Log message for exceeding the bandwidth limit (bwc)

Hi,

I have created a static bandwidth controller and attached it to a specific route domain. 

When I was creating more traffic than allowed I have seen that the traffic was capped. 
So far so so good.

But unfortunately i  didn't get any log messages  for exceeding the limit. 

Should there be log messages for this?

If yes, what can i do to see them ? Should these messages be in the ltm logs?

Thanks  a lot,

Heiko
