docker-exporter

docker-exporter is a Prometheus exporter that exposes detailed metrics about running Docker containers. It provides information on CPU usage, memory usage, network usage, I/O, volume size for each container, as well as for child processes.

Features

• Detailed per-container metrics:
  • CPU usage (user, kernel)
  • Memory usage
  • Network usage (bytes received/sent)
  • I/O usage (bytes read/written)
  • Optional volume metrics
  • Optional child process metrics
• Flexible configuration:
  • Ability to filter monitored containers (Docker Compose only)

Installation and Usage

Prerequisites

• Docker installed and running
• Prometheus installed and configured
