaining Black Toner Cartridge S/N:CRUM-123456789"
• "Remaining Black Toner" and
• "Remaining Black Cartridge"

depending on manufacturer.

I mucked around a bit and tried to put regex in preprocessing on the five item prototypes in the template of universal printer

(?i)^(.*?)\s*(?:toner\s*)?(?:cartridge|module|s/n).*

replace with

 \1 Toner

but that doesn't seem to be working. Feels like I'm in the wrong spot?

Where do I insert the regex to standardize things?

(?i)^(.*?)\s*(?:toner\s*)?(?:cartridge|module|s/n).*
/ Delimiter must be escaped with `\`
Not all of your examples match https://regex101.com/r/bk4Tuq/1

But in general, item value preprocessing is the correct place to extract something from aqcuired value and modify it...

Thanks for the feedback, I've fixed escaping the \
The 'remaining' from my example is in the item itself, so that's ok not to match.

Still not working, even cartridge vs toner. Haven't figured out what I'm missing.
