Docker Monitoring

This repository contains the docker-compose.yml and configuration files to deploy Grafana for both centralized logging and system metrics to discovers and monitors all services running on your Docker host.

💻 Tech Stack

Visualization

• Grafana: The unified dashboard for visualizing, querying, and alerting on all your logs (from Loki) and metrics (from Prometheus) in one place.

Logging

• Loki: The log aggregation database, built for efficiently storing and searching log text.
• Promtail: The agent that discovers, collects, and "pushes" Docker container logs to Loki.

Metrics

• Prometheus: The time-series database for collecting and storing all numeric metrics by pulling scraping data from exporters.
• cAdvisor: An agent that "exposes" real-time performance metrics (CPU, RAM, network) from all running Docker containers for Prometheus to "pull".
• Node Exporter: An agent that "exposes" hardware and OS metrics from the host VPS (CPU, RAM, and disk usage) for Prometheus to "pull".
