A simple script to measure power consumption of an IPMI enabled system (using ipmi-sensors) while executing a given application. The script can perform two operations: log the power consumption and read an existing log file and report the average watts consumed. The consumption sample is taken by default every 1 second. That can be easily altered either within the script or by introducing an additional user argument.
For logging consumption:
$ ./watt_log.sh get <logfile> <application in ps>
Once the logging will start, the script will automatically stop when the application will finish executing. For interrupting this, CTRL+C would work as well without affecting the logged entries.
For reporting average:
$ ./watt_log.sh average <logfile>
