Ruby on Rails Rookout step by step setup and configuration

Integrating Rookout into a Ruby on Rails project is a straightforward process that involves installing the Rookout SDK and adding a few lines of code to your application. Here are the steps required to integrate Rookout into your Ruby on Rails project:

1. Install the Rookout SDK: The first step is to install the Rookout SDK in your development environment. You can do this by adding the following line to your Gemfile:

gem 'rookout'

Then, run the following command to install the gem:

bundle install

2. Configure Rookout: Once you have installed the Rookout SDK, you need to configure it with your Rookout account details. You can do this by adding the following lines of code to your config/application.rb file:

require 'rookout'
Rookout.start

This will start the Rookout SDK and connect it to your Rookout account.

3. Add Rookout breakpoints: Once you have configured Rookout, you can add breakpoints to your code using the Rookout web interface. To do this, navigate to the Rookout web interface and select your Ruby on Rails application. Then, click on the "Add Breakpoint" button and enter the details of the breakpoint you want to add.

4. Test your application: With Rookout configured and breakpoints added, you can now test your Ruby on Rails application. When your application hits a breakpoint, Rookout will capture the relevant data and display it in the Rookout web interface.

Overall, integrating Rookout into a Ruby on Rails project is a simple process that can be completed in just a few steps. By adding Rookout to your development workflow, you can quickly and easily debug your applications in real-time, improving the quality and reliability of your code.

Rookout configuration options in Ruby on Rails

Here are the Rookout configuration options for Ruby on Rails integration:

• ROOKOUT_TOKEN: This is the Rookout token for your account. It is required to connect your application to the Rookout web interface.
• ROOKOUT_ROOK_TAGS: This is a list of tags to apply to all Rookout events. Tags can be used to filter and group events in the Rookout web interface.
• ROOKOUT_ROOK_URL: This is the URL of the Rookout web interface. By default, it is set to https://app.rookout.com.
• ROOKOUT_ROOK_SSL_VERIFY: This option controls whether SSL verification is enabled for the Rookout connection. By default, it is set to true.
• ROOKOUT_ROOK_CA_CERTS: This option allows you to specify a custom CA certificate file for SSL verification.
• ROOKOUT_ROOK_LOG_LEVEL: This option controls the logging level for the Rookout SDK. By default, it is set to info.
• ROOKOUT_ROOK_LOG_FILE: This option allows you to specify a custom log file for the Rookout SDK.

These configuration options can be set in your Ruby on Rails application's config/application.rb file or in an environment-specific configuration file such as config/environments/production.rb. By configuring these options, you can customize the behavior of the Rookout SDK to meet your specific needs.
