This is the downtime that I measure for my @Home cable modem system.
It works by sending 1440
ping messages from my home system to their mail server, with a minute in between; this takes a day in total.
After one day, a report looks a bit like this:ping -n -c 1440 -i 60 -q mail.home.nl
I have a little script that takes this information apart, and splits it over a number of files which list these numbers. These lists are then used to demonstrate the uptime of @Home (from my system). I resynchronise this command with the realtime clock every night at midnight.PING mail.home.nl (184.108.40.206) from 220.127.116.11 : 56(84) bytes of data. --- mail.home.nl ping statistics --- 1440 packets transmitted, 1234 packets received, 14% packet loss round-trip min/avg/max/mdev = 29.347/33.670/39.318/2.624 ms
