Sensors

Here you can find every kind of sensors collecting raw data useable by PowerAPI to compute energetic estimation.

Code in this page is not tested :D

HWPC-Sensor

The HWPC-Sensor (Hardware Performance Counters Sensor) get data from hardware performance counters reachable in recent processor. You have to provide him a MongoDB database for saving data. Docker image can be downloaded with the following command:

docker pull gfieni/hwpc-sensor

When the image is correctly downloaded, you can run the sensor with the next following command:

docker run --privileged --name powerapi-sensor -td \
           -v /sys:/sys \
           -v /var/lib/docker/containers:/var/lib/docker/containers:ro \
           -v /tmp/powerapi-sensor-reporting:/reporting \
           HWPC_DOCKER_IMAGE -n "SENSOR_NAME" -r "mongodb" -U "mongodb://MONGO_ADDRESS" -D "DATABASE_NAME" -C "COLLECTION_NAME" \
           -c "sys" -e "INSTRUCTIONS_RETIRED" \
           -c "cycles" -e "CYCLES" \
           -c "llc" -e "LLC_MISSES" \
           -c "rapl" -e "RAPL_ENERGY_CORES" -e "RAPL_ENERGY_PKG" -e "RAPL_ENERGY_GPU" -e "RAPL_ENERGY_DRAM"

These parameters had to be configure:

• HWPC_DOCKER_IMAGE:HWPC-Sensor docker image name.
• SENSOR_NAME: Sensor name.
• MONGO_ADDRESS: MongoDB server address.
• DATABASE_NAME: MongoDB database name.
• COLLECTION_NAME: MongoDB collection name.
