Example 1 with SimpleTextOutputStream

use of org.apache.pulsar.common.util.SimpleTextOutputStream in project incubator-pulsar by apache.

the class PrometheusMetricsGenerator method generate.

public static void generate(PulsarService pulsar, boolean includeTopicMetrics, OutputStream out) throws IOException {
    ByteBuf buf = ByteBufAllocator.DEFAULT.heapBuffer();
    try {
        SimpleTextOutputStream stream = new SimpleTextOutputStream(buf);

        NamespaceStatsAggregator.generate(pulsar, includeTopicMetrics, stream);
        FunctionsStatsGenerator.generate(pulsar.getWorkerService(), pulsar.getConfiguration().getClusterName(), stream);
        out.write(buf.array(), buf.arrayOffset(), buf.readableBytes());
    } finally {
