What did you do that produced an error?

Attempting to manually create a config to pull a measurements with a couple of tags.

What did you see instead?

# TYPE internal_sensor gauge
internal_sensor{name="",type=""} 7766

The tags do not come across, so I feel like I'm doing it wrong, but I'm not able to find a good example of single OID pulls.
Is this not possible, or am I just doing it wrong?

You are specifying an index in your lookup labels. It's trying to find that label index on the metric. Since your metric has no index there's nothing to match.

I haven't tried this, but maybe it would work with no lookup index?

modules:
  roomalert_snmp:
    get:
    - 1.3.6.1.4.1.20916.1.9.1.1.1.2.0 # Metric
    - 1.3.6.1.4.1.20916.1.9.1.1.1.3.0 # Device Name
    - 1.3.6.1.2.1.1.5.0 # Device Type
    metrics:
    - name: internal_sensor
      oid: 1.3.6.1.4.1.20916.1.9.1.1.1.2.0
      type: gauge
      help: The temperature reading in Fahrenheit of the Internal Sensor
      lookups:
      - labels: []
        labelname: name
        oid: 1.3.6.1.4.1.20916.1.9.1.1.1.3.0
        type: DisplayString
      - labels: []
        labelname: type
        oid: 1.3.6.1.2.1.1.5.0
        type: DisplayString

Thanks for the guidance. I just need to figure out the exact syntax to make them tags. I took your example and got no tags, so I tried to specify a tag for one of them (even though it has nothing to replace). Still no dice.

    - 1.3.6.1.4.1.20916.1.9.1.1.1.3.0 # Sensor Name
    - 1.3.6.1.2.1.1.5.0 # Device Name
    metrics:
    - name: internal_sensor
      oid: 1.3.6.1.4.1.20916.1.9.1.1.1.2.0
      type: gauge
      help: The temperature reading in Fahrenheit of the Internal Sensor
      lookups:
      - labels: [type]
        labelname: type
        oid: 1.3.6.1.4.1.20916.1.9.1.1.1.3.0
        type: DisplayString
      - labels: []
        labelname: device_name
        oid: 1.3.6.1.2.1.1.5.0
        type: DisplayString

You can see the top one actually has the label, but no value. The bottom one doesn't even show up.

# HELP internal_sensor The temperature reading in Fahrenheit of the Internal Sensor
# TYPE internal_sensor gauge
internal_sensor{type=""} 7811

Yea, I don't think this is kind of non-indexed supported right now.

well darn
