Tracing configuration used by org.llm4s.trace.Tracing.
mode selects the backend. Core builds NoOp and Console itself; Console reads captureContent from extras (the llm4s.tracing.console block, false by default, so the console prints no prompt or completion text unless enabled). Every other mode is served by a org.llm4s.trace.spi.TracingBackend on the classpath, which reads its own keys from extras: the block llm4s.tracing.<mode> for the selected mode, flattened to strings. The backend's module ships that block's defaults and ${?VAR} bindings in its own reference.conf - the arrangement provider descriptors have with NamedProviderConfig.extras. So llm4s-observability reads llm4s.tracing.langfuse (LangfuseConfig.fromExtras) and llm4s-observability-otel reads llm4s.tracing.opentelemetry.
Until slice 6 (#1133) this class also carried typed langfuse and openTelemetry fields; they left core with their backends.
toString redacts the extras values, which may be credentials.
Value parameters
- extras
-
every value under
llm4s.tracing.<mode>for the selected mode, as a string, keyed by its path within that block (publicKey,headers.Authorization); a list or object value is rendered as HOCON. Empty when the block is absent. Build one with TracingSettings.apply and change it with thewith*setters; the constructor andcopyare private, so a new field never breaks callers. - mode
-
selects the tracing backend:
Console,NoOp, orNamedfor a backend outside core (Named("langfuse"),Named("opentelemetry"), ...)
