iRule to log RST timeouts?

Hi there, we're trying to log RST for a single vs/pool ideally through an irule, but I've only found a way to do it through tmsh which enables it for the whole device, therefore filling it up with logs pretty quickly.

 

Is there a way to enable "modify /sys db tm.rstcause.log value enable" for just a vip/pool or some way to do it through an irule?

 

I've read somewhere else that irules can't read raw tcp which is why it couldn't be done.

 

Thanks!!

  • Can't you grep the logs for the specific VS/Pool ? Which particular event are you trying to capture by logging RST ? I mean, among the many reasons for which the F5 will send a RST, are you specifically interested in any or all ?
