I have a Cisco ASA 5510 which, by using the GUI, can give me a top IP list of senders and receivers during the last 24 hours. However I would like to automate a report every day written to a file (e.g. 2011-11-01_top10_senders.txt and _receivers.txt), so I can locate computers that sends/receives a lot of data over a period of e.g. 4 days.
I have done some scripting some years ago using rrdtool, but I wonder if anybody know a URL that have this mostly set up? RRDtool creates graphs and not lists like I seem to need now.
Any answer would greatly be appreciated.
