Hi,

At first glance there would appear to be overlap with metrics from the
Linux kernel PMDA - see the nfs.*, nfs3.*, nfs4.* and rpc.* metrics -
are there some additional metrics added here that don't exist there?
Err, look like I missed that the nfs.*.reqs metrics had the different
request types as instances. Pretty much everything that was to be
added with nfsserver pmdas is already covered by the existing linux
kernel pmda.
If yes, we should consider adding 'em into the kernel PMDA alongside
the others; if no, the QA you've added here is still highly valuable
- maybe it could be switched over to using the existing metrics?
Please find below an update to qa/732 which tests the Linux Kernel
PMDA's NFS metrics, I've added the test data from the previously
posted work as a new nfsrpc-root and updated the 732.out to reflect
these changes.

    qa/732 - update with additional stats

    Have added additional stats for the qa/732 run which now run with a
    second nfsrpc-root. Have updated the 732.out to reflect the new
    output

Cheers,

Paul.
