Example 1 with MetricType

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

the class MetricRegistryImplTest method registerByMetadataAcceptsInstancesWithSameNameButDifferentTags.

@Test
public void registerByMetadataAcceptsInstancesWithSameNameButDifferentTags() {
    EnumSet<MetricType> types = EnumSet.allOf(MetricType.class);
    // obviously
    types.remove(MetricType.INVALID);
    // gauges cannot be created
    types.remove(MetricType.GAUGE);
    for (MetricType type : types) {
        String name = nextName();
        for (int i = 0; i < 10; i++) {
            final int n = i;
            MetadataBuilder metadata = withNameAnd(name).withType(type);
            Runnable register = () -> registry.register(metadata.build(), null, new Tag("a", "b" + n));
            // first time should work
            register.run();
            // works again as all metrics are reusable
            register.run();
        }
    }

Example 2 with MetricType

use of org.eclipse.microprofile.metrics.MetricType in project wildfly-swarm by wildfly-swarm.

the class MetricsRegistryImpl method register.

@Override

    if (metricMap.keySet().contains(name)) {

        String tname = metricCls.getGenericInterfaces()[0].getTypeName();
        tname = tname.substring(tname.lastIndexOf('.') + 1);
        tname = tname.toLowerCase();
        type = MetricType.from(tname);
    } else if (metricCls.isAnonymousClass()) {
        type = MetricType.from(metricCls.getInterfaces().length == 0 ? metricCls.getSuperclass().getInterfaces()[0] : metricCls.getInterfaces()[0]);
    } else {
        if (!metricCls.isInterface()) {
            // [0] is ok, as all our Impl classes implement exactly the one matching interface
            type = MetricType.from(metricCls.getInterfaces()[0]);
        } else {
            type = MetricType.from(metricCls);
