Sorry for the truncated message; it was 4 am and I fell asleep at the
keyboard. To finish off properly:
What the results showed was that there were some systems that
pretty much never were detected as going down, but that at least
a third of the systems did not answer at some point during the day,
even though the systems and network were up for the entire time.
Some systems were more prone to disappearing pings than others were.
This was on a local LAN that I had complete control of -- and if pings
periodically fail "for no good reason" on systems on a local LAN, then
using ping to monitor remote systems is much *much* more likely to
be generate spurious down-reports.
If you are using Windows, then you might want to experiment with
Look@Lan and see how it goes for you.
