It is a common request from customer that wants to know who are the most active clients to a system. Though not hard to obtain, there is no obvious menu that lets you do that, so there it is :
First of all, you need to be in advanced mode and start statistics collection for the “client” object :
netapptest2::*> set advanced
Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.
Do you want to continue? {y|n}: y
netapptest2::*> statistics start -object client
Then you let it run for some time, and you can start looking at who the most active clients are : netapptest2::*> statistics show -object client -instance !Cluster* -sort-key nfs3_ops -counter nfs3_ops -tab ntap2_vs1: client: 5/31/2016 23:59:26 instance nfs3 name ops ---------------------- ---- ntap2_vs1:10.20.245.11 31 ntap2_vs1:10.20.45.95 0 ntap2_vs1:10.20.45.67 0 ntap2_vs1:10.20.45.60 0 ntap2_vs1:10.20.45.58 0 ntap2_vs1:10.20.45.43 0 ntap2_vs1:10.20.45.40 0 ntap2_vs1:10.20.45.39 0 ntap2_vs1:10.20.45.37 0 ntap2_vs1:10.20.45.33 0 ntap2_vs1:10.20.45.235 0 ntap2_vs1:10.20.45.234 0 ntap2_vs1:10.20.45.226 0 ntap2_vs1:10.20.45.225 0 ntap2_vs1:10.20.45.223 0 ntap2_vs1:10.20.45.221 0 ntap2_vs1:10.20.45.218 0 ntap2_vs1:10.20.45.195 0 ntap2_vs1:10.20.45.19 0 ntap2_vs1:10.20.45.183 0 ntap2_vs1:10.20.45.18 0 ntap2_vs1:10.20.45.158 0 ntap2_vs1:10.20.45.157 0 ntap2_vs1:10.20.45.156 0 ntap2_vs1:10.20.45.134 0 ntap2_vs1:10.20.45.133 0 ntap2_vs1:10.20.45.132 0 ntap2_vs1:10.20.45.124 0 ntap2_vs1:10.20.45.120 0 ntap2_vs1:10.20.45.118 0 ntap2_vs1:10.20.45.114 0 ntap2_vs1:10.20.45.113 0 ntap2_vs1:10.20.45.108 0 ntap2_vs1:10.20.45.100 0 34 entries were displayed.
You can use another field instead of nfs3_ops, just use “?” character to get a list of available fields when you get to that part of the command line.
Here are the options available at this time, you can also use multiple fields by using a comma “,” separator.
cifs_ops cifs_read_ops cifs_read_size cifs_write_ops cifs_write_size instance_name instance_uuid local_ops mount_ops nfs2_ops nfs3_ops nfs4_ops node_name node_uuid process_name remote_ops rx_data rx_packets total_ops tx_data tx_packets vserver_id vserver_name
statistics start -object client run first time and I was able to get the statistics show.
next time onwards its giving below errors
statistics start -object client

It happens, but usually on the first collection from my experience.
Were you able to re run it?
Very useful!
How does that correspond with the “Top Clients” on the System Manager Dashboard?
It should give you similar results, but using System Manager is much easier today 🙂
