Telegraf

After a standard upgrade, telegraf is now constantly crashing with the following:

I haven’t made any changes to the config and the config for ethtool looks like this:

[[inputs.ethtool]]
  interface_include = ["enp0s25","wlp3s0"]

Which has been working for a long time. Both of those are valid interface names and even if I comment out the include line, it still keeps crashing.

I’ve now had to stop the monitoring of the network.

Can someone please help?

Thanks J.

Can you check the artifacts in this PR and let me know if this crash stops?

Thanks!

Hi, sorry I don’t know how to do that.

There is a comment from the Telegraf Tiger on that PR. It has links to telegraf archives, that you can extract, and then run. It would help us to know if this existing PR fixes this issue as we had another user mention this same thing.

OK, thanks. I’m out of time for now. Will try to get to it as soon as I can.
