Scout’s Performance Monitoring (APM) tool pinpoints and prioritizes performance and stability issues in Ruby, such as N+1 database queries and memory bloat. With Scout’s tracing logic, developers can detect the exact line of code causing the performance abnormality, and with detailed backtraces, you can debug the issue before customers ever notice. Scout’s Ruby monitoring tool provides actionable insights by automatically calculating memory increase, prioritizing query data by potential time saved, and tracking object allocations to minimize overhead.

Scout’s database query monitoring feature helps you identify slow and repeatedly expensive database queries within your Ruby application. The database feature specifically collects metrics around the database and concisely visualizes only the relevant insights you need to understand how your database performs in relation to your app. Connect transaction traces to their corresponding calls to provide better insights into what the query is and where it occurred with the database monitoring feature.
