Each 30 minutes the Collection Site server pings a set of
Remote Site hosts with
11 pings of 100 bytes each, followed by ten pings of 1000 bytes.
The minimum separation
between pings is 1 second and the timeout is 20 secs.
The first ping is thrown away (it is presumed to be slow since
it is priming the name caches etc.). The minimum / average / maximum and
packet loss for
each set of 10 pings is recorded. This table shows the results of the
most recent set of measurements for each Remote Site. It also
provides hot links for each site to plots of the daily average
ping response times and packet losses for the last 180 days, and to the
ping measurements so far today.
