Quick Start 🏁

1. Start the LiteMon server

litemon --port 8000

2. Use LiteMon in your App

from flask import Flask
from litemon import configure_client, monitor

app = Flask(__name__)

# Configure LiteMon client to push metrics to the server
configure_client(server_url="http://127.0.0.1:8000", push_interval=2)

@monitor
def greet():
    return "Hello! Welcome to the server."

@monitor
def bye():
    return "Goodbye! See you soon."

@app.route('/greet', methods=['GET'])
def greet_route():
    return greet()

@app.route('/bye', methods=['GET'])
def bye_route():
    return bye()

if __name__ == '__main__':
    app.run(port=5050, debug=True)

3. Monitor Metrics Fetch current metrics:

curl http://127.0.0.1:8000/metrics

• Your Flask app → http://127.0.0.1:5050
• LiteMon metrics dashboard → http://127.0.0.1:8000/metrics

4. Reset Metrics Clear all collected metrics:

curl -X POST http://127.0.0.1:8000/reset
