How do you check which nfs client uses most of your filer’s nfs operations? . You have to enable the option “nfs.per_client_stats.enable”. This option would give you per nfs operations stats per client.
Enable nfs per client stats.
[root@foo23 ~]# ssh filer1 options nfs.per_client_stats.enable on
Use “nfsstat -l” to display client statistics.
[root@foo23 ~]# ssh filer1 nfsstat -l
