How to add syslocation for PDUs - snmp_exporter

[wade-lich]

I want to be able to poll prometheus for the overall apparent wattage of ServerTech PDUs and other metrics that are gathered as well. Once I get one use case working it should be a cake-walk to propagate to others.

Currently, the default generated out put for polling the servertech is :

TYPE st4InputCordApparentPower gauge

st4InputCordApparentPower{st4InputCordName="PDU-ATL1-S12C-0104-L1B",st4UnitName="PDU-ATL-S12C-0104-L1B"} 6651
st4InputCordApparentPower{st4InputCordName="PDU-ATL1-S12C-0104-R1R",st4UnitName="PDU-ATL-S12C-0104-R1R"} 3585

I want to also inclide the syslocation so that I can group by rack:

TYPE st4InputCordApparentPower gauge

st4InputCordApparentPower{sysLocation="ATL-S12C-0104", st4InputCordName="PDU-ATL1-S12C-0104-L1B",st4UnitName="PDU-ATL-S12C-0104-L1B"} 6651
st4InputCordApparentPower{sysLocation="ATL-S12C-0104", st4InputCordName="PDU-ATL1-S12C-0104-R1R",st4UnitName="PDU-ATL-S12C-0104-R1R"} 3585

I can get the sysLocation to show up as a metric, but I cannot figure out how to add it the above.

I added to the snmp.yml:

get:
- 1.3.6.1.2.1.1.6.0
metrics:
- name: sysLocation
  oid: 1.3.6.1.2.1.1.6
  type: DisplayString
  help: A textual description of the entity - 1.3.6.1.2.1.1.6

So far so good.

But no matter what I've tried I cannot get that into the output of:

  - name: st4InputCordApparentPower
  oid: 1.3.6.1.4.1.1718.4.1.3.3.1.5
  type: gauge
  help: The measured apparent power of the input cord in Volt-Amps. - 1.3.6.1.4.1.1718.4.1.3.3.1.5
  indexes:
  - labelname: st4UnitIndex
    type: gauge
  - labelname: st4InputCordIndex
    type: gauge
  lookups:
  - labels:
    - st4UnitIndex
    labelname: st4UnitName
    oid: 1.3.6.1.4.1.1718.4.1.2.2.1.3
    type: DisplayString
  - labels:
    - st4UnitIndex
    - st4InputCordIndex
    labelname: st4InputCordName
    oid: 1.3.6.1.4.1.1718.4.1.3.2.1.3
    type: DisplayString
  - labels: []
    labelname: st4UnitIndex
  - labels: []
    labelname: st4InputCordIndex

Any assistance would be appreciated.
