I believe that their are rrd tools for many platforms available. But
this would add new requirements to the environment in which pma is
installed. It would also burden the administrator with extra complexity,
as a writable filesystem location and the privilege to execute external
binaries would be required.

One of the sweet things of pma is in my opinion that it works for the
most part out-of-the-box. We should be very careful not to lure people
with nice features, which these statistics would be, and then jump
through a complex installation.

I'm very curious if the mysql 5.1 event scheduler combined with pmadb
storage would be reliable and easy maintainable.
