Hi,
Concurrent sessions means the number of connections n the connection table at the same time on the ASA.
You can check the current amount and the maximum amount that has been active at the same time (since last reload for example) with the following command
show conn count
If the devices maximum connection amount is reached then any new connections are prevented from forming through the ASA
Hope this helps

Hi,
As I said, you can use the command
show conn count
This will list the amount of connections in the ASAs connection table at the time you issue the command. It will also tell what has been the maximum amount of connections on the ASA during the time its been up since last reboot.
Example from one firewall
ASA# sh conn count
11036 in use, 46990 most used

Hi,
Well I only deal with Cisco firewalls so I cant really help you with other vendors devices.
I would imagine that they would also have a way to show the same information than Cisco firewalls. I also would imagine that you shouldnt need to count anything like this with any formula, the device should show the information to you.
On the ASA there is also the following command
show local-host
This shows more information on connections through the firewall.
