Pandikumar_MuruIs it possble through any commends or Irule ?
kunjanIn real time you can use tcpdump if you have access to the cli, something like 'tcpdump -ni 0.0 host vip'

this irule will do it, I hope you don't have a lot of traffic on the VIP! are you sure the every 5 second hit on the proxies isn't the F5 health checks from the primary and standby?
Log-all tcp traffic to a vip,
when CLIENT_ACCEPTED {
set vip [IP::local_addr]:[TCP::local_port] }when SERVER_CONNECTED {
set client "[IP::client_addr]:[TCP::client_port]" set node "[IP::server_addr]:[TCP::server_port]" }when CLIENT_CLOSED {
log connection info log local0.err "Client $client -> VIP: $vip -> Node: $node"
}- Pandikumar_MuruI am not aware of Helth check, I have reviewed the config its enabled TCP monitor, 5 sec. May Helath check will give a hits, How ever if we enable log we will get some Idea, Am i right ?

the irule will only catch traffic hitting the vip. the health checks will not hit the vip so they would not be logged, Use TCP dump and you will get your answer.
