From CLI (bash), run 'tail -f /var/log/ltm'&nbsp;
From CLI (tmsh), first do 'run util bash', then run the aforementioned tail command&nbsp;
This will show you real-time logs happening in LTM&nbsp;

the ltm log with certainly show you something, mainly things reported by the LTM module.&nbsp;
but it wont show you anything about traffic, not sure what you exactly expect to see, can you give some more details on that?&nbsp;

tcpdump will give you visibility into the traffic.

tcpdump gives you full visibility indeed, if you need to just checks if traffic is passed you could look at the statistics for the virtual server and pool member.
