Python exception notifier for Airbrake

Installation

pybrake requires Python 3.4+.

pip install -U pybrake

Configuration

To configure the pybrake notifier you will need your Airbrake project's id and api_key, these are available from your project's settings page.

import pybrake


notifier = pybrake.Notifier(project_id=123,
                            project_key='FIXME',
                            environment='production')

Sending errors to Airbrake

try:
    raise ValueError('hello')
except Exception as err:
    notifier.notify(err)

Sending errors synchronously

By default, the notify function sends errors asynchronously using ThreadPoolExecutor and returns a concurrent.futures.Future, a synchronous API is also made available with the notify_sync function:

notice = notifier.notify_sync(err)
if 'id' in notice:
    print(notice['id'])
else:
    print(notice['error'])

Adding custom params

To set custom params you can build and send notice in separate steps:

notice = notifier.build_notice(err)
notice['params']['myparam'] = 'myvalue'
notifier.send_notice(notice)

You can also add custom params to every error notice before it's sent to Airbrake with the add_filter function.

def my_filter(notice):
    notice['params']['myparam'] = 'myvalue'
    return notice

notifier.add_filter(my_filter)

Ignoring notices

There may be some notices/errors thrown in your application that you're not interested in sending to Airbrake, you can ignore these using the add_filter function.

def my_filter(notice):
    if notice['context']['environment'] == 'development':
        # Ignore notices in development environment.
        return None
    return notice

notifier.add_filter(my_filter)

Filtering keys

With keys_blacklist option you can specify list of keys containing sensitive information that must be filtered out, e.g.:

notifier = pybrake.Notifier(
    ...
    keys_blacklist=[
        'password',           # exact match
        re.compile('secret'), # regexp match
    ],
)

Logging integration

pybrake provides a logging handler that sends your logs to Airbrake.

import logging
import pybrake


airbrake_handler = pybrake.LoggingHandler(notifier=notifier,
                                          level=logging.ERROR)

logger = logging.getLogger('test')
logger.addHandler(airbrake_handler)

logger.error('something bad happened')

Django integration

First you need to add your pybrake config to your Django settings.py file using your project's id and api_key.

AIRBRAKE = dict(
    project_id=123,
    project_key='FIXME',
)

The next step is activating the Airbrake middleware.

MIDDLEWARE = [
    ...
    'pybrake.django.AirbrakeMiddleware',
]

The last step is configuring the airbrake logging handler. After that you are ready to start reporting errors to Airbrake from your Django app.

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'airbrake': {
            'level': 'ERROR',
            'class': 'pybrake.LoggingHandler',
        },
    },
    'loggers': {
        'app': {
            'handlers': ['airbrake'],
            'level': 'ERROR',
            'propagate': True,
        },
    },
}

Flask integration

The Flask integration leverages Flask signals and therefore requires the blinker library.

from flask import Flask
import pybrake.flask



app = Flask(__name__)

app.config['PYBRAKE'] = dict(
    project_id=123,
    project_key='FIXME',
)
app = pybrake.flask.init_app(app)

aiohttp integration (python 3.5+)

Setup airbrake's middleware and config for your web application:

# app.py

from aiohttp import web
from pybrake.aiohttp import create_airbrake_middleware

airbrake_middleware = create_airbrake_middleware()

app = web.Application(middlewares=[airbrake_middleware])

app['airbrake_config'] = dict(
  project_id=123,
  project_key='FIXME',
  environment='production'  # optional
)

Also, you can pass custom handlers to create_airbrake_middleware:

# middlewares.py

import aiohttp_jinja2
from pybrake.aiohttp import create_airbrake_middleware


async def handle_404(request):
    return aiohttp_jinja2.render_template('404.html', request, {})


async def handle_500(request):
    return aiohttp_jinja2.render_template('500.html', request, {})


def setup_middlewares(app):
    airbrake_middleware = create_airbrake_middleware({
        404: handle_404,
        500: handle_500
    })

    app.middlewares.append(airbrake_middleware)

Disabling pybrake logs

The pybrake logger can be silenced by setting the logging level to logging.CRITICAL.

import logging


logging.getLogger("pybrake").setLevel(logging.CRITICAL)
