the class ElbService method getTargetGroupsArn.

public List<String> getTargetGroupsArn(String loadBalancerArn) {
    var request = new DescribeListenersRequest().withLoadBalancerArn(loadBalancerArn);
    int randomSleepMs = RandomTool.getRandomIntBetweenTwoNumbers(0, 3_000);
    return RetryableTool.tryNTimesWithBackoffAndRandomInitialDelayUnchecked(() -> amazonElasticLoadBalancing.get().describeListeners(request).getListeners().stream().map(Listener::getDefaultActions).flatMap(List::stream).map(Action::getTargetGroupArn).filter(// remove action that have no tg (like redirect)
    Objects::nonNull).distinct().collect(Collectors.toList()), NUM_ATTEMPTS, randomSleepMs, true);
}

Example 2 with DescribeListenersRequest

use of com.amazonaws.services.elasticloadbalancingv2.model.DescribeListenersRequest in project aws-cloudwatch-exporter by asserts.

the class TargetGroupLBMapProvider method mapLB.

@VisibleForTesting

            if (!isEmpty(listenersResponse.listeners())) {
                listenersResponse.listeners().forEach(listener -> mapListener(lbClient, labels, lbResource, listener));
            }
