NANOG, How can I best monitor power quality (ie: voltage, etc) as a colo customer? We monitor temperature and humidity in multiple places on each floor we are on, network bandwidth/errors/latency/pps/link-state on every link, power used per circuit, tons of metrics on servers, but I can't seem to find a simple and small way to monitor voltage, etc. I looked in the routers, cabinet-level switched power-strips (CDUs), switches, and servers, and I don't see anything we already have that can report that info. I see there are probably some small UPSes ($400 or so) that can report this info. Seems silly to buy UPSes to get that info. Is there a quick/small/handy/better way to get power quality info? If so, what is it? I don't own the facility. Thanks! Mike -- ************************************************************ Michael J.
