Forwarding Shade's response:

    Thanks for the suggestion. As far as I know they only have a Java client which will probably work in linux but we run headless servers. I've also suggested this or asking for a CLI version from them but the guys at work figured NUT should be able to do the job.

With that being said I also noticed if you're using their SNMPWEBCARD they have bug and report the load wrong and I forgot to mention it. Are UPS was under a 19% load and NUT was reporting 190, when I called their tech support they told me it was a limitation in the software, theirs software or the SNMP protocal I believe, where they're supposed to be sending a float but only send an int. Instead of just dropping the decimal and everything after or rounding logically they just take out the decimal completely and return all the numbers.
