That's the value that was returned by Fping during one or more (creating the varying shades of gray) of the 20 Fping probes in that 5 minute interval.

Thank you for the response Vinny.  I see what you mean, but I still don't understand where the 90m (light grey) values on the graph come from when I never receive anything more than 76ms ping responses.

Perhaps the graphs aren't scaling properly?

I could be mistaken, but I think the numbers represent the average, maximum average and minimum average on the graph across all samples in that time period rather than the maximum single rtt of any sample.

Hi Smokeping-Users / Community

I have a quick question hopefully --

http://tinypic.com/view.php?pic=21doi9g&s=5

The grey graphs represent the Max Round trip time correct?  How come the data provided just below the graph doesn't reflect what I am seeing on the y-axis?

I never see 100ms spikes but the graph would indicate this.

Any recommendations on getting my graph tuned to be more accurate?

--------------------------

+ charts

menu = Charts
title = The most interesting destinations

++ stddev
sorter = StdDev(entries=>4)
title = Top Standard Deviation
menu = Std Deviation
format = Standard Deviation %f

++ max
sorter = Max(entries=>5)
title = Top Max Roundtrip Time
menu = by Max
format = Max Roundtrip Time %f seconds

++ loss
sorter = Loss(entries=>5)
title = Top Packet Loss
menu = Loss
format = Packets Lost %f

++ median
sorter = Median(entries=>5)
title = Top Median Roundtrip Time
menu = by Median
format = Median RTT %f seconds

+ overview

width = 600
height = 50
range = 10h

+ detail

width = 600
height = 300
unison_tolerance = 4
logarithmic = no

"Last 3 Hours"    3h
"Last 30 Hours"   30h
"Last 10 Days"    10d
"Last 400 Days"   400d
