Exported data ifPhysAddress from agents

[chrisho95]

Hi,

I'm trying to pool the information of the mac addresses of the different devices from Horus.

The polling goes well but the agents do not expose the results.

Looks like Horus doesn't recognize the "PhysAddress" data type.

"ID": 39,
 "Name": "ifPhysAddress",
 "Oid": ".1.3.6.1.2.1.2.2.1.6",
 "Description": "The interface address at the protocol layer immediately below the network layer in the protocol stack.",
 "PollingFrequency": 0,
 "LastPolledAt": null,
 "Active": true,
 "ExportAsLabel": false,
 "ExportedName": "if_phys_address",
 "PostProcessors": []
}

Reponse:

{"oid":".1.3.6.1.2.1.2.2.1.6","name":"ifPhysAddress","exported_name":"if_phys_address","description":"The interface address at the protocol layer immediately below the network layer in the protocol stack.","value":"\u0000\ufffd\ufffdﻫ","index":"36044800"}

The type of value "ifPhysAddress" is PHYSADDRESS.

BR,

Christophe.

Hi,
The PhysAddress type is not implemented by the underlying gosnmp library.

You can create a feature request there to add this type (their readme has instructions on how to do that).

Another possibility would be to add a specific post-processor for this metric to convert the output to a mac address. I'll see what I can do as unfortunately I don't have access to a test environment anymore. It would help me a lot if you can send me by PM the output of horus-query for this specific query at debug level -d3 with the corresponding tcpdump.
