Here is my situation: We have a contract with an ISP that is providing very bad service and internet speed goes up and down intermitently so it is hard to prove it to them. I have a Cisco ASA 5510 that tells me the bandwidth that we are using and sometimes I see we're not using most of our bandwidth (2 T1). But when I do a speedtest (Speakeasy) - I see that the speed is extremely slow.
I was wondering if there is a tool, free or not that would record the bandwidth that is being used from Cisco ASA (or a Cisco router 2600 series) vs the external speed at the time. Sampling the bandwidth at regular 1, 2 or 5 minutes intervals would be ideal and record the information somewhere.
We've talked to ISP (which is Cornerstone - http://www.cornerstonetelephone.com) but they would not admit that there is something wrong. We have tripple checked our devices and they are fine. I need somehow to prove to them - what a weird ISP. I can't wait to get out of the contract from them. I have heard other companies that are with them that had problems. Two were lucky as their contract expired.
Please help - any suggestion is very highly appreciated.
