help with template oid issue UPS-MIB / MikroTik

[[email protected]]

Hi,
I'm trying to build a general template to monitor the UPS values I can get from a mikrotik router. The routers have a USB port that can talk to certain UPS's and report back data via UPS-MIB.

My challenge is that if I do a query on tik-a with the following OID, it works.
OID: .1.3.6.1.2.1.33.1.4.4.1.5.6
I get a valid result.

if I send the same OID to tik-b, i get an error
"No Such Instance currently exists at this OID"

If i remove the .6 at the end (go up one level) and run a manual cli
snmpwalk on either tik-a or tik-b it works.

I'm trying to figure out how to build a template that will work on any tik that supports the UPS values without having to be specific on the last level.

thoughts ??

thank you

some options you could try:

set the oid in the template to for instance: .1.3.6.1.2.1.33.1.4.4.1.{$FINALPART} and on a host level, define the {$FINALPART} macro with the correct value.

or, create a discovery rule that finds the correct oid and build your items with that.

Not really elegant, but if devices behave inconsistent, you'll need to be creative

Hi

Thanks for the ideas. Any pointers on how to create a discovery rule for this ?

Make a discoveryrule on the part of the tree that's always the same. So try for instance on .1.3.6.1.2.1.33.1.4.4.1

if I understand your issue correctly, this would discover:
.1.3.6.1.2.1.33.1.4.4.1.5.6 on tik-a
.1.3.6.1.2.1.33.1.4.4.1.5 on tik-b

and then the item prototype can be .1.3.6.1.2.1.33.1.4.4.1.{#SNMPINDEX}

or something like that. You'll need to play around a bit probably to find the correct setting (or it may not work after all)
