Class ThreadContextScopeDecorator

  • All Implemented Interfaces:
    CurrentTraceContext.ScopeDecorator
    public final class ThreadContextScopeDecorator
extends CorrelationFieldScopeDecorator
    Adds ThreadContext properties "traceId", "parentId" and "spanId" when a span is current. These can be used in log correlation.

    Ex. 

    
 tracing = Tracing.newBuilder()
                  .currentTraceContext(ThreadLocalCurrentTraceContext.newBuilder()
                    .addScopeDecorator(ThreadContextScopeDecorator.create())
                    .build()
                  )
                  ...
                  .build();
