HystrixServoMetricsPublisher

　　繼承HystrixMetricsPublisher，創建HystrixServoMetricsPublisherCommand、HystrixServoMetricsPublisherThreadPool、HystrixServoMetricsPublisherCollapser。

    @Override
    public HystrixMetricsPublisherCommand getMetricsPublisherForCommand(HystrixCommandKey commandKey, HystrixCommandGroupKey commandGroupKey, HystrixCommandMetrics metrics, HystrixCircuitBreaker circuitBreaker, HystrixCommandProperties properties) {
        
 
return new HystrixServoMetricsPublisherCommand(commandKey, commandGroupKey, metrics, circuitBreaker, properties);
    }

    @Override
    public HystrixMetricsPublisherThreadPool getMetricsPublisherForThreadPool(HystrixThreadPoolKey threadPoolKey, HystrixThreadPoolMetrics metrics, HystrixThreadPoolProperties properties) {
        
 
return new HystrixServoMetricsPublisherThreadPool(threadPoolKey, metrics, properties);
    }

    @Override
    public HystrixMetricsPublisherCollapser getMetricsPublisherForCollapser(HystrixCollapserKey collapserKey, HystrixCollapserMetrics metrics, HystrixCollapserProperties properties) {
        
 
return new HystrixServoMetricsPublisherCollapser(collapserKey, metrics, properties);
    }

HystrixServoMetricsPublisherCommand

　　從HystrixCommandMetrics獲取數據，然後設置到DefaultMonitorRegistry中。

HystrixServoMetricsPublisherThreadPool

　　從HystrixThreadPoolMetrics獲取數據，然後設置到DefaultMonitorRegistry中。

HystrixServoMetricsPublisherCollapser

　　從HystrixCollapserMetrics獲取數據，然後設置到DefaultMonitorRegistry中。
