F5 - How to get histroical statistical data from LTM?

There are TCP transmission issues in LTM.  I am seeing lot of retransmissions happening when load is increasing and number users visits are growing in exponential.  To confirm this I need to go back look at the trend. How can I get historical users connection counts ?

If you have APM, then its reporting will be useful but from LTM, it is not a straight off the shelf equivalent to user identity as it is ore client ip address. And if you have not configure any logging specific for troubleshooting the symptom, it is not easy to sieve out though you can try the tmsh show sys connection which is the basic starting point. But you'll see all the connections unless you go more specific. Do see this which you can limit the output to only things that match certain ip  in mind or knows off for isolating the issue.

another means for troubleshooting to be more targeted can be via health monitors log as a mean since you can target specific server and assign particular pool, pool member, or node. See this for specific configuration, and if need to drill deeper, this will be useful capturing internal TMM information with tcpdump. For info, when the default number of retransmissions is exceeded, TMM resets the TCP connection to avoid resource starvation during a potential denial of service attack.

separately, I am thinking for retransmission can be troubleshooted targeting for TCP RST packets. For example in this, you can consider to configure the LTM to log the reasons for generating the TCP RST packets to the /var/log/ltm log file
