Prerequisites

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

• A basic understanding of Ruby on Rails development
• A working Ruby on Rails application
• An AppDynamics account
• The AppDynamics Ruby agent installed in your application
• Basic knowledge of the AppDynamics Controller and its features
• Familiarity with the AppDynamics Dashboard and how to navigate it
• Access to the AppDynamics Analytics feature (optional)
• A web browser (Chrome, Firefox, or Safari recommended)

Ruby on Rails AppDynamics step by step setup and configuration

Integrating AppDynamics into a Ruby on Rails project is a straightforward process. The first step is to install the AppDynamics Ruby agent in your application. You can do this by adding the following line to your Gemfile:

gem 'appdynamics_ruby_agent'

Once you have added the gem to your Gemfile, run the following command to install it:

bundle install

Next, you will need to configure the AppDynamics agent. This can be done by creating a new initializer file in the config/initializers directory. In this file, you can set various configuration options, such as the name of your application and the location of the AppDynamics Controller. Here is an example configuration:

require 'appdynamics_ruby_agent'

AppdynamicsRubyAgent.configure do |config|
  config.controller_host = 'your-controller-host'
  config.controller_port = 8090
  config.application_name = 'your-application-name'
  config.tier_name = 'your-tier-name'
  config.node_name = 'your-node-name'
end

In this example, we have set the host and port of the AppDynamics Controller, as well as the name of our application, tier, and node.

Finally, you will need to start the AppDynamics agent. This can be done by adding the following line to your application's entry point (e.g., config.ru or bin/rails):

require 'appdynamics_ruby_agent'
AppdynamicsRubyAgent.start

With these steps completed, your Ruby on Rails application is now integrated with AppDynamics, and you can start monitoring its performance.

AppDynamics configuration options in Ruby on Rails

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

• controller_host: The hostname or IP address of the AppDynamics Controller.
• controller_port: The port number of the AppDynamics Controller.
• application_name: The name of your Ruby on Rails application in AppDynamics.
• tier_name: The name of the tier in AppDynamics that your Ruby on Rails application belongs to.
• node_name: The name of the node in AppDynamics that your Ruby on Rails application is running on.
• account_name: The name of your AppDynamics account.
• account_access_key: The access key for your AppDynamics account.
• ssl_enabled: Whether to use SSL when communicating with the AppDynamics Controller.
• ssl_ca_cert_path: The path to the SSL CA certificate file.
• ssl_cert_path: The path to the SSL client certificate file.
• ssl_key_path: The path to the SSL client key file.
• debug: Whether to enable debug logging for the AppDynamics agent.

These configuration options allow you to customize the behavior of the AppDynamics agent in your Ruby on Rails application. You can set the name of your application, tier, and node, as well as the hostname and port of the AppDynamics Controller. You can also enable SSL and debug logging, and provide authentication credentials for your AppDynamics account. By configuring these options, you can ensure that the AppDynamics agent is working correctly and providing accurate performance metrics for your Ruby on Rails application.
