Examples with TaskManagerMetricsInfo org.apache.flink.runtime.rest.messages.taskmanager.TaskManagerMetricsInfo used on opensource projects

Example 1 with TaskManagerMetricsInfo

use of org.apache.flink.runtime.rest.messages.taskmanager.TaskManagerMetricsInfo in project flink by apache.

the class TaskManagerDetailsHandlerTest method testTaskManagerMetricsInfoExtraction.

@Test
public void testTaskManagerMetricsInfoExtraction() throws RestHandlerException, ExecutionException, InterruptedException, JsonProcessingException, HandlerRequestException {
    initializeMetricStore(metricFetcher.getMetricStore());
    resourceManagerGateway.setRequestTaskManagerDetailsInfoFunction(taskManagerId -> CompletableFuture.completedFuture(new TaskManagerInfoWithSlots(createEmptyTaskManagerInfo(), Collections.emptyList())));
    HandlerRequest<EmptyRequestBody> request = createRequest();
    TaskManagerDetailsInfo taskManagerDetailsInfo = testInstance.handleRequest(request, resourceManagerGateway).get();
    TaskManagerMetricsInfo actual = taskManagerDetailsInfo.getTaskManagerMetricsInfo();
    TaskManagerMetricsInfo expected = new TaskManagerMetricsInfo(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 15L, 16L, 17L, 18L, 19L, 20L, Collections.emptyList());
    ObjectMapper objectMapper = new ObjectMapper();
    String actualJson = objectMapper.writeValueAsString(actual);
    String expectedJson = objectMapper.writeValueAsString(expected);
    assertThat(actualJson, is(expectedJson));
}

Example 2 with TaskManagerMetricsInfo

use of org.apache.flink.runtime.rest.messages.taskmanager.TaskManagerMetricsInfo in project flink by apache.

the class TaskManagerDetailsHandler method handleRequest.

@Override
protected CompletableFuture<TaskManagerDetailsInfo> handleRequest(@Nonnull HandlerRequest<EmptyRequestBody> request, @Nonnull ResourceManagerGateway gateway) throws RestHandlerException {
    final ResourceID taskManagerResourceId = request.getPathParameter(TaskManagerIdPathParameter.class);
    CompletableFuture<TaskManagerInfoWithSlots> taskManagerInfoWithSlotsFuture = gateway.requestTaskManagerDetailsInfo(taskManagerResourceId, timeout);
    metricFetcher.update();
    return taskManagerInfoWithSlotsFuture.thenApply((taskManagerInfoWithSlots) -> {
        final MetricStore.TaskManagerMetricStore tmMetrics = metricStore.getTaskManagerMetricStore(taskManagerResourceId.getResourceIdString());
        final TaskManagerMetricsInfo taskManagerMetricsInfo;
        if (tmMetrics != null) {
            log.debug("Create metrics info for TaskManager {}.", taskManagerResourceId.getStringWithMetadata());
            taskManagerMetricsInfo = createTaskManagerMetricsInfo(tmMetrics);
        } else {
            log.debug("No metrics for TaskManager {}.", taskManagerResourceId.getStringWithMetadata());
            taskManagerMetricsInfo = TaskManagerMetricsInfo.empty();
        }
        return new TaskManagerDetailsInfo(taskManagerInfoWithSlots, taskManagerMetricsInfo);
    }).exceptionally((Throwable throwable) -> {
        final Throwable strippedThrowable = ExceptionUtils.stripExecutionException(throwable);
        if (strippedThrowable instanceof UnknownTaskExecutorException) {
            throw new CompletionException(new RestHandlerException("Could not find TaskExecutor " + taskManagerResourceId + '.', HttpResponseStatus.NOT_FOUND, strippedThrowable));
        } else {
            throw new CompletionException(strippedThrowable);
        }
    });
