There are a couple ways that you can monitor the performance for a LUN. Please see Knowledgebase article emc218359 on PowerLink under the Support/Search Support section - this is the main article about using Navisphere Analyzer. You can also use Help in Navisphere - see the section called "Analyzing storage-system performance using Analyzer"  glen
I am looking for documentation with information about the  LUN Properties > Statistics screen on our CX4-240. We just migrated our file server from using RDM's (Physical mode) to vmdk's and I want to monitor utilization and read/write and the statistics screen looks to be a good place for that.  Also curious if there is a better place to monitor performance/utilization/etc. besides this screen.  Eventhough I don't have a baseline of what we were seeing before the migration I still want to watch these statistics for the next week or two and get a better handle on performance/utilization monitoring.  Any idea where I might find this documentation?  Thanks!
