OS Metrics

The system includes two services:

• metrics_collector - collects OS metrics (CPU, memory, disk) and sends it to Kafka topic

• metrics_loader - consumes Kafka topic and saves to Postgres DB

How to run

Several environment variables needs to be setup, mainly Postgres and Kafka configuration. Look at settings.py in metrics_collector and metrics_loader for more info.

After updating docker-compose.yml with environment variables run:

docker-compose up

It will start both collector and loader.

Tests

To run tests for collector:

docker-compose run metrics_collector bash
pytest metrics_collector/tests.py

To run metrics loader tests:

docker-compose run metrics_loader bash
pytest metrics_loader/tests.py
