Constructor Detail

FtpConstraintLimitHandler

public FtpConstraintLimitHandler(long timeoutcon,
                         boolean useJdkCpuLimit,
                         double lowcpuLimit,
                         double highcpuLimit,
                         double percentageDecrease,
                         io.netty.handler.traffic.GlobalTrafficShapingHandler handler,
                         long delay,
                         long limitLowBandwidth)

Parameters:

useJdkCpuLimit - True to use JDK Cpu native or False for JavaSysMon

lowcpuLimit - for proactive cpu limitation (throttling bandwidth) (0<= x < 1 & highcpulimit)

highcpuLimit - for proactive cpu limitation (throttling bandwidth) (0<= x <= 1) 0 meaning no throttle activated

percentageDecrease - for proactive cpu limitation, throttling bandwidth reduction (0 < x < 1) as 0.25 for 25% of reduction

handler - the GlobalTrafficShapingHandler associated (null to have no proactive cpu limitation)

delay - the delay between 2 tests for proactive cpu limitation

limitLowBandwidth - the minimal bandwidth (read or write) to apply when decreasing bandwidth (low limit = 4096)

FtpConstraintLimitHandler

public FtpConstraintLimitHandler(long timeoutcon,
                         boolean useCpuLimit,
                         boolean useJdKCpuLimit,
                         double cpulimit,
                         int channellimit)

Parameters:

useCpuLimit - True to enable cpuLimit on connection check

useJdKCpuLimit - True to use JDK Cpu native or False for JavaSysMon

cpulimit - high cpu limit (0<= x < 1) to refuse new connections

channellimit - number of connection limit (0<= x)

                         double percentageDecrease,
                         io.netty.handler.traffic.GlobalTrafficShapingHandler handler,
                         long delay,
