Problem:
How can I check performance of disks CPU Controllers LUNs and Volumes on a NetApp FAS or AFF system?
Solution:
Elevate privileges for the session:
set -privilege diagnostic
This command will show periodic data (use Ctrl-C to stop):
statistics show-periodic -node node1
These commands will show various aspects of the SAN:
statistics lun show statistics volume show statistics disk show statistics system show statistics top client show statistics cache flash-pool show statistics node show
These commands will start collecting statistics and then stop when ready:
statistics start -object system -sample-id smpl_1 statistics stop -sample-id smpl_1 statistics show -sample-id smpl_1
These commands will collect the statit preset. Note that -b is start and -e is stop. You also have to specify the node run to choose a contoller.
node run -node san_node_1
priv set diag
statit -b
statit -e
