rollbar 0.5.5

Rollbar generic python library

pyrollbar is a generic library for reporting exceptions and other messages to Rollbar:

import rollbar, sys
rollbar.init('YOUR_ACCESS_TOKEN', 'production')  # access_token, environment

try:
    main_app_loop()
except IOError:
    rollbar.report_message('Got an IOError in the main loop', 'warning')
except:
    # catch-all
    rollbar.report_exc_info(sys.exc_info())

Requirements

pyrollbar requires:

• Python 2.6 or 2.7

• requests 0.12+

• a Rollbar account

Installation

Install using pip:

pip install rollbar

Configuration

For generic Python or a non-Django/non-Pyramid framework, follow these instructions:

Somewhere in your initialization code, call rollbar.init() with your access_token:

rollbar.init('YOUR_ACCESS_TOKEN_HERE', environment='production')

Other options can be passed as keyword arguments. See the reference below for all options.

If you are integrating with Django, follow these instructions:

1. In your settings.py, add 'rollbar.contrib.django.middleware.RollbarNotifierMiddleware' as the last item in MIDDLEWARE_CLASSES:

   MIDDLEWARE_CLASSES = (
       # ... other middleware classes ...
       'rollbar.contrib.django.middleware.RollbarNotifierMiddleware',
   )

2. Add these configuration variables in settings.py:

   ROLLBAR = {
       'access_token': 'YOUR_ACCESS_TOKEN_HERE',
       'environment': 'development' if DEBUG else 'production',
       'branch': 'master',
       'root': '/absolute/path/to/code/root',
   }

If you are integrating with Pyramid, follow these instructions:

1. In your ini file (e.g. production.ini), add rollbar.contrib.pyramid to the end of your pyramid.includes:

   [app:main]
   pyramid.includes =
       pyramid_debugtoolbar
       rollbar.contrib.pyramid

2. Add these rollbar configuration variables:

   [app:main]
   rollbar.access_token = YOUR_ACCESS_TOKEN_HERE
   rollbar.environment = production
   rollbar.branch = master
   rollbar.root = %(here)s

The above will configure rollbar to catch and report all exceptions that occur in your Pyramid app. However, if there are any middleware applications that wrap your app, Rollbar will not be able to catch exceptions.

In order to catch exceptions from Pyramid and middleware code, you will need to create a pipeline where the rollbar middleware wraps your Pyramid app.

• Change your ini file to use a pipeline:

  From
  
  [app:main]
  ...
  
  To
  
  [pipeline:main]
  pipeline =
      rollbar
      YOUR_APP_NAME
  
  [app:YOUR_APP_NAME]
  pyramid.includes =
      pyramid_debugtoolbar
      rollbar.contrib.pyramid
  
  [filter:rollbar]
  access_token = YOUR_ACCESS_TOKEN_HERE
  environment = production
  branch = master
  root = %(here)s

Unfortunately, the rollbar tween and the rollbar filter configurations contains duplicated information. We’ll look into fixing this in future versions.

Usage

The Django and Pyramid integration will automatically report uncaught exceptions to Rollbar.

Call rollbar.report_exc_info() to report an exception, or rollbar.report_message() to report an arbitrary string message. See the docstrings for more info.

Configuration reference

access_token

Access token from your Rollbar project

handler

One of:

• blocking – runs in main thread

• thread – spawns a new thread

• agent – writes messages to a log file for consumption by rollbar-agent

default: thread

environment

Environment name. Any string up to 255 chars is OK. For best results, use “production” for your production environment.

root

Absolute path to the root of your application, not including the final /.

branch

Name of the checked-out branch.

default: master

agent.log_file

If handler is agent, the path to the log file. Filename must end in .rollbar

endpoint

URL items are posted to.

default: https://api.rollbar.com/api/1/item/

scrub_fields

List of field names to scrub out of POST. Values will be replaced with astrickses. If overridiing, make sure to list all fields you want to scrub, not just fields you want to add to the default. Param names are converted to lowercase before comparing against the scrub list.

default ['passwd', 'password', 'secret', 'confirm_password', 'password_confirmation']
