Getting Started with Monk Logger

First, you need to install Monk Logger. It can be installed via pip:

  pip install monk-logger

API Examples

Below are some of the key APIs provided by Monk Logger along with code snippets to help you get started:

1. Basic Configuration

  import monk_logger

  logger = monk_logger.init_logger('my_app')

2. Logging Messages

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

3. Advanced Configuration

  config = {
      'level': 'DEBUG',
      'handlers': [
          {
              'type': 'file',
              'filename': 'my_app.log'
          },
          {
              'type': 'console'
          }
      ]
  }

  logger = monk_logger.init_logger('my_app', config=config)

4. Adding Custom Handlers

  from monk_logger.handlers import SMTPHandler

  smtp_handler = SMTPHandler(mailhost=('smtp.example.com', 587),
                            fromaddr='from@example.com',
                            toaddrs=['to@example.com'],
                            subject='Log Alert')

  logger.addHandler(smtp_handler)

5. Log Filtering

  class CustomFilter(monk_logger.Filter):
      def filter(self, record):
          return 'ignore' not in record.msg

  custom_filter = CustomFilter()
  logger.addFilter(custom_filter)

6. Contextual Logging

  with logger.contextual_log(user_id='12345'):
      logger.info('This log entry will include user_id in its context')

Application Example

Now, let’s integrate multiple APIs in a sample application:

  from flask import Flask
  import monk_logger

  app = Flask(__name__)

  config = {
      'level': 'DEBUG',
      'handlers': [
          {
              'type': 'file',
              'filename': 'my_app.log'
          },
          {
              'type': 'console'
          }
      ]
  }

  logger = monk_logger.init_logger('my_flask_app', config=config)

  @app.route('/')
  def home():
      logger.info('Home route accessed')
      return 'Welcome to the Home Page'

  @app.route('/error')
  def error():
      try:
          1/0
      except ZeroDivisionError as e:
          logger.error('An error occurred: %s', str(e))
      return 'Error Page'

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

With these comprehensive API examples and the integrated application, you’re well-equipped to leverage Monk Logger for all your logging needs. For further information and advanced usage, please refer to the official Monk Logger documentation.
