rapl-formula 0.5.3

PowerAPI formula using RAPL counters to provides power consumption information.

RAPL-formula

A powerAPI formula using RAPL counters to provides power consumption information of each socket of the monitored machine.

Use RAPL data collected with the hwpc-sensor and convert it into power consumption measures (in Watt). The power consumption measures are store in a MongoDB database.

Quick start

We detail here how to quickly start rapl-formula and connect it to a hwpc-sensor using a mongoDB instance.

For more detail see our documentation here

Get input data

You have to launch the hwpc-sensor to monitor sockets. The sensor must store its data in a mongoDB database. This database must be accessible by the rapl_formula.

Configuration

You can pass the configuration through a file or the CLI. In both case the parameters to precises are the following :

• verbose (bool)
• stream (bool): If working with a sensor in real-time
• input
• output
• enable-cpu-formula (bool): Enable CPU formula', default=True
• enable-dram-formula (bool): Enable DRAM formula, default=True
• 'cpu-rapl-ref-event (str): RAPL event used as reference for the CPU power models, default='RAPL_ENERGY_PKG'
• 'dram-rapl-ref-event (str): RAPL event used as reference for the DRAM power models, default='RAPL_ENERGY_DRAM'
• 'sensor-report-sampling-interval (int): (for stream mode) The frequency with which measurements are made (in milliseconds)
