[Observium] Timeticks in Custom OID

Hello,

i would like to monitor dot1dStpTimeSinceTopologyChange (numeric oid 1.3.6.1.2.1.17.2.3.0) which is a Timetick.

I have tried it as Gauce and also as Counter but always gives Draw Errors and not values.

Do you have any idea how to do this?

Kind regards

Philipp
