[TriLUG] NFS client connections and stats

[Mike Viscount via TriLUG]

Without checking the google ... I believe that nfsiostat is a client side
tool and hence the message you're getting.

Try iostat on the server ... may be an NFS option ... -n maybe ... man
iostat will tell you.

To see who is mounting the filesystems (NFS clients) ... the showmount
command on the nfs server should give you that info.  Again, man is your
friend :-)

Next likely question ... on the NFS server how can I monitor the load being
put on it by the nfs clients ... good question ... Dear Mr. Google, How can
I .... :-)

nfsstat should tell you NFS server stats but not sure if that can be used
to give client request stats for load determination.

Once you know the clients you can do some nfsiostat commands on those to
see who is pounding hardest, issue commands remotely via ssh, but ideally
checking the request load on the server would be better/best.

To busy w/ work right now to dig in and don't know off the top of my head
but hope the above is helpful.
