Application performance monitoring (APM) is the process of measuring and assessing the performance of software applications. It can be used to identify and diagnose issues, optimize performance, and improve the overall user experience. In order to measure application performance effectively, you need to understand how your applications work and how they interact with each other. You can also get more information about web application monitoring via https://germainux.com/software/germain-apm/apm-features.
There are a number of different metrics that you can use to measure application performance. The most important metric is response time, which measures how long it takes for an application to respond to a request from a user. You can also measure the amount of traffic that your application receives, the number of errors that it encounters, and the time it takes to load specific pages.
To get started with APM, you first need to set up a monitoring system. This system should include a server that collects data from your applications, a database that stores the data, and a reporting tool that lets you analyze the data. You can also use APM software to monitor your applications. Chapter 8, “Performance Monitoring Tools” shows you how to install and configure JProfiler and the Java Server Pages (JSP) developer tools.
APM doesn’t replace a performance testing tool like JMeter. It can give you some insight into what’s happening with your web applications, but it cannot be used alone to test your web applications. The information that APM provides is complementary to that of other tools.
