Attribute Name Access Type Description Attribute Value
TotalAverageSmoothedRetransmissionTime R double (no description)
-1.0    
XmitTableSize R int (no description)
3    
RetransmitTimeouts RW long[] Timeout before requesting retransmissions. Default is 600, 1200, 2400, 4800
    
DiscardDeliveredMsgs RW boolean Should messages delivered to application be discarded
TrueFalse    
MaxMsgBatchSize RW int Max number of messages to be removed from a NakReceiverWindow. This property might get removed anytime, so don't use it !
    
UseStatsForRetransmission RW boolean Use statistics gathered from actual retransmission times to compute new retransmission times. Default is false
TrueFalse    
XmitReqsSent R long Number of retransmit requests sent
0    
ExponentialBackoff RW long The first value (in milliseconds) to use in the exponential backoff. Enabled if greater than 0. Default is 0
    
UseMcastXmit RW boolean Retransmit messages using multicast rather than unicast
TrueFalse    
EnableXmitTimeStats RW boolean If true, retransmissions stats will be captured. Default is false
TrueFalse    
XmitFromRandomMember RW boolean Ask a random member for retransmission of a missing message. Default is false
TrueFalse    
MissingMsgsReceived R long Number of missing messages received
0    
PrintStabilityHistoryOnFailedXmit RW boolean Should stability history be printed if we fail in retransmission. Default is false
TrueFalse    
AverageSmoothedLossRate R double (no description)
0.0    
XmitHistoryMaxSize RW int Size of retransmission history. Default is 50 entries
    
TotalAverageRetransmissionTime R double (no description)
-1.0    
Ergonomics RW boolean Enables ergonomics: dynamically find the best values for properties at runtime
TrueFalse    
MaxRebroadcastTimeout RW long Timeout to rebroadcast messages. Default is 2000 msec
    
LogNotFoundMsgs RW boolean If true, trashes warnings about retransmission messages not found in the xmit_table (used for testing)
TrueFalse    
XmitRspsReceived R long Number of retransmit responses received
0    
MaxXmitBufSize RW int If value is > 0, the retransmit buffer is bounded. If value <= 0 unbounded buffers are used. Default is 0
    
LogDiscardMsgs RW boolean discards warnings about promiscuous traffic
TrueFalse    
Dynamic MBean Description R java.lang.String MBean description
Reliable transmission multipoint FIFO protocol    
AverageLossRate R double (no description)
0.0    
Name R java.lang.String Give the protocol a different name if needed so we can have multiple instances of it in the same stack
NAKACK    
XmitRspsSent R long Number of retransmit responses sent
0    
Level RW java.lang.String Sets the logger level (see javadocs)
    
Id RW short Give the protocol a different ID if needed so we can have multiple instances of it in the same stack
    
UseRangeBasedRetransmitter RW boolean Whether to use the old retransmitter which retransmits individual messages or the new one which uses ranges of retransmitted messages. Default is true. Note that this property will be removed in 3.0; it is only used to switch back to the old (and proven) retransmitter mechanism if issues occur
TrueFalse    
UseMcastXmitReq RW boolean Use a multicast to request retransmission of missing messages. Default is false
TrueFalse    
Stats RW boolean Determines whether to collect statistics (and expose them via JMX). Default is true
TrueFalse    
XmitReqsReceived R long Number of retransmit requests received
0    
PendingRetransmissionRequests R int Total number of missing messages
0    
GcLag RW int Garbage collection lag
