Description Barry Scott 2023-12-11 16:02:54 UTC

This log is happening every time node exported polls, every minute in my case.

prometheus-node-exporter[13178]: ts=2023-12-11T15:58:45.648Z caller=collector.go:169 level=error msg="collector failed" name=nfsd duration_seconds=4.5445e-05 err="failed to retrieve nfsd stats: unknown NFSd metric line \"wdeleg_getattr\""



Reproducible: Always

Steps to Reproduce:
1.configure and run node exporter
2.
3.
Actual Results:  
prometheus-node-exporter[13178]: ts=2023-12-11T15:58:45.648Z caller=collector.go:169 level=error msg="collector failed" name=nfsd duration_seconds=4.5445e-05 err="failed to retrieve nfsd stats: unknown NFSd metric line \"wdeleg_getattr\""



Expected Results:  
no log generated


Update to either not log for this missing field or not try to get this field at all.

Comment 1 Mikel Olasagasti Uranga 2023-12-11 17:13:53 UTC

Fixed in rawhide with golang-github-prometheus-procfs-0.12 and newer node-exporter built with that procfs package.

Issue introduced with kernel 6.6 and reported upstream https://github.com/prometheus/node_exporter/issues/2799 

Fix: https://github.com/prometheus/procfs/pull/574

I can try to backport newer procfs & node-exporter to F39. Part is already done in https://bodhi.fedoraproject.org/updates/FEDORA-2023-833c31bec9 but can take some days.

Many thanks.

I can test as soon as there are packages available and give Karma.
