Filtering sensitive data

You have complete control over the data that Honeybadger reports when an error occurs. Before data is sent to Honeybadger, it is passed through a filter to remove sensitive fields and do other processing on the data. The default configuration is equivalent to:

config :honeybadger,
  filter: Honeybadger.Filter.Default,
  filter_keys: [:password, :credit_card]

This will remove any entries in the context, session, cgi_data and params that match one of the filter keys. The filter is case insensitive and matches atoms or strings.

If Honeybadger.Filter.Default does not suit your needs, you can implement your own filter. See the Honeybadger.Filter.Mixin module doc for details on implementing your own filter.

Filtering arguments

Honeybadger can show arguments in the stacktrace for FunctionClauseError exceptions. To enable argument reporting, set filter_args to false:

config :honeybadger, filter_args: false
