WSS_Logging DB SharePoint 2010 ( Usage Reporting)

SharePoint 2013 is out  but i still get the queries regarding the usage reporting capability of SP 2010.

Some pointers below.

• The data displayed by SharePoint Web Analytics is pulled from "WSS_Logging" database. It aggregates all of the raw logging data accumulated in the text files under the 14 hive and imports it into logging database. 

• Web Analytics Service Retention Policy 

          To persist the usage data in WSS_Logging for longer time you can change the retention policy
           by  changing the settings in central administration

          Central Administration - > Application Management - > Manage Servcie Application
          - >Select Web Analytics Service ->Click "Properties" in ribbon ->Change Data Retention
          Period up  to 25 months.

• The data import from Logs files to Database is performed by Timer Job " Microsoft SharePoint Foundation Usage Data Import"

         You can set the frequency of timer job depending on load on your server.
