interesting point: I'm thinking of some logging improvements, such as:
- making upslog a real daemon, able to log data from several UPSs,
- making log asynchronous and smart (ie log only things that have changed),
- switching by default to a NUT specific logfile (ie upsd.log), instead of
the syslog default,
- adding the ability to log to other system, such as RRD...

So, I'm definitly interested in your work.

The final aim of all of that is to be able to use these data for plotting
and other graphic / textual display... I've planned to get back on this when
working on some MGE PSP [1] evolution such as the History feature in our
