public TransactionMetricsSnapshot()

Required by Externalizable.

TransactionMetricsSnapshot

public TransactionMetricsSnapshot(TransactionMetricsAdapter adapter)

Parameters:

adapter - Transaction metrics adapter.

Method Detail

commitTime

public long commitTime()

Gets last time transaction was committed.

Specified by:

commitTime in interface TransactionMetrics

Returns:

Last commit time.

rollbackTime

public long rollbackTime()

Gets last time transaction was rollback.

Specified by:

rollbackTime in interface TransactionMetrics

Returns:

Last rollback time.

txCommits

public int txCommits()

Gets total number of transaction commits.

Specified by:

txCommits in interface TransactionMetrics

Returns:

Number of transaction commits.

txRollbacks

public int txRollbacks()

Gets total number of transaction rollbacks.

Specified by:

txRollbacks in interface TransactionMetrics

Returns:

Number of transaction rollbacks.

getAllOwnerTransactions

public Map<String,String> getAllOwnerTransactions()

Gets a map of all transactions for which the local node is the originating node.

Specified by:

getAllOwnerTransactions in interface TransactionMetrics

Returns:

Map of local node owning transactions.

getLongRunningOwnerTransactions

public Map<String,String> getLongRunningOwnerTransactions(int duration)

Gets a map of all transactions for which the local node is the originating node and which duration exceeds the given duration.

Specified by:

getLongRunningOwnerTransactions in interface TransactionMetrics

Parameters:

duration - Transaction duration.

Returns:

Map of local node owning transactions which duration is longer than duration.

getTransactionsCommittedNumber

public long getTransactionsCommittedNumber()

The number of transactions which were committed on the local node.

Specified by:

getTransactionsCommittedNumber in interface TransactionMetrics

Returns:

The number of transactions which were committed on the local node.

getTransactionsRolledBackNumber

public long getTransactionsRolledBackNumber()

The number of transactions which were rolled back on the local node.

Specified by:

getTransactionsRolledBackNumber in interface TransactionMetrics

Returns:

The number of transactions which were rolled back on the local node.
