AWSElasticLoadBalancingHealthCheck

Objective-C

@interface AWSElasticLoadBalancingHealthCheck

Swift

class AWSElasticLoadBalancingHealthCheck

Information about a health check.

Required parameters: [Target, Interval, Timeout, UnhealthyThreshold, HealthyThreshold]

  • The number of consecutive health checks successes required before moving the instance to the Healthy state.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable healthyThreshold;

    Swift

    var healthyThreshold: NSNumber? { get set }
  • The approximate interval, in seconds, between health checks of an individual instance.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable interval;

    Swift

    var interval: NSNumber? { get set }
  • The instance being checked. The protocol is either TCP, HTTP, HTTPS, or SSL. The range of valid ports is one (1) through 65535.

    TCP is the default, specified as a TCP: port pair, for example “TCP:5000”. In this case, a health check simply attempts to open a TCP connection to the instance on the specified port. Failure to connect within the configured timeout is considered unhealthy.

    SSL is also specified as SSL: port pair, for example, SSL:5000.

    For HTTP/HTTPS, you must include a ping path in the string. HTTP is specified as a HTTP:port;/;PathToPing; grouping, for example “HTTP:80/weather/us/wa/seattle”. In this case, a HTTP GET request is issued to the instance on the given port and path. Any answer other than “200 OK” within the timeout period is considered unhealthy.

    The total length of the HTTP ping target must be 1024 16-bit Unicode characters or less.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable target;

    Swift

    var target: String? { get set }
  • The amount of time, in seconds, during which no response means a failed health check.

    This value must be less than the Interval value.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable timeout;

    Swift

    var timeout: NSNumber? { get set }
  • The number of consecutive health check failures required before moving the instance to the Unhealthy state.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable unhealthyThreshold;

    Swift

    var unhealthyThreshold: NSNumber? { get set }
