ExceptionDog
Exception dog is a simple exception notifier gem that pushes exceptions out to Dotadog as metric events. You can set up rules within datadog to push new occurrences of the events into slack for instance, to have a reasonably good exception service.
Installation
Add this line to your application's Gemfile:
gem 'exception_dog'Usage
exception_dog can be configured to use the datadog agent or the public cloud API.
You can configure in an initialiser, for example: in a file config/initializers/exception_dog.rb
Datadog Agent Configuration Example
ExceptionDog.configure do |config|
config.environment = ENV["RAILS_ENV"]
config.notifier = Rails.env.test? ? "ExceptionDog::LogNotifier" : "ExceptionDog::AgentNotifier"
config.agent_host = 'localhost'
config.agent_port = 8125
config.logger = Rails.logger
config.service_name = Rails.application.class.parent.name.underscore
config.ignore_exceptions = ["ActionController::RoutingError"]
end
Datadog API configuration
ExceptionDog.configure do |config|
config.environment = ENV["RAILS_ENV"]
config.api_key = ENV["DATA_DOG_API_KEY"]
config.notifier = Rails.env.test? ? "ExceptionDog::LogNotifier" : "ExceptionDog::HttpNotifier"
config.logger = Rails.logger
config.service_name = Rails.application.class.parent.name.underscore
config.ignore_exceptions = ["ActionController::RoutingError"]
end
Middleware Configuration You can set up a simple middleware to catch and report exceptions for Rack based apps.
