To obtain a more detailed information about consistency checks in the logs, make sure you also have the appropriate setting in the log4j configuration file, for example:
<Logger name="org.apache.jackrabbit" level="info">
<AppenderRef ref="console"/>
</Logger>
Together with a consistency check for a workspace enabled (see below) for example, the logger would print the following into the log file:
INFO org.apache.jackrabbit.core.RepositoryImpl 16.10.2018 09:48:32 -- initializing workspace 'website'... INFO org.apache.jackrabbit.core.fs.local.LocalFileSystem 16.10.2018 09:48:32 -- LocalFileSystem initialized at path /m/mgnl-bundles/apache-tomcat/webapps/magnoliaAuthor/repositories/magnolia/workspaces/website/default INFO org.apache.jackrabbit.core.persistence.bundle.ConsistencyCheckerImpl 16.10.2018 09:48:32 -- website: checked 601 bundles. INFO org.apache.jackrabbit.core.query.lucene.SearchIndex 16.10.2018 09:48:32 -- Index initialized: /m/mgnl-bundles/apache-tomcat/webapps/magnoliaAuthor/repositories/magnolia/workspaces/website/index Version: 3 INFO org.apache.jackrabbit.core.RepositoryImpl 16.10.2018 09:48:32 -- workspace 'website' initialized
See especially line 3 in the result log.
