Hi,

just for the benefit(?) of the group, what I do right now is

- run a script that invokes 'monitorlm' in regular time intervals
  and writes the usage info to a separate log file.
  Format:
     2004-05-03T15:20+0000 - FE: 4, KE: 2

- another script will (at request) read this log file and
  compute simple usage statistics.

This approach works fine for me.

For Mathematica 4.x I, had a little program that would read
the mathlm log file directly and extract the info from there,
but I figured out that it needs too much effort to keep up
with Wolfram's changes in the log file format...

Regards,
Marcus
