@tavyc This is an interesting idea, but I'm not sure how practical it is. For example, on one machine I have, `/dev/disk/by-label/` only maps one device. So it might only...

I think we've talked about this in the past. I'm very much in favor of using `/sys` parsing over `/proc/mdstat`. The only problem is has been lack of time to...

It would be so much easier if the kernel just had a proper metrics interface. :frowning_face:

Interesting, thanks for the report. Very few changes have been made. Only the addition of a couple new metrics. It would be useful to gather some CPU profiles with pprof...

Interesting, I don't see a qdisc call at all in the 0.18 version. But the 1.0.1 is spending a huge amount of time in netlink syscalls. Can you describe your...

Great idea, I did a quick check but it looks like `semctl()` isn't implemented by Go syscal_linux(etc).

The easiest thing to do is get a pprof memory profile. See https://github.com/prometheus/node_exporter/issues/859 for some more tips. It would be useful to look at the the node_exporter's metric, `go_goroutines` over...

Yes, that looks like a goroutine leak. Can you post any pod logs to see if there are any errors?

Thanks, hopefully the pprof dump will give us the information we need.

That is a profile for Prometheus, not the node exporter. You need to use port 9100.
