Enhanced Clusters: Failure Detection Properties
The following configuration properties (listed in Table 17–12) specify the parameters for the exchange of
heartbeat and status information within an enhanced cluster:
the host name (or IP address) for the heartbeat connection
the port number for the heartbeat connection service.
the interval, in seconds, at which heartbeat packets are transmitted.
the number of missed heartbeat intervals after which a broker is considered
suspect of failure.
the interval, in seconds, at which to monitor a suspect broker’s state
information to determine whether it has failed.
the number of elapsed monitor intervals after which a suspect broker is considered
to have failed.
Smaller values for these heartbeat and monitoring intervals will result
in quicker reaction to broker failure, but at the cost of reduced performance
and increased likelihood of false suspicions and erroneous failure detection.
