Application Performance Monitoring: A complete Overview
Application Performance Monitoring is a technique used to monitor key app performance metrics about the performance of a web application in production. It can be thought of as a ‘second wave’ of performance monitoring techniques, which was preceded by traditional host-based monitoring.
Host-based monitoring focused on indicators such as storage, memory, CPU, and network utilization. Application monitoring, which should focus on infrastructure monitoring, goes a step further and focuses on the actual “end-user” metrics of an application in real time.
There are many companies available that can provide reliable Web application performance monitoring tools. Application performance monitoring (APM) is the practice of tracking key software application performance metrics using monitoring software and telemetry data.
Application Performance Monitoring tools can function in several ways — common implementations include an agent process that is deployed alongside a web application that hooks into the application runtime to collect telemetry data from the process, or specialized web appliances that inspect Layer 7 traffic to generate telemetry.
In conjunction with the monitoring mechanism, traffic is typically generated by an external application and sent to the application in order to monitor performance at predefined throughput intervals.
The key difference between APM tools and other forms of monitoring is that the telemetry data is generated by inspecting the application runtime and the performance metrics that it exposes.
