custom graphing. With SPLITNCV you have a separate rrd for each DS so at least
you don't loose all your graphing just the one DS that may have changed.
Even if you have one that changed at least you can still look at the old
rrd and have history to look at. So in your case you have a new DS and like
magic a new rrd is created. </span><span style='font-size:12.0pt;

I will try very soon and keep you in touch with this. In a more general way do
you (the list) think that, in the future, it will be possible to easily add or
remove DS definition inside rrds ? Actually, i’s a pain to add new
DS definition inside rrd without do a rm xxx.rrd and let Xymon to recreate it.
If you have a clue…<o:p></o:p></span></p>

<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m sorry for asking you this question again but I
really can’t figure how to graph a sum of values coming from other
graphes. Basically I want to make a graph of the total bandwidth consumed by a
pool of servers. For this I would like to use the values coming from the ifstat
graph of each server. What will be the best solution ?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As I said I asked this question before and got answer from
two people but I was not able to have the proposed solution working. So if you
have other ideas you’re very welcome !<o:p></o:p></p>
