Example 1 with SamzaHistogram

use of org.apache.samza.metrics.SamzaHistogram in project samza by apache.

the class TranslatorOutputMetricsMapFunction method init.

/**
 * initializes the TranslatorOutputMetricsMapFunction before any message is processed
 * @param context the {@link Context} for this task
 */
@Override
public void init(Context context) {
    ContainerContext containerContext = context.getContainerContext();
    metricsRegistry = containerContext.getContainerMetricsRegistry();
    processingTime = new SamzaHistogram(metricsRegistry, logicalOpId, TranslatorConstants.PROCESSING_TIME_NAME);
    outputEvents = metricsRegistry.newCounter(logicalOpId, TranslatorConstants.OUTPUT_EVENTS_NAME);
    outputEvents.clear();
}

Example 2 with SamzaHistogram

use of org.apache.samza.metrics.SamzaHistogram in project samza by apache.
