Prerequisites

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

• A basic understanding of Ruby on Rails and web application development
• A SignalFx account and access to the SignalFx web interface
• A Ruby on Rails application that you want to monitor
• A Linux or macOS development environment
• Basic knowledge of the command line and terminal
• Ruby and RubyGems installed on your development environment
• Bundler installed on your development environment
• The ability to install software and dependencies on your development environment
• A text editor or integrated development environment (IDE) for editing code

By ensuring that you have these prerequisites in place, you will be able to follow along with the tutorial and successfully monitor your Ruby on Rails application using SignalFx.

Ruby on Rails SignalFx step by step setup and configuration

Integrating SignalFx into a Ruby on Rails project is a straightforward process that involves installing the SignalFx agent and configuring it to collect metrics from your application. To get started, you will need to install the SignalFx agent on your development environment and configure it to collect metrics from your application.

First, you will need to install the SignalFx agent by running the following command in your terminal:

curl -sSL https://dl.signalfx.com/signalfx-agent.sh | bash

Next, you will need to configure the agent to collect metrics from your Ruby on Rails application. To do this, you will need to add the following code to your config/application.rb file:

require 'signalfx'

config.middleware.use SignalFx::Rack::InstrumentationMiddleware, client: SignalFx.new

This code adds the SignalFx middleware to your application's middleware stack, which allows the agent to collect metrics from your application.

Once you have added the middleware, you can start sending custom metrics to SignalFx by using the SignalFx client object. For example, to send a custom metric that tracks the number of requests to your application, you can add the following code to your controller:

SignalFx.client.increment('requests.count')

This code increments the requests.count metric every time a request is made to your application.

Finally, you can create custom dashboards in the SignalFx web interface to monitor your application's performance. To do this, you will need to log in to the SignalFx web interface and create a new dashboard. You can then add charts that display metrics collected from your application, such as the number of requests, response time, and error rate.

Overall, integrating SignalFx into a Ruby on Rails project is a simple process that can provide valuable insights into your application's performance. By following these steps, you can start monitoring your application in real-time and optimizing its performance to provide the best possible user experience.

SignalFx configuration options in Ruby on Rails

When integrating SignalFx with a Ruby on Rails application, there are several configuration options available. These options allow you to customize the behavior of the SignalFx agent and collect metrics that are relevant to your application. The following is a list of SignalFx configuration options for Ruby on Rails integration:

• access_token: The access token used to authenticate with the SignalFx API.
• environment: The environment in which your application is running (e.g., production, staging, development).
• hostname: The hostname of the machine running the SignalFx agent.
• realm: The realm in which your SignalFx account is located.
• reporting_delay: The delay between metric reporting intervals.
• timeout: The timeout for requests to the SignalFx API.
• trace_enabled: Whether or not to enable tracing for your application.
• trace_sampling_rate: The sampling rate for tracing.
• trace_span_name_limit: The maximum length of a trace span name.
• trace_span_tag_limit: The maximum number of tags that can be attached to a trace span.

By configuring these options, you can fine-tune the behavior of the SignalFx agent and collect metrics that are relevant to your application. This can help you to identify performance issues and optimize your application for the best possible user experience.
