The APM paradox: Too much data, too few answers

Published: 2025-11-03 | Origin: /r/programming

Application Performance Monitoring (APM) serves as a tool for developers to diagnose application slowness and enhance user experience. Traditionally, it involves collecting extensive data displayed through dashboards and request traces, targeting known issues like N+1 queries and slow third-party API calls. However, traditional APMs are often built to address previously identified problems, which can leave developers unprepared for unforeseen issues that modern applications encounter. These legacy solutions can overwhelm with data yet fail to provide insights during production failures, leading
