SNMP: add alias tag

[r0bj]

There is "ifName" OID (1.3.6.1.2.1.31.1.1.1.1) but also "ifAlias" (1.3.6.1.2.1.31.1.1.1.18) as a custom port description. It would be great to have ability add additional tag as alias.

Maybe as an additional mapping_table in config?

ifName:

snmpwalk -v2c -c public 127.0.0.1 1.3.6.1.2.1.31.1.1.1.1.8
iso.3.6.1.2.1.31.1.1.1.1.8 = STRING: "eth2"

ifAlias:

snmpwalk -v2c -c public 127.0.0.1 1.3.6.1.2.1.31.1.1.1.18.8
iso.3.6.1.2.1.31.1.1.1.18.8 = STRING: "GTS"

Example of line protocol:

ifHCInOctets,host=gw1,instance=eth0,alias=GTS,unit=octets ifHCInOctets=378553758147i 1458676458140933859

This is a good idea ! In fact, we have to add the string data support in snmp plugin... Also, All string data could be processed as influxdb tag or as influxdb field.

@sparrc Is there any issue to send string data as value in influxdb from Telegraf

[titilambert]

To get this working we need to get the issue #808 done first ( be able to merge data in the same measurement )

[sparrc]

Nope, strings are allowed in the database as both fields and tags

Hey, I wonder if there has been any movement on this?

This would be really handy to have. Not sue where I would need to start if I were to submit a patch myself, if someone could make any suggestions?

with the new SNMP plugin (#1389) the user can now specify SNMP OIDs to be used as tags, which I believe fixes this issue.

It will be available in release 1.0
