Examples with SpanContext io.opentracing.SpanContext used on opensource projects

Example 1 with SpanContext

use of io.opentracing.SpanContext in project jaeger-client-java by jaegertracing.

the class ServerFilter method filter.

@Override
public void filter(ContainerRequestContext containerRequestContext) throws IOException {
    // TODO: Add a @DisableTracing annotation and use the resourceInfo to check if it's applied
    try {
        Tracer.SpanBuilder builder = tracer.buildSpan(getOperationName(containerRequestContext)).withTag(Tags.SPAN_KIND.getKey(), Tags.SPAN_KIND_SERVER).withTag(Tags.PEER_HOSTNAME.getKey(), containerRequestContext.getUriInfo().getBaseUri().getHost()).withTag(Tags.HTTP_URL.getKey(), containerRequestContext.getUriInfo().getAbsolutePath().toString());
        // TODO(oibe) make X_UBER_SOURCE configurable for open source projects
        MultivaluedMap<String, String> headers = containerRequestContext.getHeaders();
        if (headers.containsKey(com.uber.jaeger.Constants.X_UBER_SOURCE)) {
            builder = builder.withTag(Tags.PEER_SERVICE.getKey(), headers.getFirst(com.uber.jaeger.Constants.X_UBER_SOURCE));
        }
        ServerRequestCarrier carrier = new ServerRequestCarrier(containerRequestContext);
        SpanContext spanContext = tracer.extract(Format.Builtin.HTTP_HEADERS, carrier);
        if (spanContext != null) {
            builder = builder.asChildOf(spanContext);
        }
        builder.startActive(true);
    } catch (Exception e) {
        log.error("Server Filter Request:", e);
    }
}
