Hi List. I am about to buy UPS, but would really appreciate your opinions to make sure I throw money away in the right direction.
1. Can I just assume that device will work reliably if it is listed as supported in nut, upsd or apc-upsd? What should I avoid buying? (All machines involved are running -stable) 2. Are there any problems with the ones that use serial port for accessing status information? What might be the problems with the USB ones? 3. Is the status information reliability/responsiveness decreasing over time as device is getting old or the device just dies at once? 4. What are the ways the UPS device notifies about the fact that it is becoming too old to use and that I should get a new one? 5. Are there ways to monitor the UPS from two (or more) machines? (self-made, three-head serial cable, right ;) ? 6. Which monitoring daemon should I prefer? I do not want my network to get down due to unreliable UPSes, hence all the questions. Google does not include production line experiences, that is why I am asking you. Would be grateful for any input. Thank you for your time. vladas
