Example 2 with ServerReporter

use of com.baidu.hugegraph.metrics.ServerReporter in project incubator-hugegraph by apache.

the class GraphManager method addMetrics.

private void addMetrics(HugeConfig config) {
    final MetricManager metric = MetricManager.INSTANCE;
    // Force to add server reporter
    ServerReporter reporter = ServerReporter.instance(metric.getRegistry());
    reporter.start(60L, TimeUnit.SECONDS);

        int count = caches.size();
        if (count != lastCachesSize.get()) {
            // Update if caches changed (effect in the next report period)
