Examples with MetricsReporter org.apache.kafka.common.metrics.MetricsReporter used on opensource projects

Example 1 with MetricsReporter

use of org.apache.kafka.common.metrics.MetricsReporter in project ksql by confluentinc.

the class MetricCollectors method initialize.

// visible for testing.
// We need to call this from the MetricCollectorsTest because otherwise tests clobber each
// others metric data. We also need it from the KsqlEngineMetricsTest
public static void initialize() {
    MetricConfig metricConfig = new MetricConfig().samples(100).timeWindow(1000, TimeUnit.MILLISECONDS);
    List<MetricsReporter> reporters = new ArrayList<>();
    reporters.add(new JmxReporter("io.confluent.ksql.metrics"));
    // Replace all static contents other than Time to ensure they are cleaned for tests that are
    // not aware of the need to initialize/cleanup this test, in case test processes are reused.
    // Tests aware of the class clean everything up properly to get the state into a clean state,
    // a full, fresh instantiation here ensures something like KsqlEngineMetricsTest running after
    // another test that used MetricsCollector without running cleanUp will behave correctly.
    metrics = new Metrics(metricConfig, reporters, new SystemTime());
    collectorMap = new ConcurrentHashMap<>();

Example 2 with MetricsReporter

use of org.apache.kafka.common.metrics.MetricsReporter in project apache-kafka-on-k8s by banzaicloud.
