            }
            node = node.addChild(tag.value(), measurement);
        }
    }

Example 2 with Measurement

use of com.netflix.spectator.api.Measurement in project incubator-servicecomb-java-chassis by apache.

the class Utils method createStageNode.

public static MeasurementNode createStageNode(String stage, double count, double totalTime, double max) {
    Id id = registry.createId("id").withTag(Statistic.count);
    Measurement countMeasurement = new Measurement(id.withTag(Statistic.count), 0, count);
    Measurement totalTimeMeasurement = new Measurement(id.withTag(Statistic.totalTime), 0, totalTime);
    Measurement maxMeasurement = new Measurement(id.withTag(Statistic.max), 0, max);
    MeasurementNode stageNode = new MeasurementNode(stage, null);
    stageNode.addChild(Statistic.count.name(), countMeasurement);
    stageNode.addChild(Statistic.totalTime.name(), totalTimeMeasurement);
    stageNode.addChild(Statistic.max.name(), maxMeasurement);
    return stageNode;
}

Example 3 with Measurement

use of com.netflix.spectator.api.Measurement in project kork by spinnaker.

the class StackdriverWriter method addMeterToTimeSeries.

/**
 * Add a TimeSeries for each appropriate meter measurement.
 */
void addMeterToTimeSeries(Registry registry, Meter meter, List<TimeSeries> tsList) {
    Iterable<Measurement> measurements = meter.measure();

        String descriptorType = cache.idToDescriptorType(measurement.id());
        tsList.add(measurementToTimeSeries(descriptorType, registry, meter, measurement));
    }
}

Example 4 with Measurement

use of com.netflix.spectator.api.Measurement in project kork by spinnaker.

the class StackdriverWriter method transformTimerMeasurements.

/**
 * Transform timer measurements from a composite with count/totalTime tags
 * to a pair of specialized measurements without the "statistic" tag.
 *
 * This is so we can have different units for the measurement
 * MetricDescriptor to note that the totalTime is in nanoseconds.
 *
 * @param measurements
 *   The list of measurements to transform come from a Timer meter.
 *
 * @return
 *   A list of measurements, probably the same as the original size, where
 *   each of the elements corresponds to an original element but does not
 *   have the "statistic" label. Where the original was "count", the new
 *   id name will have a "__count" suffix and "__totalTime" for the
 *   "totalTime" statistic. The base name will be the same as the original.

    ArrayList<Measurement> result = new ArrayList<Measurement>();
    for (Measurement measurement : measurements) {
        if (!measurementFilter.test(measurement)) {
            continue;
        }
        Id id = timerBaseIds.computeIfAbsent(measurement.id(), k -> deriveBaseTimerId(k));
        result.add(new Measurement(id, measurement.timestamp(), measurement.value()));
    }
