Examples with ClientAffinityStats org.voltdb.client.ClientAffinityStats used on opensource projects

Example 1 with ClientAffinityStats

use of org.voltdb.client.ClientAffinityStats in project voltdb by VoltDB.

the class SyncBenchmark method printStatistics.

/**
     * Prints a one line update on performance that can be printed
     * periodically during a benchmark.
     */
public synchronized void printStatistics() {
    ClientStatsContext statscontext = periodicStatsContext.fetchAndResetBaseline();
    ClientAffinityStats affinityStats = statscontext.getAggregateAffinityStats();
    ClientStats stats = statscontext.getStats();
    long time = Math.round((stats.getEndTimestamp() - benchmarkStartTS) / 1000.0);
    System.out.printf("%02d:%02d:%02d ", time / 3600, (time / 60) % 60, time % 60);
    System.out.printf("Throughput %d/s, ", stats.getTxnThroughput());
    System.out.printf("Aborts/Failures %d/%d, ", stats.getInvocationAborts(), stats.getInvocationErrors());
    System.out.printf("Avg/95%% Latency %.2f/%.2fms, ", stats.getAverageLatency(), stats.kPercentileLatencyAsDouble(0.95));
    System.out.printf("%d AW, %d AR, %d RRW, %d RRR\n", affinityStats.getAffinityWrites(), affinityStats.getAffinityReads(), affinityStats.getRrWrites(), affinityStats.getRrReads());

Example 2 with ClientAffinityStats
