HOWTO - mattcasters/kettle-neo4j-logging GitHub Wiki
To make all your transformations and jobs log their execution results to Neo4j, install this plugin. Make sure to have a "Neo4j Connection" metastore object in the Neo4j namespace defined. To easily do that, install the Neo4j Output plugin and create a Neo4j Connection in one of the Neo4j step dialogs.
To enable the logging, set the name of the connection to use in variable : NEO4J_LOGGING_CONNECTION You can set it in the kettle.properties file for convenience.
