The event monitors are explained in great detail here:

I'd like to see a similar list for the snapshot monitors, does anyone have a link?

The list above is still useful for snapshot monitors, because the information is basically the same though.

Edit (couldn't be posted yet):

It's here: http://publib.boulder.ibm.com/infoce...c/r0007594.htm

If I want to know how long I'm waiting for I/O, I should calculate

pool_read_time-pool_async_read_time
+pool_write_time-pool_async_write_time
+prefetch_wait_time

, right (note the prefetch wait time, which makes up a substantial amount in the current case)?
