Application overview

Background information

SAE is integrated with the Application Monitoring sub-service of Application Real-Time Monitoring Service (ARMS) to monitor Java applications. ARMS is an application performance management (APM) service. To monitor an application, you need to only install the ARMS agent. You do not need to modify the code of the application. The ARMS agent helps you identify abnormal or slow API operations, view request parameters, and detect system bottlenecks. This improves the efficiency of online troubleshooting. For more information, see What is Application Monitoring?

Entry point

1. Log on to the SAE console.

2. In the left-side navigation pane, click Applications. In the top navigation bar, select a region. Then, click the name of an application.

3. In the left-side navigation pane, choose Application Monitoring > Application Overview. On the Application Overview page, view the required information on the Overview tab.

Metric categories

The Overview tab displays the following metrics:

• The total number of requests, average response time, number of instances, number of full garbage collection (GC) events, and number of slow SQL queries within a specific time range, and day-on-day or week-on-week changes.

• Application Events: application events, such as availability alerts, application monitoring alerts, and Kubernetes cluster events. Availability alerts may be triggered due to deadlocks, out-of-memory (OOM) errors, or application startup. Move the pointer over a column chart to view the event list at a specific point in time. For more information, see Event center.

• Application Support Services: time series curves for the number of requests to the services that are provided by the application and average response time.

• Application Dependent Services: time series curves for the number of requests to the dependent services, average response time, number of instances within the application, and HTTP status codes.
