The goal isn't to monitor the UPS, it's to monitor the power supplies on the individual servers. Just monitoring the UPS isn't sufficient if you have a power supply failure. > How do you expect software on a computer to tell you when the power > supply on that computer has gone to zero volts? Because it should know the voltage coming of each power rail? These servers have dual power supplies, and I'm looking to detect a failure with *one*. Detecting a failure in both is easy - the box is offline. Jacob
