What is APM tool used for?

Scout is Ruby, Python and Laravel Application Performance Monitoring (APM) that pinpoints and prioritizes performance and stability issues like N+1 database queries and memory bloat and leaks in Ruby and Python applications. Scout's tracing logic detects and highlights the exact line of code causing the performance abnormality, and with detailed backtraces, you can fix the issue before customers are impacted. Scout provides further insights by automatically calculating memory increase, tracking object allocations to minimize overhead, and prioritizing query data by potential time saved.
