Examples with Type org.eclipse.microprofile.metrics.MetricRegistry.Type used on opensource projects

Example 1 with Type

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

the class MetricsServiceImpl method processMetadataToAnnotations.

private static void processMetadataToAnnotations(MetricsContextImpl context, MonitoringDataCollector collector) {
    RegisteredMetric metric = context.pollNewlyRegistered();
    while (metric != null) {
        MetricID metricID = metric.id;
        Type scope = metric.scope;
        MetricRegistry registry = context.getRegistry(scope);
        MonitoringDataCollector metricCollector = tagCollector(context.getName(), metricID, collector);
        Metadata metadata = registry.getMetadata(metricID.getName());
        String suffix = "Count";
        String property = "Count";
        boolean isGauge = metadata.getTypeRaw() == MetricType.GAUGE;
        if (isGauge) {
            suffix = getMetricUnitSuffix(metadata.unit());
            property = "Value";
        }
        // Note that by convention an annotation with value 0 done before the series collected any value is considered permanent
        metricCollector.annotate(toName(metricID, suffix), 0, false, metadataToAnnotations(context.getName(), scope, metadata, property));
        metric = context.pollNewlyRegistered();
