On the Application Overview page of an application, you can view the information about the related Kubernetes cluster, such as the region, microservice namespace, and status of the cluster, and the application diagnosis report. You can also view key metrics for the health status of the application. The metrics include overall metrics, such as the total number of requests and average response time, metrics of provided services and dependent services, and system metrics, such as CPU utilization and memory usage.
Go to the Application Overview page
- Log on to the EDAS console.
- Go to the Application Overview page by using one of the following methods:
- In the left-side navigation pane, choose or . In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace. On the Container Service Kubernetes Clusters or Serverless Kubernetes Clusters page, click a cluster ID. In the Applications section of the Cluster Details page, click the name of the application that you want to manage.
- In the left-side navigation pane, click Applications. In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace. Select Container Service or Serverless Kubernetes Cluster from the Cluster Type drop-down list and click the name of the application that you want to manage.
View the overall information about the application
On the Application Overview page, you can view the overview information about the application, such as the details of the related Kubernetes cluster. The cluster details include the name, region, type, status, creation time, and specifications of the cluster, and the application diagnosis report. In addition, you can view the Server Load Balancer (SLB) instance of the cluster.

View the application diagnosis report
If an exception occurs on an application, move the pointer over the diagnosis report
icon 
next to the application name on the Application Overview page. Then, the exception message for the application appears. You can click Diagnosis Report to view the complete diagnosis report.
View the overall analysis
The Overall Analysis tab displays the following key metrics:
- The total number of requests, average response time, number of errors, number of full heap GCs (Full GCs), number of slow SQL queries, number of exceptions, and number of slow calls in the specified time period. You can also check how the values of these metrics change compared with the values of the corresponding metrics in the previous week or on the previous day.
- Application Support Services: time series curves for the number of requests to the
provided services and average response time.
If you use EDAS Professional Edition or Platinum Edition, you can click a spike in the curves to perform in-depth analysis.
- 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.
- System Info: time series curves for CPU utilization, memory usage, and load.
- Thread Profiling: time series curves and details of slow calls.
- Statistical Analysis: analysis on slow API calls and exception types.
View the application topology
On the Topology Graph tab, you can view the upstream and downstream components of your application and the call relationship between the components and the application in the topology. The topology helps you identify the bottlenecks of your application.
