What is the most effective method for searching for usage of a hostname or IP address across our entire PA environment? The goal is to be able to identify and delete objects and rules that have been created in our firewalls that correspond to hosts/IPs that have been retired from our environment. We get notified of those retirements, so I'd like to be able to easily scan our PA environment to determine if they were used anywhere. If they were, we'll go in and clean up any reference to them. Our environment consists of Panorama and several firewalls. General Enterprise firewall settings come from Panorama to all firewalls, but local admins can add rules to their specific firewalls. Thanks
