[Xymon] Unexpected times on "Connection Times" graph

[Galen Johnson]

Actually, you may notice that the ping time is the "total" time of the
pings.  The avg time is probably what Xymon should be keying on.  I'm not
where I can check but I think Xymon does a count of 8 or 10 pings so the
value you see is likely the sum of all those...in your posting:

--- palazzo.REDACTED.com <http://palazzo.redacted.com/> ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time *4003ms*
rtt min/avg/max/mdev = 0.572/*0.645*/0.890/0.126 ms

the highlighted value is more in line with what you are seeing when you run
it by hand.
