First: If I have an ASA 5500(05 or 10), how can i view the bandwidth usage per internal IP? For example, lets say I have a T1 and for a whole day the inbound traffic pegs the link. I know the ASA can show me how much bandwidth is being used, but the top 10 sources/dest doesnt always even show internal addresses at all. I am willing to do this in the CLI as well, but I NEED to do this and should be a simple function for a firewall of this caliber.
Second: on the monitoring/VPN section on the ASDM, where the VPN sessions are listed. Is there a way to autorefresh that section, or is the only way to get an updated view of your current VPN sessions to click refresh?
The "interface graph" option on the monitoring ASDM homepage provides real-time monitoring of bandwidth usage for each interface on the security appliance. Bandwidth usage is displayed for incoming and outgoing communications. Users can view packet rates, counts, and errors; bit, byte, and collision counts; and more. I think only "Refresh button" is available on VPN statistics panel.
There doesn't seem to be a way to do this via the GUI unless it's hiding very well. I was hoping another poster would answer your question affirmatively.
Even in the CLI there aren't many options. You can explore "show local-host" and its parameters but this isn't a good solution since the connections are ephemeral. A test to show this is "show local-host " while you visit a website. You'll see the individual connections come and go with no cumulative byte-counts left behind.
