Hi Everyone!
I'm trying to figure out how to create a widget, that will show the top ten servers that have a ping of above 100ms.
I can make the standard ping widget, but I don't see a way to limit the graph to those servers that have a high ping. Do I need to use the virtual datapoint?
Or, maybe I need clarification on what it means when I select top 10 on an average, or maxrtt datapoint.
Thanks!

EmployeeHey @Phillip,
As @Cole McDonald noted, you can use a virtual datapoint with the Ping datasource in something like the custom graph widget - here's the expression you would want to use:
if(lt(average,100),unkn,average)
Which says "If the average ping round trip time is less than 100ms, return an unknown value (so it doesn't get graphed,) otherwise return the actual value of the datapoint."
Hope that helps!
Cheers,
Kerry
Try taking a look at this dashboard that Kerry D created. It has two widgets by ping and port latency.

and yes? I don't quite recall how to have it return a NaN, but I have done it in the past, so I know it's possible. unkn() is a constant for it, that may have been how I did it... so: if(maxrtt>100,1,unkn()) ?

OK, I understood the first part. I'm not sure on the expression for the second part. I'm not familiar with the complex datapoint syntax for the expression. Should it look like if(maxrtt>100, 1, NaN)?
