NetIQ Identity Manager 4.8 Report DB rapidly growing with SLM data

Hi

Have a NetIQ Identity Manager 4.8 reporting setup (Using PortgreSQL), that receive data (eDir event) from Sentinel Log Management (SLM). The data from the SLM is filling up the Reporting DB quickly a grow from 5 GB to 480GB over 2½ month.

In the "public" schema there is several tables called "sentinal_events_yyyy_mm_dd (sentinel_events_2020_08_24)

Is there a way to clean up this "Sentinel Log Management " data in the reporting DB which is more then 1 month old??

Best regards

Michael
