Description Marko Myllynen 2015-07-13 11:54:47 UTC

Description of problem:
sar -n NFS / sar -n NFSD provide easy access to NFS(D) statistics but while PCP already collects all the related low level metrics, none of the PCP utilities provide them in such a quick manner (IOW, one wanting to monitor NFS with PCP would need to type lots of metrics manually with pmdumptext or to write some sort of a wrapper script).

pmcollectl mentions NFS but the feature is unimplemented. Another alternative might be to provide pcp-nfsiostat based on nfsiostat(1).

Comment 1 Nathan Scott 2015-10-12 01:07:46 UTC

FYI - pcp-atop(1) in pcp-3.10.8 will have support for reporting per-client NFS metrics (pmdanfsclient), as well as the NFS/RPC stats from clients and servers using some of the kernel stats (pmdalinux).

This is not as extensive a pcp-nfsiostat(1) would be, but its a good start.

Comment 2 Fedora End Of Life 2016-07-19 15:20:04 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 3 Marko Myllynen 2016-12-13 12:00:40 UTC

FWIW, this can be now done with pmrep(1), see:

Thanks.
