Ruby On Rails Monitoring

Easily monitor the performance of your Ruby on Rails application with the scout Ruby gem. Scout automatically monitors the performance of your controller-actions, records transaction traces, and instruments many Ruby libraries like ActiveRecord, Net::HTTP, Redis, and more.

Scout provides extra monitoring magic on top of our default monitoring for Ruby apps when you use Ruby on Rails:

Key Ruby on Rails Monitoring Features

Instrument your custom code with Autoinstruments

Manually adding vendor-specific instrumentation to your custom code is a tedious process. When you enable Autoinstruments, Scout automatically instruments code expressions within your app to narrow down the cause of slowness in the code you and your dev team creates.

Monitors web+background jobs

Scout both the performance of requests to your controller-actions and background jobs (Sidekiq, Delayed Job, Resque, and Sneakers are supported).

Identify capacity problems with queue time

Scout automatically measures the time in queue for your Rails apps, indicating if requests are stacking up in a queue.

Database analysis

Do you know all of the queries your app is making to your database? With Scout, you do. Broken down and sortable by % Time Consumed, Throughput, Mean and 95% Query Time. Select a time period on our charts and we’ll show you which queries increased or decreased during that time compared to the overall duration.

Rails and Ruby Version Support

Our Ruby agent supports Ruby on Rails 2.2+ and Ruby 1.8.7+.

Installation Guide

There are just three steps to start using Scout:
