long	getLongTransactionTimeDumpThreshold() Returns threshold timeout in milliseconds for long transactions, if transaction exceeds it, it will be dumped in log with information about how much time did it spent in system time (time while aquiring locks, preparing, commiting, etc.)
double	getTransactionTimeDumpSamplesCoefficient() Returns the coefficient for samples of completed transactions that will be dumped in log.
int	getTransactionTimeDumpSamplesPerSecondLimit() Returns the limit of samples of completed transactions that will be dumped in log per second, if getTransactionTimeDumpSamplesCoefficient() is above 0.0.
boolean	getTxOwnerDumpRequestsAllowed() Shows if dump requests from local node to near node are allowed, when long running transaction is found.
long	getTxTimeoutOnPartitionMapExchange() Gets transaction timeout on partition map exchange.
