Reducing Noise

Sometimes there are errors that you would rather not send to Honeybadger because they are not actionable or are handled internally.

Ignoring errors by class name

By default Honeybadger will be notified when any error occurs. To override this configuration in order not to send out errors to Honeybadger, set excluded_exceptions in honeybadger.configure.

The excluded_exceptions configuration accepts a list of exception class names (as strings) to exclude:

python

from honeybadger import honeybadger

honeybadger.configure(excluded_exceptions=["ZeroDivisionError", "ValueError"])

Exceptions are skipped when the exception's class name is found in the excluded_exceptions list.

Dynamic ignoring errors with before_notify

For more complex scenarios, you can use a before_notify handler to conditionally ignore errors:

python

from honeybadger import honeybadger

def filter_errors(notice):
    # Skip connection errors during maintenance windows
    if notice.error_class == 'ConnectionError' and is_maintenance_mode():
        return False

    return notice

honeybadger.configure(before_notify=filter_errors)

Returning False from the handler will skip the notification entirely.
