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.

Field Detail

DEFAULT_MAX_VM_PROCESS_SIZE

static final long DEFAULT_MAX_VM_PROCESS_SIZE

Constant Field Values

DEFAULT_MAX_MESSAGE_QUEUE_SIZE

static final long DEFAULT_MAX_MESSAGE_QUEUE_SIZE

Deprecated.

The default maximum number of enqueued incoming or outgoing messages that a healthy member of a distributed system can have. The default value is 1000.

Constant Field Values

DEFAULT_MAX_REPLY_TIMEOUTS

static final long DEFAULT_MAX_REPLY_TIMEOUTS

Deprecated.

The default maximum number of message reply timeouts that can occur in a given health monitoring interval. The default value is zero.

Constant Field Values

DEFAULT_MAX_RETRANSMISSION_RATIO

static final double DEFAULT_MAX_RETRANSMISSION_RATIO

Deprecated.

The default maximum multicast retransmission ratio. The default value is 0.20 (twenty percent of messages retransmitted)

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.
