Defined in:
lib/rails/rack/silence_request.rb

Overview

Allows you to silence requests made to a specific path. This is useful for preventing recurring requests like health checks from clogging the logging. This middleware is used to do just that against the path /up in production by default.

Example:

config.middleware.insert_before \
  Rails::Rack::Logger, Rails::Rack::SilenceRequest, path: "/up"

This middleware can also be configured using ‘config.silence_healthcheck_path = “/up”` in Rails.
