How can I check VNXe processor performance?
Within Unisphere, go to System > Processor Performance.
The CPU Usage History chart displays I/O performance statistics for Storage Processors (SPs) in your system. The statistics are color-coded for each SP. Beneath the graph, click the check box next to each SP to hide or show the line graph for a particular SP. Mouse-over a line graph to view the usage percentage and date when the performance statistics were collected.
Chart Components and their Descriptions
Percentage: Percentage of SP utilization up to 100%
Duration: Date and time over the specified interval.
Timeframe: Click to select a time period: hourly, last 24 hours, or last 48 hours.

Hi - you can also accomplish this via the CLI as follows:
CPU utilization graphs need to be generated for each service processor.
A. Establish ssh to VNXe - you will access either spa or spb
B. cd to cd /var/log/sa
Example:
service@(none) spb:/var/log/sa> ls -l
total 27716

C. less sarXX where XX is two digit number correlating to day of the month
Example:
This shows values for spb:
service@(none) spb:/var/log/sa> less sar01

D. Issue "ssh peer" to access other Service Processor
Example:
service@(none) spb:/var/log/sa> ssh peer
Last login: Wed Oct 1 20:05:25 2014 from peer
service@(none) spa:~> cd /var/log/sa
service@(none) spa:/var/log/sa> ls -l

E. Repeat above steps to gather CPU metrics for service processor A.
NOTE:
Time interval is very 10 minutes for each CPU CORE 0,1,2 and 3.
NOTE:
Deduct %idle from 100 to derive CPU utilization
