- 依次点击左栏
应用监控、顶栏调用链分析； - 将故障时段
2025-08-28 15:08:03 ~ 2025-08-28 15:13:03原样复制，粘贴至页面右上角时间输入框，回车确认； - 在页面左侧
快捷筛选栏，选定错误状态，可得故障时段内全部错误调用； - 进入
Trace列表，在操作列点击详情按钮，可查看 Trace 信息：
观察拓扑视图
在顶栏点选拓扑视图，可见服务之间调用关系。视图大小可通过鼠标滚轮缩放；各方块位置可自由拖动,检查多组调用链，发现共同点系payment服务故障：
智能分析
在Trace详情页面，点击检测到异常右侧的魔棒按钮，可展开 Copilot 并向其提问：
交叉检验
在 多个Trace详情页面，通过Copilot分析，检测到相同的异常
得出结论
结合拓扑视图、Copilot 分析、日志校验，可定位根因系payment服务出现故障：
{"problem_id": "001", "root_causes": ["payment.Failure"]}
