Constructor Detail

TransactionService

public TransactionService()

TransactionService

public TransactionService(int numMaintenanceThreads,
                          long initialDelay,
                          long delay,
                          java.util.concurrent.TimeUnit timeUnit)

Method Detail

processQueue

public void processQueue()

The only reason this was pulled out of the runnable is for testing purposes. Otherwise, do not call it directly.

transactionStarted

public void transactionStarted(Transaction transaction)

transactionFinished

public void transactionFinished(TransactionData transactionData,
                                TransactionStats transactionStats)

A transaction completed "normally". This means the Agent completed its processing normally; the application processing captured by the transaction may have resulted in an error.

transactionCancelled

public void transactionCancelled(Transaction transaction)

The transaction is completing abruptly, either because the agent encountered an internal error or because the transaction's sole activity was reparented to another transaction as a result of token linking. Cancelled transactions are not reported to New Relic and they do not generate transaction events.
