Class TargetGroupHealthCheck


  • public final class TargetGroupHealthCheck
    extends java.lang.Object
    • Method Detail

      • enabled

        public java.util.Optional<java.lang.Boolean> enabled()
        Returns:
        Whether health checks are enabled. Defaults to `true`.
      • healthyThreshold

        public java.util.Optional<java.lang.Integer> healthyThreshold()
        Returns:
        Number of consecutive health check successes required before considering a target healthy. The range is 2-10. Defaults to 3.
      • interval

        public java.util.Optional<java.lang.Integer> interval()
        Returns:
        Approximate amount of time, in seconds, between health checks of an individual target. The range is 5-300. For `lambda` target groups, it needs to be greater than the timeout of the underlying `lambda`. Defaults to 30.
      • matcher

        public java.util.Optional<java.lang.String> matcher()
        Returns:
        The HTTP or gRPC codes to use when checking for a successful response from a target. The `health_check.protocol` must be one of `HTTP` or `HTTPS` or the `target_type` must be `lambda`. Values can be comma-separated individual values (e.g., "200,202") or a range of values (e.g., "200-299"). * For gRPC-based target groups (i.e., the `protocol` is one of `HTTP` or `HTTPS` and the `protocol_version` is `GRPC`), values can be between `0` and `99`. The default is `12`. * When used with an Application Load Balancer (i.e., the `protocol` is one of `HTTP` or `HTTPS` and the `protocol_version` is not `GRPC`), values can be between `200` and `499`. The default is `200`. * When used with a Network Load Balancer (i.e., the `protocol` is one of `TCP`, `TCP_UDP`, `UDP`, or `TLS`), values can be between `200` and `599`. The default is `200-399`. * When the `target_type` is `lambda`, values can be between `200` and `499`. The default is `200`.
      • path

        public java.util.Optional<java.lang.String> path()
        Returns:
        Destination for the health check request. Required for HTTP/HTTPS ALB and HTTP NLB. Only applies to HTTP/HTTPS. * For HTTP and HTTPS health checks, the default is `/`. * For gRPC health checks, the default is `/Amazon Web Services.ALB/healthcheck`.
      • port

        public java.util.Optional<java.lang.String> port()
        Returns:
        The port the load balancer uses when performing health checks on targets. Valid values are either `traffic-port`, to use the same port as the target group, or a valid port number between `1` and `65536`. Default is `traffic-port`.
      • protocol

        public java.util.Optional<java.lang.String> protocol()
        Returns:
        Protocol the load balancer uses when performing health checks on targets. Must be one of `TCP`, `HTTP`, or `HTTPS`. The `TCP` protocol is not supported for health checks if the protocol of the target group is `HTTP` or `HTTPS`. Default is `HTTP`. Cannot be specified when the `target_type` is `lambda`.
      • timeout

        public java.util.Optional<java.lang.Integer> timeout()
        Returns:
        Amount of time, in seconds, during which no response from a target means a failed health check. The range is 2–120 seconds. For target groups with a protocol of HTTP, the default is 6 seconds. For target groups with a protocol of TCP, TLS or HTTPS, the default is 10 seconds. For target groups with a protocol of GENEVE, the default is 5 seconds. If the target type is lambda, the default is 30 seconds.
      • unhealthyThreshold

        public java.util.Optional<java.lang.Integer> unhealthyThreshold()
        Returns:
        Number of consecutive health check failures required before considering a target unhealthy. The range is 2-10. Defaults to 3.
