Application Software Performance Data Classification

Enterprise applications can be divided into the following types based on the system architecture:

Client/Server-Client/Server Architecture l Browser/web server layer 3 architecture l middleware application server layer 3 architecture l web server and middleware layer 3 Architecture

The above architecture consists of clients, Web servers, intermediate application servers, and database servers. Performance indicators and performance bottlenecks of the overall architecture can be analyzed through performance indicator monitoring at different levels.
