R66ConstraintLimitHandler

public R66ConstraintLimitHandler(boolean useJdKCpuLimit,
                                 double lowcpuLimit,
                                 double highcpuLimit,
                                 double percentageDecrease,
                                 org.jboss.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)

R66ConstraintLimitHandler

public R66ConstraintLimitHandler(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)
