Locating Problems Based on Topologies

Background

In scenarios where external requests increase sharply or the load changes abruptly, application performance problems may occur. For example, external requests are responded slowly or some requests are abnormal. Quickly identifying, locating, and handling application performance problems become urgent needs.

APM is a cloud application diagnosis service and has powerful analysis tools. It displays the application status, call processes, and user operations through topologies, tracing, and transaction analysis, so you can quickly locate and resolve faults and performance bottlenecks.

For example, you can view the call relationships between services and quickly locate abnormal instances through topologies. You can also drill down to service resources to find out the faulty method tracing and determine root causes.

Application Scenarios

Routine inspection of application metrics such as latency, throughput, and number of errors
Quick locating of error calls

Procedure

Log in to the APM console. In the navigation pane, choose Topology.
On the Topology page, view metrics, service relationships, and top statistics.
Right-click the abnormal tracing and choose Find Call-Chain from the shortcut menu.
On the Tracing page, view the error or high-latency tracing, and click View Call Relationship in the Operation column.
On the Call Relationship page, obtain the error call information and determine the root cause. For example, click View Details to obtain the error call information.
