Class HealthCheck

    • Method Detail

      • target

        public final String target()

        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.

        Returns:

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

      • interval

        public final Integer interval()

        The approximate interval, in seconds, between health checks of an individual instance.

        Returns:
        The approximate interval, in seconds, between health checks of an individual instance.
      • timeout

        public final Integer timeout()

        The amount of time, in seconds, during which no response means a failed health check.

        This value must be less than the Interval value.

        Returns:
        The amount of time, in seconds, during which no response means a failed health check.

        This value must be less than the Interval value.

      • unhealthyThreshold

        public final Integer unhealthyThreshold()

        The number of consecutive health check failures required before moving the instance to the Unhealthy state.

        Returns:
        The number of consecutive health check failures required before moving the instance to the Unhealthy state.
      • healthyThreshold

        public final Integer healthyThreshold()

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

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

        public final int hashCode()
        Overrides:
        hashCode in class Object
      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
                                                      Class<T> clazz)
