Prometheus + Grafana Monitor Setup

Prometheus + Grafana Monitor Setup with Docker-Compose

About

You can remove stuff you don't need. This docker-compose setup includes:

• prometheus:
  • Prometheus is a systems and service monitoring system. It collects metrics from configured targets at given intervals.
• grafana
  • Grafana is a complete observability stack that allows you to monitor and analyze metrics, logs and traces. It's the web interface that shows the graphs. 🙂
• cadvisor
  • cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers.
• node_exporter
  • Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.
• blackbox
  • The blackbox exporter allows blackbox probing of endpoints over HTTP, HTTPS, DNS, TCP and ICMP.
• json_exporter
  • A prometheus exporter which scrapes remote JSON by JSONPath. Log REST APIs.

Setup

• Check the config files in /config
• docker-compose up
• Port 9191 is exposed on localhost, use nginx or similar to proxy to grafana:

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name g.yourdomain.com;

    location / {
        proxy_pass http://127.0.0.1:9191/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Usage

Go to grafana dashboard, login with admin:admin and change the password. Play around with it and import some dashboards and panels. Go to the dashboard library, copy the id and import it. Set up alerts to telegram, discord or slack.
