Spark REST

Spark-REST

Spark-REST is a lightweight Minecraft Forge 1.20.1 mod that exposes server performance metrics — provided by the Spark profiler — through a simple REST API.
Designed for server administrators who want to monitor TPS, MSPT, CPU usage, and other performance data using external dashboards, bots, or monitoring tools.

🚀 Features

• Built-in HTTP server that exposes live performance metrics
• Retrieves data directly from Spark
• Metrics include: TPS (10s, 1m, 5m, 15m), MSPT, CPU usage, etc…
• Fully configurable port and endpoint
• Extremely lightweight and safe for production servers

📦 Requirements

• Minecraft Forge 1.20.1
• Spark profiler installed on the server (created by Lucko)
• Java 17 or higher

Note: Spark-REST does not include Spark. You must install Spark separately.

⚙️ Installation

1. Download spark-rest.jar
2. Place it in your server’s /mods/ folder
3. Ensure the Spark mod is also installed
4. Start the server to generate the configuration file

📝 Configuration

• After the first launch, the configuration file is created at:
• config/spark_rest-common.toml
• Example:
  • [general]
port = 8080
endpoint = "metrics"
enabled = true

🔗 REST API

• Access your metrics from any browser, bot, or dashboard:
• http://{server-ip}:{port}/{endpoint};
• Example:
• http://localhost:8080/metrics
• Example JSON response:
  • > { “tps_10s”: 20.0, “tps_1m”: 19.95, “tps_5m”: 19.87, “tps_15m”: 19.76, “mspt_1m”: 12.4, “cpu”: 45.2 }

❓FAQ

• Spark-REST returns no metrics or errors
          Make sure Spark is installed and running — Spark-REST depends on Spark’s API.
• The port is already in use
          Change the port value in the config file.
