Getting SNMP data with Telegraf

[laucien]

I know this is gonna sound really noob but for the life of me I can't figure some of this stuff out >.>.

I have a NAS/homeServer with a bunch of VMs and containers. Among those, I have a telegraf docker container that collects a lot of metrics for that server and sends it to the usual influxdb/grafana combo. I want to set that Telegraf instance to also query all the info I can from my router running merlin.

I have no idea how to do it.

I have SNMP correctly set up on the router and using a Linux instance I can query all the info using snmpwalk + public get + IP but I can't figure out which OID addresses mean what or how to group everything in a coherent way to send it into influxdb. I've read several guides that mentioned what each address meant and I could query some but when I tried to query info using tables instead of the ids-thingies I always get an error saying that resource doesn't exist.

I'm obviously screwing up somewhere.

I know it's cheating but... does anyone have some default configs or already-setup stuff I could steal? .

It's pretty standard MIB II stuff. I use a different tool to pull SNMP data, and they had a template for "router" that got most things. For other bits, I just used SNMPwalk from the Linux command line and looked for the info I wanted. I use good, old MRTG. https://oss.oetiker.ch/mrtg/
