java.lang.Object

com.netflix.hystrix.metric.consumer.RollingThreadPoolMaxConcurrencyStream

public class RollingThreadPoolMaxConcurrencyStream
extends RollingConcurrencyStream

Maintains a stream of max-concurrency This gets calculated using a rolling window of t1 milliseconds. This window has b buckets. Therefore, a new rolling-max is produced every t2 (=t1/b) milliseconds t1 = HystrixThreadPoolProperties.metricsRollingStatisticalWindowInMilliseconds() b = HystrixThreadPoolProperties.metricsRollingStatisticalWindowBuckets() This value gets cached in this class. It may be queried using RollingConcurrencyStream.getLatestRollingMax() This is a stable value - there's no peeking into a bucket until it is emitted
