From Issue #80December 2000
Not only is this an excellent review, but its also short, but covers alot of the basic material. Besides from being a review and a tutorial, its a inspiration.
I just bought a APC 1000 and had problems with upsd .. but this made me switch over and are now running apcupsd and made tons of scripts to monitor it .. even mrtg. Wonderfull program :)
I will add that we are also successfully monitoring Belkin UPSs with apcupsd.
