Examples with DefaultTracer com.newrelic.agent.tracers.DefaultTracer used on opensource projects

Example 1 with DefaultTracer

use of com.newrelic.agent.tracers.DefaultTracer in project newrelic-java-agent by newrelic.

the class TransactionStateImpl method getTracer.

/**
 * Get tracer for weaved code and XML instrumentation (no tracer factory)
 */
@Override
public Tracer getTracer(Transaction tx, final Object invocationTarget, final ClassMethodSignature sig, final String metricName, final int flags) {
    TransactionActivity activity = tx.getTransactionActivity();
    if (tx.isIgnore() || activity.isTracerStartLocked()) {
        return null;
    }
    Tracer tracer;
    final MetricNameFormat mnf = MetricNameFormats.getFormatter(invocationTarget, sig, metricName, flags);
    if (TracerFlags.isDispatcher(flags)) {
        tracer = new OtherRootTracer(tx, sig, invocationTarget, mnf);
    } else {
        tracer = new DefaultTracer(tx, sig, invocationTarget, mnf, flags);
    }
    return tracerStarted(tx, sig, tracer);
}

Example 2 with DefaultTracer

use of com.newrelic.agent.tracers.DefaultTracer in project newrelic-java-agent by newrelic.

the class InstrumentationImpl method startTracer.

// Preconditions are met: start a new tracer on this thread. There may not be a Transaction on this thread. Code
// in this path MUST NOT attempt to touch the Transaction or do anything that might bring one into existence. This
// inconvenience is absolutely critical to the performance of our async instrumentation.
private Tracer startTracer(TransactionActivity txa, Object target, int signatureId, String metricName, int flags) {
    ClassMethodSignature sig = ClassMethodSignatures.get().get(signatureId);
    MetricNameFormat mnf = MetricNameFormats.getFormatter(target, sig, metricName, flags);
    Tracer tracer;
    if (TracerFlags.isRoot(flags)) {
        // Dispatcher || Async
        tracer = new OtherRootTracer(txa, sig, target, mnf, flags, System.nanoTime());
    } else {
        tracer = new DefaultTracer(txa, sig, target, mnf, flags);
    }
    txa.tracerStarted(tracer);
    return tracer;
}

Example 3 with DefaultTracer

use of com.newrelic.agent.tracers.DefaultTracer in project newrelic-java-agent by newrelic.

    Transaction tx = Transaction.getTransaction();
    ClassMethodSignature sig = new ClassMethodSignature(getClass().getName(), "dude", "()V");
    return new DefaultTracer(tx, sig, this, new SimpleMetricNameFormat("test"));
