ASM Policy - How to collect information from tmsh

For your doubts I suggest first to check the '' learn F5'' that has free training (start with the "Getting Started" short courses) as when you know the technology then you will see if it is good for your needs, also for the ASM and the other modules that F5 has short operations guides:

From CLI you can't do a lot for the ASM module and this is why you use the GUI as this is the new way to go for many security devices like F5 (palo alto etc.). You can use the "ASM Audit Log in Security -> Application Security -> Policy -> Audit -> Logs" to see the changes made for each specific policy and revert to an older version (at one point it was called History menu).
