After you install the agent for an application, Cloud Monitor 2.0 begins monitoring it. On the Dependent Services page, you can view details about its dependencies, including database calls, NoSQL calls, web calls, RPC calls, and message publishing.
Prerequisite
The application is monitored by Cloud Monitor 2.0.
Try in Playground
Alibaba Cloud Playground provides a demo environment where you can experience the main features of Cloud Monitor 2.0.
Visit the Playground demo environment. By default, you are logged on to the

View in console
Log on to the Cloud Monitor 2.0 console, and select a workspace. In the left navigation pane, choose .
On the Applications page, click an application. Then, click Dependent Services and select a service type.
In the Quick Filter section, filter the charts and service list by request type, request target, and instance.
In the trend charts section, view the time series curves of the requests and errors, and average response time for a dependent service in a specified time range.
The service list displays information such as the name of the request target, request type, and RED (rate, errors, and duration) metrics.
In the service list, perform the following operations:
Click an operation to view service details.
Click Traces in the Actions column to view trace details.

Entity details: View the number of requests, number of errors, and average response time for the current API. This section also shows statistics for HTTP status codes and time series curves for slow calls.
Associated topology: View the upstream and downstream topology for the current API.
Access path (Web calls): View time series charts for the number of requests, number of errors, and response times for the current API.
SQL analysis: View a list of SQL requests initiated by the current API. You can filter the list by instance on the left side of the page to identify which SQL statement is slowing down a service.
NoSQL analysis: View a list of NoSQL requests initiated by the current API. You can filter the list by instance on the left side of the page to identify which NoSQL request is slowing down a service.
Sending statistics (Message publishing): View sending statistics for topics from the sender's perspective, including the number of requests, number of errors, and response time.
Exception analysis: View exceptions for the current API. You can optimize the code that causes the exceptions as needed.
Trace analysis: View detailed trace data for the current API. You can perform real-time analysis by combining filter conditions and aggregation dimensions to meet custom diagnostic needs for different scenarios.
