Sentinel

An experimental API for gathering Linux server / Docker Engine metrics.

This will be used in coolify.io.

Features

Server

• CPU usage
• Memory usage
• Disk usage

Containers

• CPU usage
• Memory usage
• Network usage

Usage

Start as a container:

docker run -d -v ./logs:/app/logs -v ./metrics:/app/metrics -v /var/run/docker.sock:/var/run/docker.sock --pid host --name sentinel ghcr.io/coollabsio/sentinel:latest

# You can expose port 8888 to access the API
# By default, the API is only available in the container, so you need docker exec to access it.

API

Server

• GET /api/cpu - Get CPU usage.
• GET /api/memory - Get memory usage.
• GET /api/disk - Get disk usage.

Containers

• GET /api/containers - Get all containers with metrics and labels.

Roadmap

• Able to save metrics to a database / filesystem in a time series format.
