snmp_exporter: lookups doesn't work as expected with PowerNet MIB

[Egor Vasilyev]

I use APC PowerNet MIB 4.2.6. My generator.yaml:

modules:
  template_acrd_602:
    version: 3
    max_repetitions: 25
    retries: 3
    timeout: 30s
    walk:
      - coolingUnitStatusAnalogTableIndex
      - coolingUnitStatusAnalogDescription
      - coolingUnitStatusAnalogValue

I try:

# curl -sw '' 'http://127.0.0.1:9116/snmp?module=template_acrd_602&target=hostname'

And receive (the original output contains dozens of metrics, I shrank it):

coolingUnitStatusAnalogDescription{coolingUnitStatusAnalogDescription="Air Filter Run Hrs",coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 1
coolingUnitStatusAnalogTableIndex{coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 44
coolingUnitStatusAnalogValue{coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 4472

And it's ok. But if I add a lookup section into generator.yaml like this:

modules:
  template_acrd_602:
    version: 3
    max_repetitions: 25
    retries: 3
    timeout: 30s
    walk:
      - coolingUnitStatusAnalogTableIndex
      - coolingUnitStatusAnalogDescription
      - coolingUnitStatusAnalogValue
    lookups:
      - source_indexes: [coolingUnitStatusAnalogTableIndex]
        lookup: coolingUnitStatusAnalogDescription

I expect to receive an output something like this:

coolingUnitStatusAnalogDescription{coolingUnitStatusAnalogDescription="Air Filter Run Hrs",coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 1
coolingUnitStatusAnalogTableIndex{coolingUnitStatusAnalogDescription="Air Filter Run Hrs"coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 44
coolingUnitStatusAnalogValue{coolingUnitStatusAnalogDescription="Air Filter Run Hrs"coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 4472

But actually I receive:

coolingUnitStatusAnalogDescription{coolingUnitStatusAnalogDescription="",coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 1
coolingUnitStatusAnalogTableIndex{coolingUnitStatusAnalogDescription="",coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 44
coolingUnitStatusAnalogValue{coolingUnitStatusAnalogDescription="",coolingUnitStatusAnalogTableIndex="44",coolingUnitTableIndex="1"} 4472

What am I doing wrong? Help please. Thank you!

OID description you could get on web site

The index for these metrics has two index components, so when doing lookups you have to include both.

modules:
  apc_cooling:
    walk:
    - coolingUnitStatusAnalogTable
    lookups:
    - source_indexes:
      - coolingUnitTableIndex
      - coolingUnitStatusAnalogTableIndex
      lookup: coolingUnitStatusAnalogDescription
