Prometheus metrics exporter for Marzban panel

Marzban Metrics Exporter

Marzban Metrics Exporter is an application designed to collect and export metrics from the Marzban VPN management panel. This exporter enables monitoring of various aspects of the VPN service, such as node status, traffic, system metrics, and user information, making the data available for the Prometheus monitoring system.

Features

• Node Status Monitoring: Tracks the connection status of VPN nodes, indicating whether each node is connected or not.
• Traffic Metrics: Provides detailed metrics on uplink and downlink traffic for each VPN node.
• System Health Monitoring: Reports on system health indicators such as total and used memory, CPU cores, CPU usage, total number of users, active users, and bandwidth metrics.
• User Activity Tracking: Monitors user activity, including data limits, used traffic, lifetime used traffic, and online status within the last 2 minutes.
• Version and Start Time Information: Includes core version information and whether the core service has started successfully.
• Configurable via Environment Variables and Command-line Arguments: Allows customization and configuration through both environment variables and command-line arguments, making it easy to adjust settings.
• Support for Multiple Architectures: Docker images are available for multiple architectures, including AMD64 and ARM64, ensuring compatibility across various deployment environments.
• Optional BasicAuth Protection: Provides the option to secure the metrics endpoint with BasicAuth, adding an additional layer of security.
• Integration with Prometheus: Designed to integrate seamlessly with Prometheus, facilitating easy setup and configuration for monitoring Marzban VPN services.
• Simplifies VPN Monitoring: By providing a wide range of metrics, it simplifies the process of monitoring and managing VPN services, enhancing visibility into system performance and user activity.

Usage

CLI

/marzban-exporter --marzban-base-url=<your-marzban-panel-url> --marzban-username=<your-marzban-username> --marzban-password=<your-marzban-password>

Docker

docker run -d \
  -e MARZBAN_BASE_URL=<your-marzban-panel-url> \
  -e MARZBAN_USERNAME=<your-marzban-username> \
  -e MARZBAN_PASSWORD=<your-marzban-password> \
  -p 9090:9090 \
  kutovoys/marzban-exporter

Docker Compose

version: "3"
services:
  marzban-exporter:
    image: kutovoys/marzban-exporter
    environment:
      - MARZBAN_BASE_URL=<your-marzban-panel-url>
      - MARZBAN_USERNAME=<your-marzban-username>
      - MARZBAN_PASSWORD=<your-marzban-password>
    ports:
      - "9090:9090"

Integration with Prometheus

To collect metrics with Prometheus, add the exporter to your prometheus.yml configuration file:

scrape_configs:
  - job_name: "marzban_exporter"
    static_configs:
      - targets: ["<exporter-ip>:9090"]

Ensure to replace <your-marzban-panel-url>, <your-marzban-username>, <your-marzban-password>, and <exporter-ip> with your actual information.

TODO

• ✅ Ensure all necessary environment variables are set and validate them at startup.
• ✅ Implement command line arguments for passing configuration options.
• ⏳ Create a Grafana dashboard tailored for the Marzban Metrics Exporter to visualize the collected metrics effectively.
