supertracer 0.1.3

A powerful and easy-to-use logging and tracing library for FastAPI applications.

SuperTracer

SuperTracer is a powerful and easy-to-use logging and tracing library for FastAPI applications. It provides a real-time dashboard to monitor requests, analyze performance, and debug issues with ease.

Features

• Real-time Dashboard: Monitor incoming requests and logs as they happen.
• Comprehensive Logging: Captures request/response bodies, headers, status codes, latency, and more.
• Multiple Storage Backends: Support for In-Memory, SQLite, and PostgreSQL.
• Advanced Filtering: Filter logs by method, status code, latency, date, and content.
• Metrics & Analytics: Visualize request rates, error rates, and latency distributions.
• Secure: Built-in authentication for the dashboard and API.
• Easy Configuration: Configure via JSON file or Python objects.

Installation

pip install supertracer

Quick Start

Integrate SuperTracer into your FastAPI application in just a few lines of code:

from fastapi import FastAPI
from supertracer import SuperTracer

app = FastAPI()

# Initialize SuperTracer (defaults to In-Memory storage)
tracer = SuperTracer(app)

@app.get("/")
def read_root():
    return {"Hello": "World"}

Now run your application and visit /supertracer/logs to see the dashboard!

Storage Backends

SuperTracer supports different storage backends. By default, it uses an in-memory connector. To use a persistent database, pass the connector instance:

SQLite

from supertracer import SuperTracer, SQLiteConnector

# ... app setup ...

connector = SQLiteConnector("requests.db")
tracer = SuperTracer(app, connector=connector)

PostgreSQL

from supertracer import SuperTracer, PostgreSQLConnector

# ... app setup ...

connector = PostgreSQLConnector(
    host="localhost",
    port=5432,
    database="supertracer_db",
    user="your_username",
    password="your_password"
    sslmode="prefer"
)
tracer = SuperTracer(app, connector=connector)

Configuration

SuperTracer is highly configurable. You can use a supertracer.config.json file in your project root or pass options programmatically.

Using supertracer.config.json

Create a file named supertracer.config.json to configure logging, metrics, auth, and more:

{
  "logger_options": {
    "level": 20,
    "format": "%(message)s"
  },
  "metrics_options": {
    "enabled": true,
    "history_limit": 1000
  },
  "capture_options": {
    "capture_request_body": true,
    "max_request_body_size": 10240,
    "capture_response_body": true
  }
}

Programmatic Configuration

You can also pass options directly:

from supertracer import SuperTracer, SupertracerOptions, LoggerOptions

options = SupertracerOptions(
    logger_options=LoggerOptions(level=10), # DEBUG
)

tracer = SuperTracer(app, options=options)
