(Please download the latest version of the perfstat every time before you run it)
The tool should be run from a host with RSH or SSH access to the NetApp system and preferably a host where the problem has manifested. The statistics should also be collected during the time of the performance degradation.
INSTRUCTIONS FOR SETTING UP RSH ACCESS FOR THE HOST:
Once RSH is working, you can run the Perstat utility, and upload the resulting output:
Please collect a PERFSTAT with the following command while the performance impact is being experienced:
perfstat -f [filer] -l root:[passwd] -t 20 -i 6 –I > .perfstat.out (this will collect via RSH)
perfstat -f [filer] -l root -S pw:[passwd] -t 20 –i 6 –I > perfstat.out (this will collect via SSH)
This will run 6 iterations at 20 minutes covering about 2 hrs.

** Windows hosts should have the tool PLINK in the same directory as perfstat.exe to run SSH.
** Linux/Unix hosts are not able to run SSH via password authentication, they must use key files.
***If you run into problems running the SSH command, please refer to the following link:
***When using Perfstat with Windows 7/2008, you much use Open SSH. For instructions on how to do that, please refer to this link: ht tps://kb.netapp.com/support/index?page=content&id=1013882
