You can enable or disable the display of the SSL categorization trend statistics by using the Network Security appliance Web UI or CLI:
When the SSL categorization trend feature is enabled on the Network Security appliance, the graphs of the collected traffic throughput statistics are displayed on the Dashboard of the Web UI. You can see which SSL traffic has been bypassed, whitelisted, uncategorized, or intercepted based on URL categories and category groups even when SSL interception is disabled on the appliance. When the SSL categorization trend feature is disabled on the Network Security appliance, the graphs of the collected traffic throughput statistics are not displayed. The feature is disabled by default and must be enabled.
