URL Tracing¶
You can view the topology of a single call, as well as the overall topology between different services. In some scenarios, the call relationships of an important business need to be traced. This process is called URL tracing. For example, to trace the API for creating online shopping orders. In APM, URL tracing consumes a large number of resources. Therefore, an entry URL will not be added for tracing by default. However, you can set that if necessary. APM has a limit on the total number of URLs added for tracing. It focuses on tracing the downstream calls for the APIs that are added for tracing. Through URL tracing, you can monitor the call relationships between important APIs and downstream services, and then detect problems more precisely.
Configuring URL Tracing¶
Log in to the management console.
Click
on the left and choose Application > Application Performance Management.In the navigation pane, choose Application Monitoring > Metrics.
