I will take an example of an application for blog creation and listing API using Python Django framework. First, we have to install the APM agent for Python Django:

pip install elastic-apm

Then, we have to configure the agent with the Django application; we need to make the following changes in the settings.py file:

# Add the agent to the installed apps
INSTALLED_APPS = (
  'elasticapm.contrib.django',
  # ...
)

ELASTIC_APM = {
  # Set required service name. Allowed characters:
  # a-z, A-Z, 0-9, -, _, and space
  'SERVICE_NAME': 'django application',

  # Use if APM Server requires a token
  'SECRET_TOKEN': 'mysecrettoken',

  # Set custom APM Server URL (default: http://localhost:8200)
  'SERVER_URL': 'http://localhost:8200',
}

# To send performance metrics, add our tracing middleware...
