Prerequisites

To complete the "Monitoring Ruby on Rails with Raygun" tutorial, you will need the following prerequisites:

• A basic understanding of Ruby on Rails development
• A working Ruby on Rails application
• A Raygun account (you can sign up for a free trial if you don't have one)
• The Raygun Ruby gem installed in your application
• A text editor or integrated development environment (IDE) for editing your application's code
• A command-line interface (CLI) for running commands and managing your application
• Basic knowledge of the command line and terminal commands
• Familiarity with the Ruby on Rails command line interface (CLI) and how to run Rails commands
• Basic knowledge of how to configure and manage a Ruby on Rails application's dependencies and environment variables.

Ruby on Rails Raygun step by step setup and configuration

Integrating Raygun into a Ruby on Rails project is a straightforward process that involves installing the Raygun Ruby gem and configuring it to work with your application. To get started, you will need to add the Raygun gem to your application's Gemfile and run the bundle install command to install it.

# Gemfile
gem 'raygun4ruby'

Once you have installed the Raygun gem, you will need to configure it to work with your application. To do this, you will need to create an initializer file in your application's config/initializers directory. In this file, you can configure the Raygun gem with your Raygun API key and any other settings you want to customize.

# config/initializers/raygun.rb
Raygun.setup do |config|
  config.api_key = 'YOUR_RAYGUN_API_KEY'
  config.filter_parameters = Rails.application.config.filter_parameters
  config.enable_reporting = !Rails.env.development?
end

In the above code block, replace YOUR_RAYGUN_API_KEY with your actual Raygun API key. You can find your API key in your Raygun account settings.

Once you have configured the Raygun gem, you can start using it to monitor your application. To test that everything is working correctly, you can add a test error to your application and ensure that it is reported to Raygun.

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  def test_error
    raise 'This is a test error'
  end
end

In the above code block, we have added a test_error method to the ApplicationController that raises an error. You can call this method in your application to generate a test error and ensure that it is reported to Raygun.

Overall, integrating Raygun into a Ruby on Rails project is a simple process that can help you quickly identify and diagnose issues in your application. By following the steps outlined above, you can start using Raygun to monitor your application and improve the overall user experience.

Raygun configuration options in Ruby on Rails

Here are the Raygun configuration options for Ruby on Rails integration along with their short explanations:

• api_key: Your Raygun API key.
• filter_parameters: An array of parameters that should be filtered out of error reports.
• enable_reporting: A boolean value that determines whether Raygun should report errors. Set to false in development mode to prevent spamming your Raygun account with test errors.
• async: A boolean value that determines whether Raygun should report errors asynchronously. Set to true to report errors in the background and avoid slowing down your application's response time.
• tags: An array of tags that should be included with error reports.
• custom_data: A hash of custom data that should be included with error reports.
• proxy_settings: A hash of proxy settings that should be used to connect to the Raygun API if your application is behind a firewall or proxy.
• ignore: An array of exceptions that should be ignored by Raygun. Use this to filter out errors that are not relevant to your application.
• before_send: A block of code that should be executed before error reports are sent to Raygun. Use this to modify error reports or add additional data.
• batch_size: The maximum number of errors that should be sent to Raygun in a single batch. Set to a lower value to reduce the size of each batch and avoid hitting rate limits.
• batch_time_interval: The maximum amount of time that should elapse before a batch of errors is sent to Raygun. Set to a lower value to ensure that errors are reported in a timely manner.

Conclusion
