Configuration Reference

This is the configuration reference table for the pyrollbar SDK. The source code itself can be found on the Github repository.




Access token from your Rollbar project


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


Name of the checked-out branch.

Default: master


A string describing the current code revision/version (i.e. a git sha). Max 40 characters.

Default: None


Controls whether or not Rollbar will report any data

Default: True


URL items are posted to.



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


List of tuples in the form (class, level) where class is an Exception class you want to always filter to the respective level. Any subclasses of the given class will also be matched.

Valid levels: 'critical', 'error', 'warning', 'info', 'debug' and 'ignored'.

Use 'ignored' if you want an Exception (sub)class to never be reported to Rollbar.

Any exceptions not found in this configuration setting will default to 'error'.

Django example (and Django default):

from django.http import Http404

    'exception_level_filters': [
        (Http404, 'warning')

In a Pyramid ini file, define each tuple as an individual whitespace delimited line, for example:

rollbar.exception_level_filters =
    pyramid.exceptions.ConfigurationError critical


The method for reporting rollbar items to

One of:

  • default -- uses default handler (thread for sync reporting and async for async reporting)
  • blocking -- runs in main thread
  • thread -- spawns a new thread
  • async -- uses default (httpx) async handler to send the payload
  • agent -- writes messages to a log file for consumption by rollbar-agent
  • httpx -- uses the HTTPX async library to send the payload
  • tornado -- uses the Tornado async library to send the payload
  • gae -- uses the Google AppEngineFetch library to send the payload
  • twisted -- uses the Twisted event-driven networking library to send the payload

Default: default


Configuration for collecting local variables. A dictionary:

  • enabled
    • If True, variable values will be collected for stack traces. Default True.
  • safe_repr
    • If True, non-built-in objects will be serialized into just their class name. If False repr(obj) will be used for serialization. Default True.
  • sizes
    • Dictionary of configuration describing the max size to repr() for each type.
      • maxdict: Default 10
      • maxarray: Default 10
      • maxlist: Default 10
      • maxtuple: Default 10
      • maxset: Default 10
      • maxfrozenset: Default 10
      • maxdeque: Default 10
      • maxstring: Default 100
      • maxlong: Default 40
      • maxother: Default 100
  • safelisted_types
    • A list of type objects, (e.g. type(my_class_instance) or MyClass) that will be serialized using
      repr(). Default []
  • scrub_varargs
    • If True, variable argument values will be scrubbed. Default True.


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


List of sensitive field names to scrub out of request params and locals. Values will be replaced with asterisks. If overriding, 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: ['pw', 'passwd', 'password', 'secret', 'confirm_password', 'confirmPassword', 'password_confirmation', 'passwordConfirmation', 'access_token', 'accessToken', 'auth', 'authentication']


Timeout for any HTTP requests made to the Rollbar API (in seconds).

Default: 3


When True, logging.basicConfig() will be called to set up the logging system. Set to False to skip this call. If using Flask, you'll want to set to False. If using Pyramid or Django, True should be fine.

Default: True


List of fields treated as URLs and scrubbed.

Default ['url', 'link', 'href']


If True, network requests will fail unless encountering a valid certificate. Default True.


A list of key prefixes (as tuple) to apply our shortener transform to. Added to built-in list:

    ('body', 'request', 'POST'),
    ('body', 'request', 'json')

If locals.enabled is True, extra keys are also automatically added:

    ('body', 'trace', 'frames', '*', 'code'),
    ('body', 'trace', 'frames', '*', 'args', '*'),
    ('body', 'trace', 'frames', '*', 'kwargs', '*'),
    ('body', 'trace', 'frames', '*', 'locals', '*')

Default: []


If True, suppresses the warning normally shown when rollbar.init() is called multiple times.

Default: False.


If equal to True, we will attempt to capture the full client IP address from a request.

If equal to the string anonymize, we will capture the client IP address, but then semi-anonymize it by masking out the least significant bits.

If equal to False, we will not capture the client IP address from a request.

Default: True


If set to True, we will attempt to enrich person data with an email address if available.

Default: False


If set to True, we will attempt to enrich person data with a username if available.

Default: False
