CPU/RAM & power consumption extraction for a given processing task

This repository contains scripts and tools for extracting CPU/RAM and power consumption while a processing task is being carried. The selected processing task is a video streaming transmission (making use of ffmpeg open source tool), although any other app could be executed, and the CPU/RAM & power consumption extraction should work without being affected. For the power consumption extraction in specific, a smart plug (Shelly Plug S) is being used. Such device sends the consumption periodically via MQTT, which could be extracted using the monitor_power_consumption script.

Such repository is under the context of the EU-funded XGAIN Project. In specific, such work is under the umbrella of the dry-run lab testing actitivies for a Use Case (UC) where drones provide edge-based streaming services over 5G.

Setting Up the Environment

1. Install Dependencies:

   cd scripts
   ./install_dependencies.sh

2. Activate the Virtual Environment:

   source venv/bin/activate

3. Deactivate the Virtual Environment:

   deactivate

Run the experiment (video streaming transmission and KPIs extraction)

1. Run the Experiment:

   ./run_experiment.sh

Manual execution of the different scripts (Alternative)

1. Start the Streaming:

   ./start_streaming.sh

2. Monitor CPU and RAM Usage:

   ./monitor_cpu_ram.sh

3. Monitor Power Consumption:

   ./monitor_power_consumption.sh

4. Generate CPU and RAM Usage Plots:

   ./generate_plots_cpu_ram.sh

5. Generate Power Consumption Plot:

   ./generate_plot_power_consumption.sh

Notes

• For the power consumption KPI, configure the MQTT parameters in the monitor_power_consumption.sh script.
• For the streaming app, adjust the configuration parameters in the start_streaming.sh script as needed.
