Example 1 with DescribeTargetHealthResult

use of com.amazonaws.services.elasticloadbalancingv2.model.DescribeTargetHealthResult in project titus-control-plane by Netflix.

the class AwsLoadBalancerConnector method getLoadBalancer.

@Override
public Single<LoadBalancer> getLoadBalancer(String loadBalancerId) {
    final DescribeTargetHealthRequest request = new DescribeTargetHealthRequest().withTargetGroupArn(loadBalancerId);

    return asyncResult.observeOn(scheduler).map(result -> {
        connectorMetrics.success(AwsLoadBalancerConnectorMetrics.AwsLoadBalancerMethods.DescribeTargetHealth, startTime);
        Set<String> ips = result.getTargetHealthDescriptions().stream().map(description -> description.getTarget().getId()).collect(Collectors.toSet());
        return new LoadBalancer(loadBalancerId, LoadBalancer.State.ACTIVE, ips);
    }).onErrorResumeNext(throwable -> {
