Pay attention to units of time on y-axis!
(s) seconds, (m) miliseconds, (u) microseconds - Something could appear to have a wild standard deviation, but the scale could be micro-seconds -- which is pretty tiny!How to read these charts
The title of the chart is the target being probed. Each line on the x-axis is a different remote probe pinging the target. There could be one, there could be multiple.The middle colored solid line is the median round-trip-time of a set of pings (usually 20). The color is the amount of packet loss encountered. The grey bands above/below (the "smoke") the solid line is the amount of variation between individual probes.
An ideal case is a solid, flat green line with little to no "smoke" which indicates a very consistent response. Red/purple indicates packet loss and lots of smoke indicates variation, both of which could indicate congestion on a path or problems.
