Snip from my application:
-----
Collecting data on the server side was discussed on phpmyadmins
mailing list several times and a consensus could not yet be found. The
major objections raised were that additional steps would have to be
taken by the user to set up a periodical collection of data, and that
competition with established monitoring tools like cacti was not
desired. To stay flexible regarding this issue, the protocols used in
my implementation will also allow for data possibly recorded in the
past to be transferred, although server side data collection will not
be part of my project.
-----

I'll try to get something with scheduled events started as a parallel project.
