Do you have easy ways to monitor power usage on any power plug over time, without needing to check out a display on the plug or to install some shady chinese Android app?
I have a nice used Dell Poweredge T320 with a single Xeon E5-2428L that's been running on only an SSD (and then a raid 1 of 3.5" HDDs) for over 8 years, but electricity prices are rising and I wish I could measure it precisely, idle and under load.
While no broken out per plug, APC UPS network management cards provide total power output data (current, voltage, frequency, power) via SNMP, which you can log using a wide variety of tools.
And even without external tools, historical power usage logs are available via the APC Web UI.
While I don't currently log anything externally, I use an xbar[1] script[2] to display UPS output current in my Mac menu bar.
