This module defines a Behaviour for filtering Sentry events. There is one callback to implement. The first argument will be the exception reported, and the second is the source. Events from Sentry.PlugCapture will have :plug as a source and events from Sentry.LoggerBackend will have :logger as the source. A custom source can also be specified by passing the event_source option to Sentry.capture_exception/2.

As an example, if you wanted to exclude any ArithmeticError exceptions:

defmodule MyApp.SentryEventFilter do
  @behaviour Sentry.EventFilter

  def exclude_exception?(%ArithmeticError{}, _source), do: true
  def exclude_exception?(_exception, _source), do: false
end

Alternatively, if you want to skip all non-500 exceptions in a Plug app:

defmodule MyApp.SentryEventFilter do
  @behaviour Sentry.EventFilter

  def exclude_exception?(exception, _) do
    Plug.Exception.status(exception) < 500
  end
end

Sentry uses Sentry.DefaultEventFilter by default.
