Calculate the breakdown of execution time and adjust the color scheme by either service or host.
To get a closer look at the flame graph, zoom in by scrolling:
The List view aggregates resources by service and sorts them according to their corresponding count of spans. Services are sorted per relative percentage of execution time spent by the trace in each service:
Click on a span in the flame graph to show its metadata below the graph. If there’s an error, the stack trace is provided:
If you are analyzing a trace reporting an error, the error has a specific display if you follow the special meaning tags rules. When submitting your traces you can add attributes to the
Some attributes have special meanings that lead to a dedicated display or specific behavior in Datadog:
|Allows specific SQL query formatting and display in Datadog’s UI.|
|Allows dedicated display for error message.|
|Allows dedicated display for error types. Available types include, for instance, in Python |
|Allows a better display of the stack trace of an exception in Datadog’s UI (red boxes, etc…)|
View the host information related to the trace including host tags and graphs around the time of the trace.
See logs related to your service at the time of the trace. When you hover over a log, a line showing its timestamp is displayed on the trace flame graph. Clicking on the log brings you to the log explorer search.
Click on a service’s span to see the processes running on its underlying infrastructure. A service’s span processes are correlated with the hosts or pods on which the service runs at the time of the request. You can analyze process metrics such as CPU and RSS memory alongside code-level errors to distinguish between application-specific and wider infrastructure issues. Clicking on a process will bring you to the Live Processes page. To view span-specific processes, enable process collection. Related processes are not currently supported for serverless and browser traces.
