Web Application Protector, App & API Protector List the evaluation hostnames for a configuration version. Evaluation mode for hostnames is only available for Web Application Protector and App & API Protector. Run hostnames in evaluation mode to see how your configuration settings protect traffic for that hostname before adding a hostname directly to a live configuration. Once you begin, the hostnames you evaluate start responding to traffic as if they are your current hostnames. However, instead of taking an action the evaluation hostnames log which action they would have taken if they were your actively protected hostnames and not a test.
