Solana RPC Performance Monitor

This project compares the response time of multiple RPC endpoints and then plots the results on a graph. A live example site can be checked out here: https://monitor.solanavibestation.com

🚀 Features

• Monitors multiple Solana RPCs concurrently (async, non-blocking)
• Stores 1 hour of RPC metrics
• Calculates RPC response time metrics and visualizes this data on a time chart
• Web UI served with Axum (/static/index.html)

🛠 Installation & Setup

1️⃣ Clone the Repository

2️⃣ Install Rust (If Not Installed)

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Verify installation:

rustc --version
cargo --version

3️⃣ Install Dependencies

sudo apt install pkg-config
sudo apt install librust-openssl-dev

cargo build

⚙️ Configuration

Edit config.toml

Before running the project, configure the Solana RPC endpoints in config.toml:

[rpc]
endpoints = [
    { url = "https://api.mainnet-beta.solana.com", nickname = "Mainnet" },
    { url = "https://api.devnet.solana.com", nickname = "Devnet" },
    { url = "https://solana-api.projectserum.com", nickname = "ProjectSerum" },
    { url = "https://rpc.ankr.com/solana", nickname = "Ankr" }
]

[server]
listen_ip = "0.0.0.0"
port = 3000

• You can add/remove endpoints as needed.
• Each endpoint must have a nickname for easier identification.
• You can set the ip and port or leave at default

▶️ Running the Program

Run the program with:

cargo run

You can overide the host with the below:

cargo run -- --listen-ip 127.0.0.1 --port 5000

Use this for quick build:

cargo check

Then run:

cargo run

It will start monitoring Solana RPCs and provide API access.

Example output:

📊 Web UI

A basic web interface is available at:

http://localhost:3000/static/index.html

🛠 Troubleshooting

❌ rocksdb: IO error

Fix: Ensure the database directory is writable and restart the application.

❌ Server not starting

Fix: Check if port 3000 is free or specify another:
