When connected to Application Real-Time Monitoring Service (ARMS), your application is monitored by ARMS in all rounds. You can view the key health metrics of your application on the Application Overview page. The topology allows you to preview the upstream and downstream dependent components of the component, and the 3D topology allows you to view the health status of your application, services, and hosts.


  1. Log on to the ARMS console. In the left-side navigation pane, choose Application Monitoring > Applications.
  2. On the Applications page, click the name of the target application to access the Application Overview.

    At the top of the Application Overview page, you can click tabs Overview Analysis, Topology Graph, and 3D Topo (Probation) to view the corresponding information.


  • Key application metrics
    The Overview Analysis tab shows these key metrics:
    • Total number of requests, average response time, error count, real-time number of instances, number of full garbage collection (GC) activities, number of slow SQLs, number of exceptions within the specified time range, and how they change compared with the previous day and previous week.

    • Application Support Services: time sequence curves of the application support service requests and average response time.

    • Application Dependent Services: time sequence curves of the application dependent service requests, average response time, and number of application instances, and statistics of the HTTP status code.

    • System info: time sequence curves of CPU, memory, and load.

    • Slow call: time sequence curves and details of slow calls.

    • Statistical analysis: analysis on slow API calls and exception types.

  • Application topology

    On the Topology Graph tab, you can get a better view of the upstream and downstream components of your application and their call relations, allowing you to effectively identify the bottlenecks of your application.

  • 3D Topo (Probation)

    The 3D Topo (Probation) tab provides a comprehensive view of the health conditions for your application, service, and host, and the upstream and downstream dependencies of the application. With the 3D topology, you can quickly identify the services that caused failures, applications influenced by the failures, and associated hosts. This enables you to thoroughly investigate the root cause of the failures, and then fix the issues quickly. For more information about the 3D topology function, see 3D topology.
