Application performance management (APM), alternatively referred to as application performance monitoring, is the IT management discipline that ensures the optimal performance of applications from a business and end-user standpoint.
Comprehensive APM solutions measure and monitor performance, provide early warning for potential problems, and help to troubleshoot issues before they impact the business or end-user experience.
Current trends in the APM market are moving away from narrowly focused systems and network management solutions and toward more comprehensive solutions that provide visibility across all tiers of the application infrastructure, including web servers, application servers, network, database, and storage.
ExtraHop Networks advocates a network-based approach to APM.
