Flask module for submitting timings and exceptions to Datadog

Project description

A Flask module pushing exceptions to Datadog


  • Pushing exceptions to Datadog;
  • Blacklist for headers or data as list of XPATH style strings (you may have some headers you do not want to publish for privacy, or maybe some body fields you do not need to display - e.g.: a base64 blob).


Using pip:

$ pip install flask_breathalyzer[datadog]


When opening an Issue, please add few lines of code as failing test, or -better- open its relative Pull request adding this test to our test suite.

Quick example

Let’s create a new virtualenv with all we need:

$ virtualenv example
$ source example/bin/activate
$ pip install pytest flask_breathalyzer[datadog]

As second step, we create a test file as the following one:

from flask import Flask
import datadog

from flask_breathalyzer import Breathalyzer

def test_example():

    app = Flask(__name__)

    def boom():

    # from
    options = {
        'api_key': 'your-datadog-api-key',
        'app_key': 'your-datadog-app-key'

    ba = Breathalyzer(app, **options)
    response = test_client.get('/')
    assert response.status == '500 INTERNAL SERVER ERROR'
    assert b'<title>500 Internal Server Error</title>' in
    assert response.mimetype == 'text/html'
    assert isinstance(ba.last_event_id, int)  # your exception is now on Datadog with this ID

Let’s fire our example test:

$ py.test
