What is apm?

In the field of information science and system control, APM is dedicated to monitoring and managing application software performance and availability. By monitoring and diagnosing performance problems of complex applications to ensure the good operation of software applications (expected services), APM has been commercialized.

APM = Application Performance Management, application performance management, real-time monitoring of enterprise systems to achieve systematic solutions for application performance management and fault management.

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

The coverage of APM includes five levels of implementation: end-user experience, application architecture mapping, application transaction analysis, in-depth application diagnosis, and data analysis.

The main functions of application performance management are as follows:

Monitor the performance of key enterprise applications: In the past, when enterprise IT departments measured system performance, they generally focused on providing end users with Utilization of the hardware components of the service, such as CPU utilization and number of bytes transferred over the network. While this approach also provides some valuable information, it ignores the most important factor - end-user response time. Now it is possible to truly measure user response time through transaction process monitoring and simulation. In addition, it is possible to report who is using an application, how often the application is used, and whether the user's transaction process was successfully completed.

Quickly locate application system performance faults: By monitoring various components of the application system (database, middleware), quickly locate system faults, such as Oracle database deadlocks and other issues.

Optimize system performance: Accurately analyze the system resource usage of each component of the system, the execution efficiency of middleware and database, and provide expert suggestions based on the application system performance requirements to ensure that the application uses the least system resources throughout its life cycle. Save TCO.

A key feature of the new application performance management environment is deployment where it is needed: close to services. There are multiple ways to accomplish this:
· In a hypervisor environment, monitoring the response time and resource consumption of virtual machines in the space;
· In a hypervisor environment without a hypervisor (such as a dedicated physical server) or managed When the program is out of reach (i.e. in an IaaS environment), it runs on the operating system;
·In a container;
·In a Java or .Net application server environment;
·On the end user device, continuously Or download instantly on demand.
