Represents the outlier detection for a listener.

Example

// Cloud Map service discovery is currently required for host ejection by outlier detection
const vpc = new ec2.Vpc(this, 'vpc');
const namespace = new cloudmap.PrivateDnsNamespace(this, 'test-namespace', {
    vpc,
    name: 'domain.local',
});
const service = namespace.createService('Svc');

declare const mesh: appmesh.Mesh;
const node = mesh.addVirtualNode('virtual-node', {
  serviceDiscovery: appmesh.ServiceDiscovery.cloudMap(service),
  listeners: [appmesh.VirtualNodeListener.http({
    outlierDetection: {
      baseEjectionDuration: Duration.seconds(10),
      interval: Duration.seconds(30),
      maxEjectionPercent: 50,
      maxServerErrors: 5,
    },
  })],
});
