An upstream application of a specific application is an application that sends data to the specific application. This topic shows you how to view the information about upstream applications, including the response time, number of requests, and number of errors.

Limits

Enterprise Distributed Application Service (EDAS) allows you to view the information about upstream applications in Professional Edition and Platinum Edition, but not in Standard Edition.

Go to the feature page

  1. Log on to the EDAS console.
  2. Go to the Application Overview page by using one of the following methods:
    • In the left-side navigation pane, choose Resource Management > Container Service Kubernetes Clusters or Resource Management > Serverless Kubernetes Clusters. 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.
  3. In the left-side navigation pane of the application details page, choose Monitor > Instance Details.
  4. In the left-side pane of the Instance Details page, select the instance that you want to view and click the Upstream application tab on the right side of the page.

Response time

In the Response Time section, a time series curve indicates the response time (RT) of the upstream applications of the application in the specified time period.

In the Response Time section, perform the following operations as needed:
  • Move the cursor over the statistics chart to view the statistics.
  • Select a period of time to view the statistics for the specified period.

Number of requests

In the Requests section, a time series curve indicates the number of requests of the upstream applications of the application in the specified time period.

In the Requests section, perform the following operations as needed:
  • Move the cursor over the statistics chart to view the statistics.
  • Select a period of time to view the statistics for the specified period.

Number of errors

In the Errors section, a time series curve indicates the number of errors of the upstream applications of the application in the specified time period.

In the Errors section, perform the following operations as needed:
  • Move the cursor over the statistics chart to view the statistics.
  • Select a period of time to view the statistics for the specified period.
