TCP Inactivity Timeout

We recently increased the TCP inactivity timeout on a vserver via the TCP profile. I'd like to validate that the timeout is set appropriately and see if there are any sessions still getting terminated by this timer. Are there any logs that would show this info?

 

 

Thank you!

    Thank you, this info is very helpful. What I'm not sure about though, is this showing me active connections only? What about historical connections, say in the last hour?

    Nope.

     

     

    The connection table is current connections. trying to keep historical info wouldn't scale very well for a busy site.

     

     

    If you want this level of info you need to write an iRule and log something everytime a connection is closed. The more sophisticated your iRule, the more info you'll get too... (And use more memory and CPU as well)
