After data is reported to Tracing Analysis, the components of Tracing Analysis perform aggregate computing on the data in real time. Generally, the result is available with a specific latency. If you want to view the real-time diagnostics result during troubleshooting, you can use the real-time diagnostics feature.
Background information
When you use the real-time diagnostics feature, a temporary storage mechanism is enabled. After data is reported, the diagnostics result is displayed without the need of real-time statistics.
The real-time diagnostics feature does not affect normal statistics. This feature is automatically disabled after five minutes. After the feature is disabled, you can enable the feature again.
By default, the real-time diagnostics page is refreshed at intervals of 10 seconds. You can also disable the scheduled refresh feature.

The list of traces
View the waterfall chart of a trace
The Traces tab displays the span name, timeline chart, application name, start time, server IP address, and status of each trace.
The IP Address column may display IP addresses or server names. The information displayed depends on the display settings that are configured on the Application Settings page. For more information, see Manage applications and tags.
On the Traces tab, click the ID of the trace. On the Traces page, view the waterfall chart of the trace.
Optional: On the Traces tab, perform the following operations:
Move the pointer over the name of a span to view the information about the span, including the duration, start time, tags, and log events.
