nfsd collector is default, while documentation states that it isn't a default collector.

node_exporter command line flags

Are you running node_exporter in Docker?

No.

What did you do that produced an error?

After compiling per documentation, getting regular console errors for nfsd collector

What did you expect to see?

No issues, as I am not using nfs nor expected the collector to be enabled by default

What did you see instead?

ERRO[0233] ERROR: nfsd collector failed after 0.000149s: failed to retrieve nfsd stats: open /proc/net/rpc/nfsd: no such file or directory source="collector.go:136"

This was a bug, it's now fixed in the latest master. I will update the README to point out that this is a default collector now.

I recommend building from a release tag to avoid getting random bugs from master. 😄

Thanks -- that's what I did once I realized I forgot that step, after submitting the report, but then again, Documentation is generally hard. As a consumer of a given product, I appreciate the quick update! I would have contributed the update, had I known if this was the behavior intended or not.
