LTM Log Files

I need to be able to see tcp traffic between client and F5 and between F5 and pool memebers. Anybody knows how I can setup and view that? Thanks

by default, system log (e.g. /var/log/ltm) does not include application traffic. if you want to log application traffic, you can use irule.

e.g.

Log Http Tcp Udp To Syslogng

do yo mean packet? if yes, you can run tcpdump. tcpdump -nni 0.0 -s0 host x.x.x.x or host y.y.y.y x.x.x.x is client ip y.y.y.y is pool member ip

(more tcpdump info) - https://support.f5.com/kb/en-us/solutions/public/0000/400/sol411.html There is also the command "tmsh show sys connection" which will show you current connection details
