<div><font color="#1F497D">Hi all –</font></div>
<div><font color="#1F497D"> </font></div>
<div><font color="#1F497D">I wanted to change the default rrd graphs and thought this may be relatively easy but then again..</font></div>
<div><font color="#1F497D">Xymon 4.3.10</font></div>
<div><font color="#1F497D">Ubuntu 12.10</font></div>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">Currently, all of the graphs are based on 576 data points which works great for graphs that are:</font></div>
<div><font color="#1F497D">48 hours @ 5 minute average = 576</font></div>
<div><font color="#1F497D">12 days @ 30 minute average = 576</font></div>
<div><font color="#1F497D">48 days @ 2 hours average = 576</font></div>
<div><font color="#1F497D">576 days @ 1 day average = 576</font></div>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">I want to increase some of the granularity and also reduce the final graph to 1 year. So, I decided on these settings:</font></div>
<div><font color="#1F497D">(based on 864 data points)</font></div>
<div><font color="#1F497D">72 hours @ 5 minute average = 864</font></div>
<div><font color="#1F497D">9 days @ 15 minute average = 864</font></div>
<div><font color="#1F497D">27 days @ 45 minute average = 864</font></div>
<div><font color="#1F497D">360 days @ 600 minute average = 864 (I was searching for a nice number that I could use for 1 year and this was as close as I could get)</font></div>
<div><font color="#1F497D"> </font></div>
<div><font color="#1F497D">I changed rrdefinitions.cfg to match the above (I hope my numbers are right):</font></div>
<div><font color="#1F497D">RRA:AVERAGE:0.5:1:864</font></div>
<div><font color="#1F497D">RRA:AVERAGE:0.5:3:864</font></div>
<div><font color="#1F497D">RRA:AVERAGE:0.5:9:864</font></div>
<div><font color="#1F497D">RRA:AVERAGE:0.5:120:864</font></div>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">I also changed “RRDWIDTH” in xymonserver.cfg from 576 to 864.</font></div>
<div><font color="#1F497D"> </font></div>
<div><font color="#1F497D">I assumed that all of my old graphs would remain as they were and that new graphs would take on the new characteristics above.</font></div>
<div><font color="#1F497D">2 Things occurred:</font></div>
<ul style="margin:0; padding-left:36pt">
<font color="#1F497D">
<li>All the graphs grew to 864 data points in width (ok, that is fine)</li><li>All the graphs still retained the original titles “Last 48 Hours”, “Last 12 Days”, etc.</font>
</li></ul>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">I found those graph titles in showgraph.c:</font></div>
<div><font color="#1F497D">showgraph.c: glegend = "Last 12 Days";</font></div>
<div><font color="#1F497D">showgraph.c: glegend = "Last 48 Days";</font></div>
<div><font color="#1F497D">showgraph.c: glegend = "Last 576 Days";</font></div>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">That leads to these questions:</font></div>
<ul style="margin:0; padding-left:36pt">
<font color="#1F497D">
<li>I can recompile showgraph.c – should I? Is there an easier way?</li><li>If new graphs take on the new characteristics, will I be able to change the old rrd files? I understand that I can’t create data that is not already there but is there a way to transition over time?</font>
</li></ul>
<div><font face="Calibri" size="2" color="#1F497D"><span style="font-size:11pt"> </span></font></div>
<div><font color="#1F497D">Is this a crazy idea?</font></div>
<div style="margin-top:5pt; margin-bottom:5pt"><font color="#1F497D">Thanks, </font>
