Example 1 with Gauge

use of org.eclipse.microprofile.metrics.annotation.Gauge in project Payara by payara.

the class MetricsResolver method getMetadata.

public <T extends Annotation> Metadata getMetadata(String name, T annotation) {
    Metadata metadata;
    String[] tags;
    if (Counted.class.isInstance(annotation)) {
        Counted counted = (Counted) annotation;
        metadata = new Metadata(name, counted.displayName(), counted.description(), COUNTER, counted.unit());
        tags = counted.tags();
    } else if (Gauge.class.isInstance(annotation)) {
        Gauge gauge = (Gauge) annotation;
        metadata = new Metadata(name, gauge.displayName(), gauge.description(), GAUGE, gauge.unit());
        tags = gauge.tags();
    } else if (Metered.class.isInstance(annotation)) {
        Metered metered = (Metered) annotation;
        metadata = new Metadata(name, metered.displayName(), metered.description(), METERED, metered.unit());
        tags = metered.tags();
    } else if (Timed.class.isInstance(annotation)) {
        Timed timed = (Timed) annotation;

    } else {
        throw new IllegalArgumentException("Unsupported Metrics [" + annotation.getClass().getName() + "]");
    }
    for (String tag : tags) {
        metadata.addTag(tag);
    }
    return metadata;

Example 2 with Gauge

use of org.eclipse.microprofile.metrics.annotation.Gauge in project Payara by payara.

the class MetricsInterceptor method registerMetrics.

    MetricsResolver.Of<Counted> counted = resolver.counted(bean, element);
    if (counted.isPresent()) {
        registry.counter(counted.metadata());
    }
    MetricsResolver.Of<Metered> metered = resolver.metered(bean, element);

        if (gauge.isPresent()) {
            registry.register(gauge.metricName(), new GaugeImpl((Method) element, target), gauge.metadata());
        }
    }
