PowerNap: Your Eco-Friendly CPU Monitor

Welcome to PowerNap! This is a Python-based tool that keeps an eye on your CPU usage and smartly adjusts the CPU governor to optimize power consumption. It's like having a personal assistant for your CPU, but one that's eco-friendly!

Features

• Real-time CPU Usage Monitoring: PowerNap keeps track of your CPU usage in real time.
• Smart Governor Adjustment: PowerNap adjusts the CPU governor based on the current CPU usage and power cost, helping you save power.

1. Clone this repository to your local machine:

   git clone https://github.com/yourusername/PowerNap.git

2. Navigate to the cloned repository:

   cd PowerNap

3. Create a Python virtual environment and activate it:

   python3 -m venv env
   source env/bin/activate

4. Install the required Python packages:

   pip install -r requirements.txt

Configuration

The powernap.conf file contains the following configuration options:

• CostConstants: This section defines the cost thresholds for high, mid, and low electricity prices.

  [CostConstants]
  HIGH_COST = 1.0
  MID_COST = 0.8
  LOW_COST = 0.5

• AreaCode: This section specifies the area code for which to fetch electricity prices.

  [AreaCode]
  AREA = SE3

• SleepInterval: This section specifies the interval (in seconds) at which the script should sleep between iterations of the main loop.

  [SleepInterval]
  INTERVAL = 60

• DataRetention: This section configures data retention settings. DAYS is the number of days to retain data, and ENABLED is a boolean indicating whether data retention is enabled.

  [DataRetention]
  DAYS = 1
  ENABLED = True

• CommitInterval: This section specifies the interval (in minutes) at which data should be committed to the database.

  [CommitInterval]
  INTERVAL = 5

• UsageCalculation: This section specifies the method for calculating CPU usage. The METHOD can be set to either 'average' or 'median'.

  [UsageCalculation]
  METHOD = median

Systemd Service

To run PowerNap as a systemd service, create a service file powernap.service:

[Unit]
Description=PowerNap Service
After=network.target

[Service]
ExecStart=/path/to/your/python/env/bin/python -u /path/to/your/script/powernap.py
Restart=always

[Install]
WantedBy=multi-user.target
