Controlling logging
Neo4j embedded provides logging via its own org.neo4j.logging.Log
layer and does not natively use any existing Java logging framework.
All logging events produced by Neo4j have a name, a level, and a message.
The name is а fully qualified class name (FQCN).
Level Name | Description |
---|---|
|
For serious errors that are almost always fatal. |
|
For events that are serious, but not fatal. |
|
Informational events. |
|
Debugging events. |
To enable logging, an implementation of org.neo4j.logging.LogProvider
must be provided to the org.neo4j.dbms.api.DatabaseManagementServiceBuilder
, as follows:
LogProvider logProvider = new MyCustomLogProvider( output );
managementService = new DatabaseManagementServiceBuilder( databaseDirectory ).setUserLogProvider( logProvider ).build();
