We are experiencing high NFS ops, I am trying to find out who the high offenders are, however I am not sure if there is a better or more conclusive way. Basically: I am doing the following
nfs.per_client_stats.enable on
nfsstat -z
nfsstat -h
nfs.per_client_stats.enable off
At the end of the mail I have attached a copy of the results of the nfsstat -h command (for 1 system). I just look for which systems have the highest percentage of reads and writes. My question is how do determine who the main users are based on the results of this command? Also is there a better way to do this? Are there other commands?
