Trace Details¶

In the Trace Explorer, click any trace to view its details, including relative time, duration, HTTP method, URL, status code, TraceId, Flame Graph, Span List, service call relationships, resource call relationships, and associated logs, hosts, metrics, and network information. For frontend applications (such as browsers), you can also view the request duration breakdown, including the time proportions of queueing, first byte, and download.

When you open trace details, the system displays the Waterfall Chart or Flame Graph first according to the Trace Details Default View setting in Preferences.

When opening a record from cross-workspace query results, the details and associated data are queried against the workspace where the record originated. When switching to the previous or next record, the originating workspace of the new record is used; a service with the same name or the same identifier cannot be used as a substitute for determining the source. If the originating workspace cannot be confirmed, the details entry is unavailable. Refresh and try again. For query scope and permission details, see Cross-Workspace Query.

Flame Graph¶

The Flame Graph clearly shows the flow and execution time of each span. On the right, you can view the service list and response times. Click a span to view its JSON content in the trace details, and use the mouse wheel to zoom in and inspect specific information.

For more details, see Using Flame Graphs to Analyze Trace Performance.

Span List¶

• Displays the resource name, count, duration, execution time, and execution time ratio of all spans in the trace.
• Enter a resource name or Span ID to search and match.
• Click any span to view its JSON content in the trace details, with the Flame Graph synchronized.
• If there are errors, error indicators are displayed.
• Click Error Spans to directly show the results that match the filter.

Waterfall Chart¶

View the parent-child relationships between resources.

The Waterfall Chart displays span data in the order of start time. The list on the left shows span data along with the execution time ratio of each resource. On the right, the waterfall chart is displayed chronologically.

• Enter the resource name or Span ID of a span to search and match;
• Collapse or expand the resources on the left with one click;

• Click to switch the execution time format;

• Click Error Spans to directly show the results that match the filter.

Service Call Relationships¶

Provides an overall view of the call relationships and call counts between different services, along with the execution time, average duration, and call count of each service.

Click any service node to view its details:

• Service operations and resources: lists the specific operations included in the service (such as API endpoints, methods, etc.) and related resources.

• Error status tracking:

  • If the service has errors, the error details are displayed directly.

  • Click to view the parent span of the service, allowing you to trace the upstream caller.

Uninstrumented HTTP External Services¶

When a trace passes through an HTTP external service without instrumentation, the system identifies the service based on upstream and downstream span information and generates a virtual Gateway node in the service call relationships.

The call relationship may appear as:

• When a unique caller can be identified: Caller Service → Gateway → Downstream Service;
• When a unique caller cannot be identified: Root → Gateway → Downstream Service.

The following conditions must be met simultaneously for a Gateway node to be generated:

• The downstream span is an HTTP Server Span;
• The parent_id of the Server Span is valid and not 0;
• The corresponding parent span is still not found after a supplementary query;
• The span contains a recognizable external service address.

A Gateway node is not generated when only an HTTP Client Span exists.

The virtual Gateway has no standalone span, so call count, duration, and error count are not calculated; related metrics are displayed as -, and the node is shown in a neutral state.

Resource Call Relationships¶

In the trace details, select a span and then switch to the Resource Call Relationships tab to the right of Service Call Relationships to view the upstream and downstream call relationships of the service and resource to which the span belongs.

The relationship diagram shows the aggregated call relationships of the resource within the selected time range; the scope is not limited to the current trace. Resources with the same name are distinguished by their owning service. When cross-workspace querying is enabled, only workspaces that the current account has permission to access are queried.

An independent time widget is provided in the upper-right corner of the diagram. Adjusting the time range updates only the resource call relationship diagram, without affecting the outer list or other detail tabs. Auto-refresh is disabled by default; manual refresh re-queries the currently selected interval.

After switching spans, the system updates the central resource and re-initializes the time range based on the start time of the new span. When switching tabs within the same span, the adjusted time range is retained.

The relationship diagram highlights the central resource node and provides node instance information, legend, zoom, fit-to-canvas, and fullscreen operations. When entering or exiting fullscreen, the current resource, time range, and query results are retained.

If a span lacks the necessary service or resource fields, the page shows the reason why the query cannot be performed. If no call relationship data is available, adjust the time range and try again. If the query fails, retry as prompted.

Quick Actions¶

Extended Attributes¶

• In the search bar, enter a field name or value to quickly search and locate.

• After selecting the field alias option, you can view the alias after the field name; choose as needed.

• On the trace details page, you can view the field attributes related to the current trace under Extended Attributes:

Error Details¶

On the trace details page, if the current trace contains errors, select the error span filter in the sidebar. The system automatically highlights all error spans. Click any highlighted span to view its associated error stack, logs, and other details.

For more details, see Error Tracking.

Service Context¶

You can quickly view the current service's runtime information, service dependencies, and integration information by retrieving the object category under the Infrastructure Resource Catalog and selecting the latest object based on create_time.
