We have ISP that provides us with a shoddy service. It usually works, but there are times when it works really bad, drops connections and gets awfully slow. Sadly, our contract doesn't have SLA clause that we can invoke in this instance.
How can I best measure both inbound latency outbound latency and packet loss? These are specific parameters that I think would tell me if we had an outage (even a short one for less than a minute), if there were any delays due to congested link, and so on. Having nice, informative graphs would be a plus.
