Feature Description
API Dimension Display
Click API Dimension Display at the top right of the page. The waterfall chart will simplify the displayed content. Only Spans with the calling role of Server or Consumer will be displayed. This display method measures application performance from the perspective of the server and consumer. When the calling relationship is complex, this display method can be used to quickly extract important information from the trace. When using the API dimension display, you can click the green ⊕ symbol in the API Name column to view all calls of the application in the pop-up dialog.
Full Trace Display
Click Full Trace Display at the top right of the page. The waterfall chart will display all Spans of the trace. Through the full trace display, you can get a comprehensive understanding of the details of each stage in the trace.
Viewing the Bird's Eye View
Click View Bird's Eye View at the top right of the page. A bird's eye view will be enabled at the top of the page. It reflects the call duration of key stages in the trace. When the calling relationship is complex, the bird's eye view can be used to quickly grasp the overall picture of the trace. When the bird's eye view is enabled, you can click Close Bird's Eye View at the top right of the page to disable it.
Span Details
Click any row in the waterfall chart to expand the Span details view. All information carried in a Span will be reflected in the Span details view. At the top of the tab, the most important Span information, including Span name, calling role, start time, end time, instance name, and peer service, is displayed. Depending on the different characteristics of Spans, the Span details view will also contain the following tabs:
Error: If the Span status is error, this tab will display specific error information.
Calling: If the Span represents an RPC or HTTP call, this tab will display specific calling information, which is carried by Span attributes with prefixes http and rpc.
SQL: If the Span represents an SQL call, this tab will display specific calling information, which is carried by Span attributes with the prefix db.
Event: If the Span contains events, this tab will display specific event information.
More Span Information: This tab will display all additional Span information, including all custom fields reported in the Span.
CLS Logs: If the application is associated with Cloud Log Service (CLS), this tab will query and display logs related to the call based on the Trace ID and Span ID. Ensure that the associated CLS topic has full-text index enabled.
If the Span contains a method stack snapshot, click Method Stack Snapshot in the Span details, and the execution time of each method in the local method stack will be displayed. For details, see Method Stack Snapshot.
