<div>Thanks for that, what was throwing me off is I have not seen it documented anywhere on which area this should be put; I was trying the File RE:. DS: and Element and Formula dialogs and all of those produced some strange results.

<div dir="ltr" align="left"><span><font face="Courier" size="2">The other guy who just replied to this is right--you need to familiarize yourself more with how rrdtool works. drraw is a great tool for helping you design graphs, but you do need some rudimentary knowledge of rrdtool to really use for more than the most basic tasks.

<div>Thanks again, I am reading up on the rrdtool site and trying to understand all this RPN stuff...I am sure there must be a logical reason for what looks to me like a very odd way to handle logic. :)</div>

<div><span class="e" id="q_10e0edeccad56a76_1">
<div></div>
<div>Hi all,</div>
<div> </div>
<div>I am using Drraw 2.1.3 to create graphs from data that is collected for Orca use on Solaris systems. Orca is good at it's own graphs but sometimes its nice to get on the fly output as well. Usually I can get simple graphs but I am at the point now where I need to do some math on the RRDs.
</div>
<div> </div>
<div>I have not been succesful in combining output from RRD files to give me a SUM, i.e. one RRD is cpu_usr, the other is cpu_system. To get the total utilization I need to add these two together but I can't figure out how to do it. Everything I have tried in the CDEF sections has failed, probably because I am at a loss as to what needs to go where.
</div>
<div> </div>
<div>Can anyone help me?</div>
<div> </div>
<div>Thanks.<br clear="all"></div></span></div></blockquote></div></blockquote></div><br><br clear="all"><br>-- <br> )<br> (<br> )<br>[_])
