Software for monitoring Internet connection Speed/Quality

Hi, Looking for some software to monitor an Internet connection for speed and quality over time. Doesn't need to be free but don't want to spend thousands either.

Have a customer with a [censored] fiber (!) connection but the ISP (small, local) says it never drops a ping. The performance is seriously bad right at the NID, up to 5% packet loss with a simple ping test, with speeds all over the board. Would like to monitor, test, and log over 30 days and provide a report. Such a tool would be a great thing to have in my arsenal when a client wants a VOIP survey.

The familiar pattern (and North Americanisms) is now discernible. Thanks for the spam! (Reported)
