## Interface MemberHealthConfig

- All Known Subinterfaces:
    GemFireHealthConfig

  Deprecated.
  as of 7.0 use the `management` package instead

      public interface MemberHealthConfig

  Provides configuration information relating to the health of a member of a GemFire distributed system.

  If any of the following criteria is true, then a member is considered to be in `OKAY_HEALTH`.

  - The size of the VM process is too large.
  - There are too many enqueued incoming/outgoing messages.
  - Too many message sends `timeout` while waiting for a reply.
  If any of the following criteria is true, then a member is considered to be in `POOR_HEALTH`.
  Since:
    GemFire 3.5

        Constant Field Values

    - #### DEFAULT_MAX_MESSAGE_QUEUE_SIZE

          static final long DEFAULT_MAX_MESSAGE_QUEUE_SIZE

      See Also:
        Constant Field Values

    - #### DEFAULT_MAX_REPLY_TIMEOUTS

          static final long DEFAULT_MAX_REPLY_TIMEOUTS

      Deprecated.
      The default maximum multicast retransmission ratio. The default value is 0.20 (twenty percent of messages retransmitted)
      See Also:
        Constant Field Values

  - ### Method Detail

    - #### getMaxVMProcessSize

          long getMaxVMProcessSize()

      Deprecated.
      Returns the maximum VM process size (in megabytes) of a healthy member of the distributed system.
      See Also:
        `DEFAULT_MAX_VM_PROCESS_SIZE`

    - #### setMaxVMProcessSize

          void setMaxVMProcessSize(long size)

      Deprecated.
      Sets the maximum VM process size (in megabytes) of a healthy member of the distributed system.
      See Also:
        `getMaxVMProcessSize()`

    - #### getMaxMessageQueueSize

          long getMaxMessageQueueSize()

      Deprecated.
      Returns the maximum number of enqueued incoming or outgoing messages that a healthy member of a distributed system can have.
      See Also:
        `DEFAULT_MAX_MESSAGE_QUEUE_SIZE`

    - #### setMaxMessageQueueSize

          void setMaxMessageQueueSize(long maxMessageQueueSize)

      Deprecated.
      Sets the maximum number of enqueued incoming or outgoing messages that a healthy member of a distributed system can have.
      See Also:
        `getMaxMessageQueueSize()`

    - #### getMaxReplyTimeouts

          long getMaxReplyTimeouts()

      Deprecated.
      Returns the maximum number message replies that can timeout in a healthy member.
      See Also:
        `DEFAULT_MAX_REPLY_TIMEOUTS`

    - #### setMaxReplyTimeouts

          void setMaxReplyTimeouts(long maxReplyTimeouts)

      Deprecated.
      Sets the maximum number message replies that can timeout in a healthy member.
      See Also:
        `getMaxReplyTimeouts()`

    - #### getMaxRetransmissionRatio

          double getMaxRetransmissionRatio()

      Deprecated.
      Returns the maximum ratio of multicast retransmissions / total multicast messages. Retransmissions are requestor-specific (i.e., unicast), so a single lost message may result in multiple retransmissions.

      A high retransmission ratio may indicate poor network conditions requiring reduced flow-control settings, a udp-fragment-size setting that is too high.

      See Also:
        `DEFAULT_MAX_RETRANSMISSION_RATIO`

    - #### setMaxRetransmissionRatio

          void setMaxRetransmissionRatio(double ratio)

      Deprecated.
      Sets the maximum ratio of multicast retransmissions / total multicast messages.
      See Also:
        `getMaxRetransmissionRatio()`
