What is the best way to measure the current throughput on an ASA? I'm guessing you can add all the bytes/sec up from a show interface but i am hoping there is a better way. I am running 8.x
The show traffic command lists the number of packets and bytes moving through through each interface since the last show traffic command was entered or since the security appliance came online. The number of seconds is the duration the security appliance has been online since the last reboot, unless the clear traffic command was entered since the last reboot. If this is the case, then the number of seconds is the duration since that command was entered. For the ASA 5550 adaptive security appliance, the show traffic command also shows the aggregated throughput per slot.
Also, another way could be to use netflow (8.2 +), and it can give you detailed throughput crossing the ASA.
