We have had our DLP Enforce console up and running for over two years. The events listed under System ... Servers and Detectors ... Events just keeps adding events and there is no way to delete them. We can delete old incidents, endpoint agents no longer connecting to the console, and server logs collected for expample but we cannot clean the server events up and ours is up there at over 170,000.
There should be a feature to allow you to query by date and then remove old entries listd in here. I really do not like the idea of premium disk space wasted on old logging items no longer needed.
