I have an ASA5510 and an 1841. Each of those devices sit at different clients, so they have no relationship.
What I thin is happening is that the ASA, as well as the 1841, the customers might be exceeding they router capacity. So I'd like to get a tool that can tell you that your device is indeed using 80 or 90% of CPU time. If this tool can present the results in graphics, then it will even be better.
Is there a free tool that can read router's or firewall's performance in a given period of time (for example in a 24 hour period or in a week's period)
thanks in advanced
