After you install a probe for an application, Cloud Monitor 2.0 starts monitoring it. The Dependent services page shows details about the services your application depends on, including database calls, NoSQL calls, web calls, RPC calls, and message publishing.
Prerequisites
The application must be connected to Cloud Monitor 2.0.
Try the feature
Alibaba Cloud Playground provides a demo environment where you can experience the main features of Cloud Monitor 2.0.
Go to the Playground Demo. The workspace page is displayed by default.
In the navigation pane on the left, choose .

-
On the Application List page, click the name of the target application. In the top navigation bar, click Dependent services and select the service type that you want to view.
-
Use the quick filter section to filter the chart and service list by Request Type, Interface Name, and Instance.
-
The chart area shows time series curves for the total number of requests, errors, and average response time of dependent service requests over a specified time period.
-
The service list shows the request destination, type, and the three RED metrics (requests, errors, and average duration).
The service list supports the following operations:
-
Click an Interface Name to view the details of the corresponding service.

Interface details
-
Entity details: Shows the request count, error count, and average response time for the current interface, along with HTTP status code statistics and time series curves for slow calls. For more information, see Entity details.
-
Associated topology: Shows the upstream and downstream topology for the current interface. For more information, see Associated topology.
-
Access path (Web call): Shows time series charts for the request count, error count, and response time of the current interface.
