Welcome to Everlogger: Your Ultimate Tool for Efficient Logging

In this guide, we will introduce Everlogger, a powerful and efficient logging system for your applications. We will explore dozens of useful APIs with code snippets and provide a comprehensive app example using these APIs.

Understanding Everlogger

Everlogger is a robust and feature-rich logging library that enables seamless logging within your applications. It supports a variety of logging levels and formats to help you track and debug your applications efficiently.

Basic Setup

The following code snippet demonstrates how to install and set up Everlogger in your project:

 pip install everlogger 

 import everlogger
# Create a logger instance logger = everlogger.get_logger('my_logger')
# Set logging level logger.set_level(everlogger.INFO) 

Logging Messages

Everlogger supports multiple logging levels, here’s how to log messages at different levels:

 logger.debug('This is a debug message') logger.info('This is an information message') logger.warning('This is a warning message') logger.error('This is an error message') logger.critical('This is a critical message') 

Adding Context to Logs

Sometimes, it’s useful to add context to your logs:

 context = {'user': 'john_doe', 'action': 'login'} logger.info('User action logged', extra=context) 

Handling Exceptions

Everlogger makes it easy to log exceptions:

 try: 1 / 0 except ZeroDivisionError: logger.exception('An error occurred') 

Configuring Logger

Customizing your logger is simple:

 config = { 'version': 1, 'formatters': { 'default': { 'format': '%(asctime)s - %(name)s - %(levelname)s - %(message)s' } }, 'handlers': { 'file': { 'class': 'logging.FileHandler', 'filename': 'app.log', 'formatter': 'default' } }, 'loggers': { 'my_logger': { 'handlers': ['file'], 'level': 'INFO' } } } everlogger.dictConfig(config) 

Rotating File Handler

Ensure your log files are rotated to avoid large file sizes:

 from everlogger.handlers import RotatingFileHandler
handler = RotatingFileHandler('app.log', maxBytes=2000, backupCount=5) logger.addHandler(handler) 

Integrating Everlogger with a Flask App

Here is a comprehensive example of integrating Everlogger with a Flask application:

 from flask import Flask import everlogger
app = Flask(__name__)
# Configure Everlogger logger = everlogger.get_logger('flask_app') logger.set_level(everlogger.INFO)
@app.route('/') def home(): logger.info('Home endpoint was called') return 'Welcome to the Everlogger Flask App!'
@app.route('/error') def error(): try: 1 / 0 except ZeroDivisionError: logger.exception('An error occurred in the error endpoint') return 'Error endpoint encountered an error', 500
if __name__ == '__main__': app.run(debug=True) 

By following this guide, you can efficiently integrate Everlogger into your applications, enhancing your ability to debug and monitor them. Happy Logging!
