      This document describes how to view application details, such as the topology, number of requests, response time, number of errors, and throughput.

      Application Details

      1. Go to the Application details page in the APM console.
      2. On the Application details page, you can view the total number of requests, average response time, average error rate, slow call, slow SQL, number of exceptions, and full GC of the service in the current time range.
      
      

      Performance monitoring

      This module displays the trend of the average response time, average throughput, average error rate, and Apdex of the application on the selected server or client within the specified time range. You can click the clock icon in the top-right corner of each chart to compare the data of any day in the last 30 days with the current data.

      Call analysis

      This module displays the upstream and downstream local topology centered on the current service. Hover over the target node to view the average throughput, response time, and error rate of the corresponding application. APM uses topology icons in different colors for identification. Green indicates that the application is healthy, orange delayed, and red abnormal.

      JVM monitoring

      This module displays the trend of critical JVM metrics, including average/maximum garbage collection (GC) count, CPU utilization, heap space, NoHeap space, heap space refinement, and number of JVM threads.
