Example 1 with CountersReader

use of org.agrona.concurrent.status.CountersReader in project Aeron by real-logic.

the class SetControllableIdleStrategy method main.

public static void main(final String[] args) throws Exception {
    try (Aeron aeron = Aeron.connect()) {
        final CountersReader countersReader = aeron.countersReader();
        final MutableInteger id = new MutableInteger();
        id.value = -1;
        countersReader.forEach((counterId, typeId, keyBuffer, label) -> {
            if (counterId == SystemCounterDescriptor.CONTROLLABLE_IDLE_STRATEGY.id() && label.equals(SystemCounterDescriptor.CONTROLLABLE_IDLE_STRATEGY.label())) {
                id.value = counterId;
            }
        });
        if (-1 != id.value) {
            final StatusIndicator statusIndicator = new UnsafeBufferStatusIndicator(countersReader.valuesBuffer(), id.value);
            final int status = Integer.parseInt(args[0]);
            statusIndicator.setOrdered(status);
            System.out.println("Set ControllableIdleStrategy status to " + status);
        } else {
            System.out.println("Could not find ControllableIdleStrategy status.");
        }
    }
}

Example 2 with CountersReader

use of org.agrona.concurrent.status.CountersReader in project Aeron by real-logic.

the class AeronStat method mapCounters.

    System.out.println("Command `n Control file " + cncFile);
    final MappedByteBuffer cncByteBuffer = IoUtil.mapExistingFile(cncFile, "cnc");

    }
    return new CountersReader(createCountersMetaDataBuffer(cncByteBuffer, cncMetaData), createCountersValuesBuffer(cncByteBuffer, cncMetaData));
