HystrixYammerMetricsPublisher

　　繼承HystrixMetricsPublisher，創建HystrixYammerMetricsPublisherCommand、HystrixYammerMetricsPublisherThreadPool、HystrixYammerMetricsPublisherCollapser。

@Overridepublic HystrixMetricsPublisherCommand getMetricsPublisherForCommand(HystrixCommandKey commandKey, HystrixCommandGroupKey commandGroupKey, HystrixCommandMetrics metrics, HystrixCircuitBreaker circuitBreaker, HystrixCommandProperties properties) {return new HystrixYammerMetricsPublisherCommand(commandKey, commandGroupKey, metrics, circuitBreaker, properties, metricsRegistry);}@Overridepublic HystrixMetricsPublisherThreadPool getMetricsPublisherForThreadPool(HystrixThreadPoolKey threadPoolKey, HystrixThreadPoolMetrics metrics, HystrixThreadPoolProperties properties) {return new HystrixYammerMetricsPublisherThreadPool(threadPoolKey, metrics, properties, metricsRegistry);}@Overridepublic HystrixMetricsPublisherCollapser getMetricsPublisherForCollapser(HystrixCollapserKey collapserKey, HystrixCollapserMetrics metrics, HystrixCollapserProperties properties) {return new HystrixYammerMetricsPublisherCollapser(collapserKey, metrics, properties, metricsRegistry);}

?HystrixYammerMetricsPublisherCommand

　　從HystrixCommandMetrics獲取數據，然后設置到MetricsRegistry中。

例如：

protected void createExecutionLatencyPercentileGauge(final String name, final double percentile) {metricsRegistry.newGauge(createMetricName(name), new Gauge<Integer>() {@Overridepublic Integer value() {return metrics.getExecutionTimePercentile(percentile);}});}

?HystrixYammerMetricsPublisherThreadPool

　　從HystrixThreadPoolMetrics獲取數據，然后設置到MetricsRegistry中。

例如：

metricsRegistry.newGauge(createMetricName("rollingMaxActiveThreads"), new Gauge<Number>() {@Overridepublic Number value() {return metrics.getRollingMaxActiveThreads();}});

HystrixYammerMetricsPublisherCollapser

　　從HystrixCollapserMetrics獲取數據，然后設置到MetricsRegistry中。

例如：

metricsRegistry.newGauge(createMetricName("shardSize_percentile_50"), new Gauge<Integer>() {@Overridepublic Integer value() {return metrics.getShardSizePercentile(50);}});
