Table 5–2 MONITOR GROUP Fields
Field	Meaning
krid	Key range (partition) identifier.
state	Partition state.
txn cnt	Number of transactions executed for this partition.
srv cnt	Number of servers active for this partition.
srv act	Number servers that are currently busy processing txns for this sample.

The following fields track the progress of a transaction through the states: vote requested, voted, acknowledged.

vreq	Number of transactions that are waiting for the server to vote.
vote	Number of transactions that have been voted on by the server but not
	committed by RTR.
ack	Number of transactions that have been committed but have not been
	acknowledged by the server. Acknowledgment occurs on a subsequent
	rtr_receive_message( ) call by the server processing this transaction
	to get a message for a new transaction.
/csn	Number of transactions which have been grouped under the same ``commit
	sequence number'' (CSN). This grouping determines the ordering of
	transactions submitted to a secondary shadow server.
txn/sec	The average rate of transaction starts per second for this partition.
txn/csn	average number of transactions which have been grouped under the same
	commit sequence number (CSN) since this partition became active. This
	average is computed as the quotient of the txn cnt column and the total
	number of CSN's.
