Note that this will only work if you are using rrdtool as the backend. 
rateup only understands integers.  With rateup you would probably need
to play with the scale command.

I recently set up a host-template for to make monitoring our multitude
ups easier.  I monitor upsEstimatedMinutesRemaining,
upsSecondsOnBattery, upsInputVoltage, upsOutputVoltage, and
upsBatteryVoltage.  I've also got it integrated into Big Brother so that
it will alarm me at appropriate times.  If you want a copy, I've posted
it at http://www.austinnetworkdesign.com/mrtg/ups.template
The template can be called using the --host-template directive on
cfgmaker, so:
/usr/local/mrtg-2/bin/cfgmaker --nointerfaces
--host-template=ups.template --output=foo-ups.cfg
public at foo-ups.ip.address

It also assumes that you have added the ups mib to your loadmibs line.
