Hello we are running Ontap 9.2
We are monitoring hardware performance and regularly during the day especially in afternoon hours we see spikes in CPU usage up to 90%
Is there a way to discover what the cause is?
We were running some commands
priv set diag;statit -b
priv set diag;statit –e
sysstat -x
Attached are some results and comparison of 2 different results.
The spikes are for few seconds and goes down to 20%.
Thank you,
Martin
