How to identify long live session(s) ?

L4 Transporter



I am trying to identify those long live sessions on my firewall,  I mean those session(s) that never ended for weeks at a time.


This is what I found out so far.


1.  I can't export the whole session log to perform offline analysis,

2,  I did not find anything related to session start time as filter under show session all filter.

3.  ACC will only record when a session is closed, I don't believe ACC will show that session data (session #, packets used, bytes used) until the session is ended.


Any suggestion?  


Thanks in advanced,

I think session table shows up to 1024 sessions at once.

If you don't have too many sessions then you could export from cli.

show session all start-at 1

show session all start-at 1025



By the way ACC data comes directly from dataplane and it does not matter if sec policy has "log at session start" and "log at session end" checked - ACC still shows everything. ACC is not real time - it has 15 min delay.

I thought about that, but the firewall have about 1 million active sessions  +/-  250k at any given time.    I was trying to look up how does ACC work, do you have a link to a techdoc?   For sure,  I am seeing long live session does not show up on ACC until the session is closed.



How about using custom report?

If you select 'traffic log (detailed log, not summary database), you can use one column named 'elapsed time (sec)'.


In this case all security policies should have "log at session start" that is not default.

It is nice option but writes a lot more log and log retention period is shorter.

I will need to try the custom report.   Thanks for the tips.

How about using the XML API calls on the firewall and filtering by min-age?
