I was wondering if there was a tool available to monitor the current ramdisk throughput. I found that with sysstat, iostat, etc. I am only able to monitor the current throughtput of physical devices.

What I'm looking for is a tool which generates an output indicating the current throughput. Something like:

DEV         write        read       overall
ramdisk-1   1.4 GB/s     0.4 GB/s   1.8 GB/sec

Do you guys have an suggestions on how to generate this metric?

Did you try the df command? If your volatiles are tmpfs organized, it's great. if they are ramfs oriented... you'll have to estimate the memory size from a free command I guess.

   diag@diag-gnu:~$ df -h
