TransactionLogUtil Script

Purpose

The Appian engines synchronously store write transactions in the Kafka component of the Internal Messaging Service as they are applied. For troubleshooting purposes it is sometimes useful to be able to look at the contents of the transaction log for an engine to see how many transactions were applied in a given time period, what types of transactions are flowing through the system, or what parameters were used in a particularly slow transaction. The transactionLogUtil script outputs the contents of the transaction log, including the timestamp, id, method name, executing user, size, and duration of each transaction.

Run this script when directed to do so by Appian Support as part of troubleshooting.

Location

<APPIAN_HOME>/services/bin/transactionLogUtil.sh (.bat)

Options

Short Name	Long Name	Required	Meaning
-h	--help	No	Show usage information
-s	--start	No	Starting date or transaction id
-e	--end	No	Ending date or transaction id
-l	--limit	No	Maximum number of transactions to process
-p	--print	No	Print transactions

The --print option requires a format of either detail, summary, or hex. The default value is summary.

Running without the --start, --limit, and --end parameters will result in all transactions for the specified service being printed out.

Usage

The transactionLogUtil script takes as a parameter the name of a service for which to export transactions. One of: analytics00…analytics31, channels, content, download-stats, execution00…execution31, forums, groups, notifications, notifications-email, portal, process-design.
