Static Metric Labels?

[AaronWiggins27]

Collecting SNMP data for sensors and I'm looking to put static labels for metrics. For example, the oid below is a digital sensor and I want to add a second label named sensor_type with the label "digital". This is just one way that I've tried but it did not work. Is there a way to do this? There are different sensors like digital, internal, analog, etc... so I would not add it to the scrape_configuration.

• name: room_alert_digital_sen1_1
  oid: 1.3.6.1.4.1.20916.1.11.1.2.1.1
  type: gauge
  indexes:
  • labelname: label
    type: gauge
    lookups:
  • labels:
    • label
      labelname: label
      oid: 1.3.6.1.4.1.20916.1.11.1.4.2.1
      type: DisplayString
  • labels:
    • label
      labelname: sensor_type
      value: "digital"
      type: DisplayString
