Jason, the default for mrtg-ping-probe is to send 10 pings, then you could see values 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 % returned from mrtg-ping-probe. The question then is does mrtg average these values over a period of time ... Look into the mrtg log file, mine e.g. looks like this: grep -v " 0 0 0 0" rubycon.loss.log | head 1047055815 0 0 1047044400 0 0 10 10 1047044100 10 10 10 10 1047043800 9 9 10 10 1047039900 0 0 10 10 1047039600 9 9 10 10 1047032700 0 0 10 10 1047032400 9 9 10 10 1047029400 0 0 10 10 1047029100 9 9 10 10 The format of the logfile is documented here: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/logfile.html note that colume 2 and 3 are the average since the last measurement, hence you get numbers we initially did not expect to see. Include this option for your target: WithPeak[rubycon.loss]: ymwd to see the peak values in addition to the averaged values Hope this helps --pwo -- Peter W.
