Checking the Fault Propagation Chain on AOM

AOM provides the propagation chain of abnormal calls based on key metrics (such as the trace, average RT, and error rate), and displays key metric data of services and their associated services, helping you locate root causes more effectively.

Procedure

Log in to the AOM 2.0 console.
In the navigation pane, choose Application Monitoring > Intelligent Insights (Beta).
Set a time range in the upper right corner of the page. You can use a predefined time label, such as Last hour and Last 6 hours, or customize a time range.
Select a target application from the drop-down list above the filter.
Click an event card or list to go to the event details page and check the fault propagation chain.

The fault propagation chain displays the faults in traces. You can locate root causes based on this chain. The fault propagation chain function is supported for the following types of abnormal events:
- Service Avg. RT Sharply Increases
- Top N API Avg. RT Sharply Increases
- Service Error Rate Sharply Increases
- Top N API Error Rate Sharply Increases
