Examples with ExportMetricsServiceRequest io.opencensus.proto.agent.metrics.v1.ExportMetricsServiceRequest used on opensource projects

Example 1 with ExportMetricsServiceRequest

use of io.opencensus.proto.agent.metrics.v1.ExportMetricsServiceRequest in project instrumentation-java by census-instrumentation.

the class OcAgentMetricsExporterIntegrationTest method testExportMetrics.

@Test
public void testExportMetrics() throws InterruptedException, IOException {
    // Mock a real-life scenario in production, where Agent is not enabled at first, then enabled
    // after an outage. Users should be able to see metrics shortly after Agent is up.
    registerAllViews();
    LongGauge gauge = registerGauge();
    // Register the OcAgent Exporter first.
    // Agent is not yet up and running so Exporter will just retry connection.
    OcAgentMetricsExporter.createAndRegister(OcAgentMetricsExporterConfiguration.builder().setServiceName(SERVICE_NAME).setUseInsecure(true).setRetryInterval(RETRY_INTERVAL).setExportInterval(EXPORT_INTERVAL).build());
    doWork(5, gauge.getOrCreateTimeSeries(Collections.singletonList(LabelValue.create("First work"))));
    // Wait 3s so that all metrics get exported.
    Thread.sleep(3000);
    // No interaction with Agent so far.
    assertThat(fakeOcAgentMetricsServiceGrpc.getExportMetricsServiceRequests()).isEmpty();
    // Imagine that an outage happened, now start Agent. Exporter should be able to connect to Agent
    // after the next retry interval.
    agent.start();
    // Wait 3s for Exporter to start another attempt to connect to Agent.
    Thread.sleep(3000);
    doWork(8, gauge.getOrCreateTimeSeries(Collections.singletonList(LabelValue.create("Second work"))));
    // Wait 3s so that all metrics get exported.

    List<Metric> metricProtos = new ArrayList<>();
    for (int i = 1; i < exportRequests.size(); i++) {

}

Example 2 with ExportMetricsServiceRequest

use of io.opencensus.proto.agent.metrics.v1.ExportMetricsServiceRequest in project instrumentation-java by census-instrumentation.

the class OcAgentMetricsServiceExportRpcHandlerTest method export_createAndExport.

@Test
public void export_createAndExport() {
    OcAgentMetricsServiceExportRpcHandler exportRpcHandler = OcAgentMetricsServiceExportRpcHandler.create(getStub(serverName));
    ExportMetricsServiceRequest request = ExportMetricsServiceRequest.newBuilder().setNode(NODE).build();
