Below is an SNMP document for Clariion. I do not believe doing performance polling via SNMP is possible. SNMP on the Clariion side is only used for notifying of problems (or whatever the template is set up to dial home for).

To graph performance, use Navisphere Analyzer (license needed).

You might also want to review EMC Control Center (ECC) - it has an optional module called something like Workload Analyzer (WLA) that will monitor the arrays performance.

I've also heard about something called SMI-S that will allow you to collect performance data from the clariion.

I am leaving snmp behind because i acnnot find anything.
With a mix of Cacti graphing tool and navicli i may could graph some data though.

Do you know a way to retrieve the Utilization% value from navicli for a whole LUN?
I am able to see per-disk Busy% with a simple command like this:

navicli -h 10.130.12.200 getlun 101 | grep Busy
Prct Busy: 36.48
Prct Busy: 36.19
Prct Busy: 36.41

If you have Analyzer enabled on the array you can export performance data to csv files. The files will contain the data set in columns that can easily be graphed in a spreadsheet.

If you are interested in SaaS (web) based tool to help you do this, check out http://www.interscapetech.com. You can upload WLA (ttp files) or nar data files to have them charted nicely for you. The tool is called perfonics and can provide you a nice PDF file or online dashboards that shows the various very helpful performance views.
