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.
