Examples of io.netty.handler.traffic.TrafficCounter

io.netty.handler.traffic.TrafficCounter
TrafficCounter is associated with {@link AbstractTrafficShapingHandler}.

A TrafficCounter has for goal to count the traffic in order to enable to limit the traffic or not, globally or per channel. It compute statistics on read and written bytes at the specified interval and call back the {@link AbstractTrafficShapingHandler} doAccounting method at everyspecified interval. If this interval is set to 0, therefore no accounting will be done and only statistics will be computed at each receive or write operations.

        long readsPerSec = (lastReads / interval) * 1000;
        long writesPerSec = (lastWrites / interval) * 1000;
        metrics.setLastReads(readsPerSec);
        metrics.setLastWrites(writesPerSec);


        TrafficCounter traffic = trafficCounter();
        long readThroughput = traffic.lastReadThroughput();
        long writeThroughput = traffic.lastWriteThroughput();
        metrics.setReadThroughput(readThroughput);
        metrics.setWriteThroughput(writeThroughput);


        if(logger.isInfoEnabled()) {
            if(lastReads > 0 || lastWrites > 0) {
