i'm using ZM 1.22.2 for a few months now for the company i work for. I use the following filter:
The disk usage is at ~70% and still growing ~1% each day. The event button just shows all events in this time space (30 days). But ZM still eats up all my hdd space!IF date <= -31 days
OR disk usage => 80 %
then automatically delete all hits
