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

Example 1 with Span

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

the class SpanCreationRequestInterceptor method process.

@Override
public void process(HttpRequest httpRequest, HttpContext httpContext) throws HttpException, IOException {
    try {
        Span currentActiveSpan = tracer.activeSpan();
        Tracer.SpanBuilder clientSpanBuilder = tracer.buildSpan(getOperationName(httpRequest));
        if (currentActiveSpan != null) {
            clientSpanBuilder.asChildOf(currentActiveSpan);
        }
        Span clientSpan = clientSpanBuilder.start();
        RequestLine requestLine = httpRequest.getRequestLine();
        Tags.SPAN_KIND.set(clientSpan, Tags.SPAN_KIND_CLIENT);
        Tags.HTTP_URL.set(clientSpan, requestLine.getUri());
        if (httpContext instanceof HttpClientContext) {
            HttpHost host = ((HttpClientContext) httpContext).getTargetHost();
            Tags.PEER_HOSTNAME.set(clientSpan, host.getHostName());
            Tags.PEER_PORT.set(clientSpan, host.getPort());
        }
        onSpanStarted(clientSpan, httpRequest, httpContext);
        httpContext.setAttribute(Constants.CURRENT_SPAN_CONTEXT_KEY, clientSpan);
    } catch (Exception e) {
        log.error("Could not start client tracing span.", e);
    }
}

Example 2 with Span

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

the class ScopeManagerTraceContext method pop.

/**
 * Deactivates the current active span and returns it. If there is no active span returns null.
 */
@Override
public Span pop() {
    Scope scope = scopeManager.active();
    if (scope == null) {
        return null;
    }
    Span span = scope.span();
    scope.close();
    return span;
}

Example 3 with Span

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

the class ScopeManagerTraceContextTest method getCurrentSpan.

@Test
public void getCurrentSpan() throws Exception {
    traceContext.push(span);
    Span actual = traceContext.getCurrentSpan();
    Assert.assertEquals(span, actual);
}

Example 4 with Span

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

the class ClientSpanCreationFilter method filter.

@Override
public void filter(ClientRequestContext clientRequestContext) throws IOException {
    Span currentActiveSpan = tracer.activeSpan();
    Tracer.SpanBuilder clientSpanBuilder = tracer.buildSpan(clientRequestContext.getMethod());
    if (currentActiveSpan != null) {
        clientSpanBuilder.asChildOf(currentActiveSpan);
    }
    Span clientSpan = clientSpanBuilder.start();
    // we assume there are no more spans created for this RPC request, therefore we do not need
    // to make the span active in the thread. Instead we store it in the clientRequestContext,
    // from where the resporse filter can retrieve it and finish the span.
    clientRequestContext.setProperty(Constants.CURRENT_SPAN_CONTEXT_KEY, clientSpan);
    Tags.SPAN_KIND.set(clientSpan, Tags.SPAN_KIND_CLIENT);
    Tags.HTTP_URL.set(clientSpan, clientRequestContext.getUri().toString());
    Tags.PEER_HOSTNAME.set(clientSpan, clientRequestContext.getUri().getHost());
}

Example 5 with Span

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

the class ClientSpanInjectionFilter method filter.

@Override
public void filter(ClientRequestContext clientRequestContext, ClientResponseContext clientResponseContext) throws IOException {
    try {
        Span clientSpan = (io.opentracing.Span) clientRequestContext.getProperty(Constants.CURRENT_SPAN_CONTEXT_KEY);
        if (clientSpan != null) {
            Tags.HTTP_STATUS.set(clientSpan, clientResponseContext.getStatus());
            clientSpan.finish();
        }
    } catch (Exception e) {
        log.error("Client Span Injection Filter Response:", e);
    }
