Application Performance Monitoring
APM refers to the strategy and the practice of managing performance excellence, as measured by performance metrics and user experience monitoring. What application performance monitoring falls under is the more general term application performance management. While application performance monitoring only focuses on tracking the performance of an application, application performance management focuses on the broader concept of controlling an app’s performance levels — monitoring is a part of this.
The aim is to detect and pinpoint the issues in the application before the end user gets impacted.
