<p class=MsoNormal>Take a look at the man page for rrdgraph_data. That
describes how to use CDEF:<o:p></o:p></p>

</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>

<div>
<p class=MsoNormal> This command creates a new
set of data points (in memory only, not in<o:p></o:p></p>

<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>After using DEF to define the variables being pulled from
the various RRDs, you should be able to combine them with a math expression.
You would then use the CDEF vname in the graph LINE, AREA, etc.<o:p></o:p></p>

Munin, its possible to sum several rrd into one graph (ie : to display the

it’s possible to do this in XYmon too ? I saw the « Metrics
