Regarding implementation of default code for ASSET Report Geeration
Need the code where the Logic for generating the "DOWNLOAD Count" in ASSET Download Report is implemented/maintained in AEM 6.5
AEM OOTB Asset Downloaded report can be generated only if following OSGi config is enabled.
- From the web console ([server name]:[port name]/system/console/configMgr), open the Day CQ DAM Event Recorder configuration:
- Select the Asset Downloaded (DOWNLOADED) option in Event Types if not already selected.
- Select “Enables this service”. Save the configuration.
This will make sure when user download the assets it is captured as an activity under that user.
