[Xymon] Ping tests showing different levels percision

[Michael Beatty]

I just noticed that different hosts are displaying ping results with 
very different levels precision.  On 3 of the hosts, the test seems to 
be retuning results that are much more precise than on the other 3.  If 
you look at the graphs and data, data points are frequently changing up 
and down with an active graph.  On the other 3, the data is basically a 
flat line, almost always showing the same value.

The one thing that that I can see that the more precise graphs are 
showing is that all of those systems have ping results measured in 
milisecods and are on the same network, where as the 3 that are not as 
precise are not.  One of them is my local system itself pinging itself 
and its data points are measured microseconds.  The other two are over a 
satellite and their pings are between 1 and 3 seconds.  For example, one 
of the hosts is almost always showing 40 ms where as another is changing 
with ever report between about 1000 ms and 3000 ms.

Is this normal, is there some kind of normalization that happens on 
hosts whos tests don't change much in value?
