Application performance layer observability focuses on monitoring specific applications built on the CCSE, including Metrics, Tracing, and Logging. For example, monitoring the thread count metrics of a Java application built on container services.

Solutions	Solution Description	Application Scenario
Non-Intrusive Application Performance Monitoring (APM) Solution	eSurfing Cloud Application Realtime Monitoring Service (ARMS) is recommended as the application performance layer monitoring solution. ARMS is an Application Performance Management (APM) monitoring product of eSurfing Cloud. By installing the cubems plug-in in the CCSE cluster and marking Java applications deployed, you can achieve comprehensive monitoring of Java applications using ARMS without modifying any code. This allows for quickly locating faulty and slow interfaces, reproducing parameter calling, detecting memory leaks, discovering system bottlenecks, and more efficiently diagnosing problems online.	This approach is applicable to specific scenarios, including application monitoring for JAVA applications. The integration of the solution supports a non-invasive approach, with no need for code modification.
