ASA Bandwidth logging

[markbialik]

We're in a semi-managed environment, and I don't have an internet-facing router. Normally, I would grab bandwidth usage stats from the WAN port of a router via SNMP/MRTG. Unfortunately, the router is owned by the hosting company, and we rely on their usage graphs for billing purposes.

Recently, according to them, our bandwidth usage has been increasing. I don't have a reason not to believe them, I just want to keep them honest.

I have an internet-facing ASA. Is there a way to continuously monitor the inbound & outbound traffic counts on the ASA's external interface, save them somewhere, and analyze/graph the results? I want to compare the data to the graphs provided by our hosting company.

Thanks for any assistance.

You could use mrtg with the ASA. Also you can graph directly from the ASDM.

prtg is good too.

i just set it up for a client last week. and it's free for upto a couple of devices. no messy config files like mrtg.
