Bandwidth usage of EACH protocol (Windows server, linux server, Cisco routers and firewalls)

[Gotzon Astondoa]

Hi:

    I installed Nagios without problems, and it works fine. Great software!.
    I have it checking some services in some servers like: ftp, http,...
(using check_ftp, check_http...).

    But now, i need to check the bandwidth usage of EACH of these protocols.
    I was thinking to use nrpe and nrpe_nt to do it, but i can`t find
scripts that can do it. I need also do it with Cisco routers and firewalls.
    I find scripts that analyzes /proc/net/dev, but it is not enough for me.
    I know that  i'm asking for too much, but i'm lost (i don´t know nothing
about TCP/UDP analysis).

    Can somebody tell me a link or similar that can help me? (It is not
necessary that the script creates graphics nor nothing -i will do it-).

Thanks everybody in advance.
