Example 6 with SpanBuilder

use of io.opentelemetry.api.trace.SpanBuilder in project wildfly by wildfly.

the class OpenTelemetryContainerFilter method filter.

@Override

    if (!enabled) {
        return Span.getInvalid();
    }
    final String name = String.format(SPAN_FORMAT, caller.getSimpleName(), spanName);
    final SpanBuilder builder = getTracer(getOpenTelemetry()).spanBuilder(name);
    if (kind != null) {
