You can view the key performance metrics and topology of an application on the Application Overview page.
After the data of an application is reported to Tracing Analysis, Tracing Analysis starts to monitor the application in an all-around manner. On the Application Overview page, you can view the key performance metrics of the application. You can also view the topology to check the upstream and downstream services of your application and their dependencies.
Go to the Application Overview page

. At the top of the On the Application Overview page, you can view the key performance metrics and topology of the application.
View the key performance metrics of the application
- The total number of requests, average response time, number of errors, and number of spans in the specified time range, and the percentage changes between the statistics of the same day last week or last day and the current statistics.
- The line chart of how many times your application is called by upstream services and the response time, and how many times your application calls downstream services and the response time.
- The 10 spans that require the most time and their line charts of average response time.
View the topology of the application
On the Application Overview page, click the Topology Graph tab to obtain a better view of the upstream and downstream services of your application and the call relationships between the services and the application. Then, you can identify the performance bottlenecks of your application.
- The topology of service calls for the application in the specified time range.
- The numbers of calls on the client, calls on the server, and internal calls for the application, average response time, and error rate in the specified time range.
- The line charts of the number of requests, response time, and error rate in each minute of the specified time range.
Set the query time range
You can select a preset time range or enter a custom time range.
- Click the time option in the upper-right corner of the page, and then click a preset time range, such as Last 30 minutes,This week,Last 30 days.
