Ping Plotter?

I've been having ongoing issues with internet for quite some time. I was just informed by a tech support that "a ping plotter has been placed on my line to monitor".

What is a ping plotter?

How accurate and effective is it?

• How likely is it that it will detect the issues im dealing with, including: packet loss, jitter, t3 time outs, and randomly fluctuating upload speeds (1-35mbps)
