Example 1 with Stats

use of com.datatorrent.api.Stats in project apex-core by apache.

the class Node method reportStats.

protected void reportStats(ContainerStats.OperatorStats stats, long windowId) {

        portStats.endWindowTimestamp = endWindowEmitTime;
        stats.outputPorts.add(portStats);
    }
    controlTupleCount = 0;
    long currentCpuTime = tmb.getCurrentThreadCpuTime();
    stats.cpuTimeUsed = currentCpuTime - lastSampleCpuTime;
