Can a processing extension be used to track report use in CRS 2008?

Hi,

I am a consultant working with a client who is running a pre-V1 release of Crystal Reports Server 2008 which does not have auditing support. They want to find out which Crystal Reports in their CRS environment are used so they can identify the unused reports and clean them up. Is it possible for a processing extension to mimic the Auditing functionality by detecting and documenting Crystal Report scheduling, view on demand, and historical instance viewing requests, and writing the report name, folder path, user name, and timestamp to a database?

Any help on this would be much appreciated.

Regards,

Janice
