Most Blocked Log Events could not be found

sometimes if there are multiple virtual server having "Log all requests" assigned, you might be missing the other logs like "blocked ones" because F5 now is actually logging each and every single request coming to those virtual server.

If this is the case, consider removing these profiles, and add "log illegal requests only" and if the issue still persists, try killing logging process, by running the below commands and test again:

pkill -f pabnagd

pkill -f asmlogd

pkill -f asm_config_server
