In regards to monitoring the per-second performance with mysqladmin, I have recently written a tool to make this much easier. I call it "innotop" and you may download it from my website, http://www.xaprb.com/blog/2006/07/02/innotop-mysql-innodb-monitor/ If you have any comments please let me know, I'd like to make it as useful as possible.

This is not to count all other caches you might have. I did not mentioned it to avoid complicating things. If you have caches on the front you would normally have lower cache hit ratio on the system Sure. This is not to count all other caches you might have.

Since the io stats is io down to disk so you dont forget already cached queries either with mysql query cache or if you use a 3rd party solution such as memcached or similar.
