Export 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 export script outputs the contents of the transaction log in a machine-readable format for analysis by Appian Support.

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

Location

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