I'd suggest to check the MyF5 article - K16197: Reviewing BIG-IP log files
https://my.f5.com/manage/s/article/K16197It covers the log reviewing basis of various interfaces and includes tmsh examples/videos for time filtering. Thanks.

CirrusHey Imran, it depends exactly which type of logs you are looking for.
If you are logged in to the web console, you can go to Security > Event Logs.
However, because you are troubleshooting, it sounds like maybe you are needing the LTM logs (since that is where my troubleshooting steps usually go to).
If you log in to your box via SSH, you can type "tmsh" to switch to your virtual terminal. From here, type "show /sys log type" replacing 'type' with the type of log you are looking for. You can type "show /sys log all" to view the different types of logs. For instance you can use "show /sys log ltm" which for me has helped a lot.
From outside of tmsh, you can just cd to /var/log to see multiple log files. The equivalent of viewing the LTM log would be "tail /var/log/ltm"
Hope that helps!
