More Information


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.
