This task describes how to trace the repository
  caches.
    - 
        To output detailed Ehcache usage information, set the following
        logging category to DEBUG:
        
org.alfresco.repo.cache.EhCacheTracerJob
 - 
        To target specific caches, you can append the cache name or package, for example:
        
org.alfresco.repo.cache.EhCacheTracerJob.org.SkyVault
 - Open to the <configRoot>\alfresco\scheduled-jobs-context.xml file.
 - 
        Locate the following bean:
        
ehCacheTracerJob
Override this bean to change the trigger schedule.
 - 
        Uncomment the scheduler property to activate the trigger.
        
When ehCacheTracerJob is triggered, the job will collect detailed cache usage statistics and output them to the log/console, depending on how logging has been configured for the server.
 - 
        To ensure that caches use statistics, set the statistics property for all caches.
        
statistics="true"
Use the cluster cache sample file or copy the default cache configuration file into the <extensions> directory.
