Description of problem: On a RHEL 9 server with nfsd running and exported shares node-exporter does not export metrics for nfsd (/proc/net/rpc/nfsd). In the node-exporter logs this error is shown: prometheus-node-exporter[2997840]: ts=2024-08-23T08:38:36.096Z caller=collector.go:169 level=error msg="collector failed" name=nfsd duration_seconds=0.00077765 err="failed to retrieve nfsd stats: unknown NFSd metric line \"wdeleg_getattr\"" This issue seems to already be fixed upstream with release 1.8.0: https://github.com/prometheus/node_exporter/pull/2810 Version-Release number of selected component (if applicable): golang-github-prometheus-node-exporter-1.3.1-5.el9.x86_64 How reproducible: Configure an nfs export on RHEL 9 and install node-exporter The nfsd collector is enabled by default in node-exporter Actual results: No nfsd metrics are exported Expected results: nfsd collector works and the metrics are exported
That fix is available for Fedora in the `node-exporter` package. The package `golang-github-prometheus-node-exporter` has been deprecated and `node-exporter` will be the new package. **BUT** the current only available package for EPEL9 is the old `golang-github-prometheus-node-exporter` that was a vendored build. A new solution is on the works[1] that will help to update the package for EPEL and automaticaly `golang-github-prometheus-node-exporter` will be replaced with `node-exporter`. Updating the package manually without the new method is something I want to avoid. [1] https://gitlab.com/fedora/sigs/go/go-vendor-tools/-/issues/10
