Setting Up a Monitoring Stack with Grafana, Prometheus, Node Exporter, cAdvisor and Loki in Docker Compose, Exposed via NGINX

This guide provides instructions on setting up a comprehensive monitoring stack using Grafana, Prometheus, Node Exporter, cAdvisor and Loki. These components are orchestrated with Docker Compose and exposed via an NGINX reverse proxy, making them accessible through a single domain.

Components

• Grafana: The analytics and monitoring solution with support for multiple data sources, including Prometheus.
• Prometheus: The monitoring and alerting toolkit, collecting metrics from configured targets at specified intervals.
• Node Exporter: A Prometheus exporter for hardware and OS metrics exposed by *NIX kernels.
• cAdvisor: Analyzes resource usage and performance characteristics of running containers.

Create repository for snapshots

• The location is the path where the snapshots will be stored, this path need to be set in the elasticsearch.yml file in the path.repo property
• example: path.repo: ["/usr/share/elasticsearch/backup"]
• After setting the path.repo property in the elasticsearch.yml file, restart the elasticsearch service

curl -XPUT -k -u elastic:changeme "https://localhost:9200/_snapshot/repository_backups" -H 'Content-Type: application/json' -d '{
  "type": "fs",
  "settings": {
    "location": "/usr/share/elasticsearch/backup"
 }
