Prerequisites

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

• A Ruby on Rails application that you want to monitor
• A Scalyr account
• Scalyr agent installed on the server where your Ruby on Rails application is running
• Basic knowledge of Ruby on Rails and Linux command line
• Access to the terminal or command line interface on your local machine and the server where your application is running
• Basic understanding of logging and monitoring concepts
• Familiarity with the Scalyr user interface and basic navigation

Ruby on Rails Scalyr step by step setup and configuration

Integrating Scalyr into a Ruby on Rails project is a straightforward process that can be completed in just a few steps. The first step is to install the Scalyr agent on the server where your Ruby on Rails application is running. This can be done by following the instructions provided by Scalyr. Once the agent is installed, you can configure it to monitor your application's logs and metrics.

To configure Scalyr to monitor your Ruby on Rails application, you will need to add the Scalyr Ruby gem to your project's Gemfile. You can do this by adding the following line to your Gemfile:

gem 'scalyr'

Next, you will need to configure the Scalyr gem to send logs and metrics to your Scalyr account. You can do this by adding the following code to your config/application.rb file:

config.logger = Scalyr::Logger.new(
  api_key: 'YOUR_API_KEY',
  app_name: 'YOUR_APP_NAME',
  server_attributes: { environment: Rails.env }
)

Scalyr.metrics(
  api_key: 'YOUR_API_KEY',
  app_name: 'YOUR_APP_NAME',
  server_attributes: { environment: Rails.env }
)

Replace YOUR_API_KEY with your Scalyr API key and YOUR_APP_NAME with the name of your Ruby on Rails application. This code will configure the Scalyr logger to send logs to your Scalyr account and the Scalyr metrics module to send metrics data.

Finally, you can test your Scalyr integration by generating some log messages and metrics data. You can do this by adding the following code to your controller or model:

logger.info('Hello, Scalyr!')
Scalyr.counter('page_views', 1)

This code will generate a log message and increment a counter metric in your Scalyr account. You can then navigate to your Scalyr dashboard to view the logs and metrics data.

In summary, integrating Scalyr into a Ruby on Rails project involves installing the Scalyr agent, adding the Scalyr gem to your project, configuring the Scalyr logger and metrics module, and testing your integration by generating log messages and metrics data. With these steps completed, you can monitor your Ruby on Rails application with Scalyr and gain valuable insights into its performance.
