Unfortunately the ping solution is hard to monitor and to assess.
On the other hand I already installed Nagios but it is designed to probe

only one packet doesn't arrive to the destination the db get out of sync
and I am stuck with the same problem.
I am looking for something like a mrtg graphic that will signal eventual
Thank you for your time,
