I was wondering if there is documentation that details the meanings of
everything in /proc/net/rpc/nfsd

I know what th is, but I am curious what other information I can glean
from the file.

Thanks for your help,

NFSv4 is a bit more difficult as there are only 2 RPC calls that are
defined: NULL and COMPOUND.

We're working around this to provide more detailed statistics, but for
the moment we're limited to the following:

  <NULL> <COMPOUND> <READ> <WRITE> <COMMIT> <OPEN> <OPEN_CONFIRM>
  <CLOSE> <SETATTR>

(where <COMPOUND> in the above list means: "all other operations")

Cheers,
  Trond

Hi Trond,

Have the newer statistics counters been put in since 2.5.66?  On 2.5.66 all
I see are 'proc4 <nproc> <#null> <#compound>'.  It's good to know more
detail is being added; I really need to grab the latest bits.

Grab the latest bk snapshot. The NFS client on 2.5.x wasn't really
very stable prior to Tuesday's snapshot.

But yes: as you can see we are in the process of adding stuff to the

more detailed statistics (and hopefully also faster+better NFSv4
performance).
