hi,all: i check the NN metrics ,and find the "TransactionsSinceLastCheckpoint" is a negtive number, but why it will be a negtive number,after the last check point ,if no transaction happened ,the number should be zero, if transaction happened,it should be a positive number. why?
"TransactionsSinceLastCheckpoint" : -418,
"TransactionsSinceLastLogRoll" : 0,
"LastWrittenTransactionId" : 228383,
"LastCheckpointTime" : 1384763666158,
