This guide walks you through setting up Application Performance Monitoring (APM) on a Ruby application. These instructions can also be found on the Installation page in your Middleware Account. View example code here.

​

Prerequisites

ruby --version

​

Install

​

Step 1: Add Gems to Your Gemfile

• Linux Gemfile
• Windows Gemfile

   gem 'opentelemetry-sdk'
   gem 'opentelemetry-exporter-otlp'
   gem 'opentelemetry-instrumentation-all'
   gem 'pyroscope'
   gem 'middleware_apm_linux', '~> 2.1.0'

​

Step 2: Import Tracker

• Linux Environment
• Windows Environment

    require 'middleware/ruby_gem_linux'
    Middleware::RubyGem.init

​

Step 3: Capture Application Data

​

Traces

OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:9320 \ 
OTEL_SERVICE_NAME="<Your Service Name>" \ 
OTEL_RESOURCE_ATTRIBUTES=project.name="<Your Project Name>" \ 
MW_API_KEY=<Your API Key> \ 
<YOUR COMMAND> 

​

Profiling

Application Profiling is auto-configured upon completion of Step 2.

​

Continuous Profiling

Continuous profiling captures real-time performance insights from your application to enable rapid identification of resource allocation, bottlenecks, and more. Navigate to the Continuous Profiling section to learn more about using Continuous Profiling with the Ruby APM.
