Are there any tools, or options (from VSphere client) that I can try to find the memory and disk performance of an ESXi5 host and the VMs hosted on it ?

Did you not ready the documentation at all? – Chopper3 Sep 8 '12 at 15:20

Yes, you can use the performance monitoring graphs provided by the vSphere client.

At the host level and the individual VM level, there's a "Performance" tab that provides some insight into the Disk, Memory, CPU, Network and other system metrics as real-time graphs. Using vCenter centralized management will add historical metrics as well.

I knew about this option and exported it to a spreadsheet. My concern here is the disk performance. The sheet on disk performance gives data, I am not sure if these are disk queue length (the values are not labeled I think and am not sure if these values and thresholds to compare performance with would be same as those in a windows server 2003/2008). Apologies, I should have been more clear in my first query. – whizkid Sep 8 '12 at 18:39
I got the thresholds from the vSphere documentation. Thanks! – whizkid Sep 8 '12 at 18:59
