snmp-exporter-aerohive

Build Prometheus Exporter with specific aerohive mibs

purpose

a custom configuration of snmp-exporter allows more data.. in this case.. better monitoring for my aerohive APs.

approach

goal is to build by sourcing upstream repo, add customizations, and then cross compile artifiacts.

we'll decouple the binary artifacts from containers to make builds efficient.

sadly above doesn't make sense as it's just the snmp.yml that needs to be generated :P

mibs

going to use aerohive mibs from https://github.com/netdisco/netdisco-mibs.git since they have some corrections. Fixes probably not needed, but why not.

place mibs in mibs folder

generating snmp.yml

MIBSDIR variable imporant

cd generator
MIBSDIR=mibs make generate

converting hexadecimal to string

most of the string values are returned as hex... we need ot convert them..

apparently overrides in generator.yml is the most friendly way

update

overrides in generator.yml didn't cover all teh touchpoints. i had to manualy change some types in snmp.yl from OctetString to DisplayStirng
