What network latency monitor has a latency log?

Hallo!
I have a network connection set up for me by a technician and I agree that it is working very well. What I would like to know is whether I can have a setup of Network latency monitor application to establish how stable the network connection is throughout. The application, once installed should be able to create logs of the connection details on a regular basis which I can go through later. Thanks a bunch.
