No Sample Requests are "found" in v12 ASM Traffic Learning

The logging profile determines if all requests or illegal requests only will appear in Security: Event Logs: Application: Requests. It does not control whether or not learning suggestions will appear on the Traffic Learning screen. If you are not seeing any learning suggestions, it may be because there aren't any violations. Troubleshoot by first verifying that you have selected the correct application language encoding for your security policy, then verify that traffic is actually passing from the client to the virtual server, then verify that you have assigned the correct security policy to the correct virtual server. Also, is it possible that the policy has already generated suggestions and they have either been accepted or ignored? If you send a request, do you see anything in /var/log/asm? The rule of thumb is that ASM is doing exactly what you told it to do...
