This project sets up a robust DevOps environment using Docker and Traefik as a reverse proxy to route traffic to various services including Sonatype Nexus, WordPress, Prometheus, Grafana, and a custom Nginx server. It is designed to provide a comprehensive development, CI/CD, and monitoring platform.

• Traefik: Serves as the reverse proxy and load balancer with automatic SSL certificate resolution via ACME, detailed logging, and API access for configuration.
• Sonatype Nexus: Used for storing artifacts and as a Docker registry.
• WordPress: Provides a blogging platform, connected to a MariaDB database.
• MariaDB: SQL database used by WordPress.
• Prometheus: Monitoring system with time series data storage.
• Grafana: Analytics and monitoring platform that integrates with Prometheus.
• Nginx: Web server configured to serve as the front-end for hosted applications.
• Fluentd: Logging architecture to capture and process Nginx logs.

• Docker installed on your machine.
• Docker Compose installed on your machine.

1. Clone the repository:

   git clone https://github.com/alishazaee/traefik
   cd traefik
   

2. Setup the project using docker-compose:

   docker-compose up -d

3. Generate simulated Traffic:

   cd traffic-generator
   chmod 777 generator.sh
   ./generator.sh
   

This project includes comprehensive monitoring solutions for Nginx using Grafana dashboards. Through the integration of Prometheus and Nginx exporter, as well as log data captured by Fluentd, we provide real-time insights into the performance and health of the Nginx web server.

The Nginx Exporter Dashboard gives a visual representation of critical metrics from the Nginx web server, such as:

• Processed Connections: Counts the total number of connections processed by Nginx, including accepted and handled connections.
• Active Connections: Shows the number of currently active connections, along with details on connections that are reading, writing, or waiting.
• Total Requests: Tracks the total number of HTTP requests that the server has received over time.

This dashboard is essential for detecting performance bottlenecks, understanding user behavior, and ensuring high availability.

• Latency: Measures the time taken to process HTTP GET requests. The graph provides percentile distributions (P50, P90, P99) for detailed latency analysis.
• Traffic: Displays the rate of HTTP requests over time, broken down by request paths. This helps in identifying the traffic patterns and the most frequently accessed endpoints.
• Availability: Represents the percentage of non-error responses (excluding 4xx and 5xx status codes), giving a quick overview of the server's health.

Fluentd collects and aggregates logs from Nginx, and this data is visualized on the Fluentd Nginx Log Dashboard, providing insights into:

Monitoring these metrics is vital for maintaining operational performance and can assist in early detection of irregular patterns that could indicate issues.

To view the dashboards:

1. Ensure that Prometheus and Grafana are running via the Docker Compose setup provided in this project.
2. Access Grafana through http://grafana.alishazaee.ir and log in with your credentials. ( You can change this domain in the docker-compose file )
3. Navigate to the dashboard panel to view the Nginx Exporter and Fluentd dashboards.

Note: Replace alishazaee.ir with your actual domain name and ensure that the Nginx Exporter and Fluentd are configured correctly to send metrics to Prometheus.
