The ThreadDroppingServerLoadMonitor attempts to keep the hit rate down by increasing the disconnected time as usage increases. author:    Joe Walker [joe at getahead dot org] Field Summary final protected static  int SECONDS_MONITORED      We are recording the number of hits in the last 5 seconds. protected  int connectedTime      The time we are currently waiting before sending a browser away and asking it to reconnect. protected  int disconnectedTime      protected  HitMonitor hitMonitor      protected  int maxHitsPerSecond      Static configuration data: The max number of hits per second. We increase the poll time to compensate and reduce the load.

Maybe we should think about making this configurable. connectedTime protected int connectedTime(Code) The time we are currently waiting before sending a browser away and asking it to reconnect. disconnectedTime protected int disconnectedTime(Code) How long are we telling users to wait before they come back next hitMonitor protected HitMonitor hitMonitor(Code) Our record of the server loading maxHitsPerSecond protected int maxHitsPerSecond(Code) Static configuration data: The max number of hits per second. We increase the poll time to compensate and reduce the load. If this number is not at least half maxWaitingThreads then the USAGE_HIGH mode will not exist and the system will sublime from USAGE_LOW to USAGE_DIGG Method Detail getConnectedTime public long getConnectedTime()(Code) getDisconnectedTime public int getDisconnectedTime()(Code) setMaxHitsPerSecond public void setMaxHitsPerSecond(int maxHitsPerSecond)(Code) Parameters:   maxHitsPerSecond - the maxHitsPerSecond to set supportsStreaming public boolean supportsStreaming()(Code) threadWaitEnding public void threadWaitEnding(WaitController controller)(Code) threadWaitStarting public void threadWaitStarting(WaitController controller)(Code) Fields inherited from org.directwebremoting.impl.AbstractServerLoadMonitor final protected List<WaitController> waitControllers(Code)(Java Doc) Methods inherited from org.directwebremoting.impl.AbstractServerLoadMonitor public void shutdown()(Code)(Java Doc) public void shutdownRandomWaitControllers(int count)(Code)(Java Doc) public void threadWaitEnding(WaitController controller)(Code)(Java Doc) public void threadWaitStarting(WaitController controller)(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
