stats

ssh netapp3-asd8.nl.euro.net “stats show -i 5 volume:*:write_data volume:*:read_data”

Stats command has much more possibilities
When you type stats show, it will output you with all the stats there are kept.
This way you can build your own query like for ex.
stats show volume:bullppdata:nfs_protocol_other_latency
This shows the nfs latency of just one volume.

This shows all the values which are in a counter:
ssh netapp4-asd6.nl stats show | awk -F: ‘{print $1}’| sort -u
