How to use APM to optimize the performance of PHP applications?

What exactly is APM?

This is the first time for many people to hear the concept of APM. This article mainly explains how to use APM solutions to optimize PHP application performance. First, let’s introduce APM (Application Performance Management), which is application performance management. It monitors enterprise systems in real time to achieve systematic solutions for application performance management and fault management.

Application performance management is a relatively new network management direction. It mainly refers to monitoring and optimizing key business applications of enterprises, improving the reliability and quality of enterprise applications, ensuring that users receive good services, and reducing the total cost of IT (Total Cost). of Ownership, referred to as TCO). The strong performance of an enterprise's key business applications can improve competitiveness and achieve commercial success. Therefore, strengthening application performance management (APM) can bring huge business benefits.

Overview of global performance

The application performance overview on the application homepage allows you to quickly perceive the health and overall performance status and problems of the application. Using the overview as the entrance, you can easily trace performance measurement points such as geographic information, key transactions, error statistics, etc. to complete application performance management. In the application performance overview, the following information is included: response time, performance index, throughput (unit: rpm requests per minute), key transactions, error rate, recent events, server information
