Method Detail

getRateLimiter

public static com.google.common.util.concurrent.RateLimiter getRateLimiter()

Gets streaming rate limiter. When stream_throughput_outbound_megabits_per_sec is 0, this returns rate limiter with the rate of Double.MAX_VALUE bytes per second. Rate unit is bytes per sec.

Returns:

RateLimiter with rate limit set

getCurrentStreams

public java.util.Set<javax.management.openmbean.CompositeData> getCurrentStreams()

Description copied from interface: StreamManagerMBean

Returns the current state of all ongoing streams.

Specified by:
