This will simply store 100-x (percentage success) in the RRD. Of course
this means you lose your history.<o:p></o:p></p>

have the option to do:<br>

This will allow you to keep your history and continue to store percentage loss,

<p class=MsoNormal><span lang=EN-NZ style='color:#1F497D'>Note that in both
cases, you’ll need to change your various labels for the axis and
legend. Also, note that routers2 will recognise the mrtg-ping-probe
plugin and may default to displaying the data as a floating bar, if
you’re graphing min/max RTT data. If this is unwanted, look at
using the <b>routers.cgi*GraphStyle[]:normal</b> directive.<o:p></o:p></span></p>
