We have some outlets in our office that we think may be getting current or voltage surges in the early AM hours. One symptom I see is a UPS attached to the circuit is reporting constant on and off events. What is the cheapest way for me to get some direct measurement of this, starting at the wall plug? I'm hoping someone makes a cheap data logger that would track voltage and current, so we could see any distinct spiking or surging activity in a timeline graph.
