The official Splunk documentation for this page is Server trace information. For instructions on how to contribute to the docs, see CONTRIBUTING.md.
🚧 Status: Experimental
Setting SPLUNK_TRACE_RESPONSE_HEADER_ENABLED to true results in the
following headers being added to HTTP responses produced by the
instrumented application:
Access-Control-Expose-Headers: Server-Timing
Server-Timing: traceparent;desc="00-<serverTraceId>-<serverSpanId>-01"
The Server-Timing header contains the trace information (traceId and spanId)
in the traceparent format. This information is later consumed by the
splunk-otel-js-web library.
Also see the following documents for more information about Server-Timing header:
The following server frameworks and libraries add Server-Timing information:
| Framework/Library | Versions |
|---|---|
| Servlet API | 2.2-4.X (5.0+ is not supported yet) |
