System info

Telegraf 1.33.0, RHEL 9.5

Docker

No response

Steps to reproduce

  1. Install AOS 8.10 mibs in snmp mibs path
  2. Start tcpdump looking for port 161 traffic
  3. Run minimal.telegraf.conf against a Aruba 9240 WIreless controller

Expected behavior

Metrics are collected by telegraf and network traffic is observed in tcpdump

Actual behavior

No metrics are collected and no network traffic is observed

Additional info

This was working when I was using the net-snmp translator, but I've since moved over to gosmi.

Theres no logging telegraf side that indicates it's unhappy with anything I've set so not sure why its not even attempting to reach out

Andrene avatar Jan 31 '25 19:01 Andrene

@Andrene are you sure you can reach the SNMP endpoint from your Docker container at all? Could you try with e.g. the SNMP tools?

srebhan avatar Mar 04 '25 16:03 srebhan

Hello,

Not using docker at all, just RHEL physical and virtual hosts. I am able to reach the endpoint using normal net-snmp commands, and if I comment out the gosmi translator so that it uses the netsnmp translator it does grab data

If I specify the non-numeric oid it does yell at me that it can't translate it, so I'm guessing gosmi is having issues reading the mibs from the path specfied?

Probably related to https://github.com/influxdata/telegraf/issues/10793

Can you try be specifying the table fields manually?

Hipska avatar Mar 06 '25 13:03 Hipska

You would be correct, I am hitting that issue.

Specifying the fields makes it work as expected.

Thanks!
