Troubleshooting and logs

a very valid question, but also something which can get more complicated then showing a few steps. if at all possible look if you or your company has people around who have already done this and can explain / do it together. an alternative could be a online training for using F5 BIG-IP.

for what is available online this is a nice introduction with examples and some step by step parts: https://clouddocs.f5.com/training/community/adc/html/class1/module1/module1.html 

as for the logging part, out of the box the BIG-IP won't log traffic or show you how it flows through it. it might log some stuff in the /var/log/ltm log for this, but mainly bigger issues (nodes unreachable).

if you want to see the flow you either have to do a tcpdump or create logging with iRules, this article gives a nice example: https://my.f5.com/manage/s/article/K41861214
