Example 6 with Span

use of io.opencensus.trace.Span in project instrumentation-java by census-instrumentation.

the class HelloWorldServer method performWork.

// A helper function that performs some work in its own Span.
private static void performWork(Span parent) {
    SpanBuilder spanBuilder = tracer.spanBuilderWithExplicitParent("internal_work", parent).setRecordEvents(true);
    try (Scope scope = spanBuilder.startScopedSpan()) {
        Span span = tracer.getCurrentSpan();
        span.putAttribute("my_attribute", AttributeValue.stringAttributeValue("blue"));
        span.addAnnotation("Performing work.");
        // Working hard here.
        sleepFor(20);
        span.addAnnotation("Done work.");
    }
}
