This will change your step to 5 seconds. Note, that you will
probably want to change your heartbeat to a value greater than
your step. By setting your heartbeat = step, you are running a
probable scenario of missing data. Your heartbeat should be
greater than your step, I'd recommend double, if not triple.<tt><br>
<br>
</tt>Both step and heartbeat are set when the rrd file is created,
you cannot change them on the fly. If you do not wish to lose
existing data, you will need to run "rrdtool tune -h threads:10"
to change your heartbeat. Then, you will need to dump your rrd
to a file, edit the xml step with a text editor, then restore your
rrd from the edited xml,<br>
<br>
rrdtool dump httpd_threads.rrd > threads.xml<br>
edit the threads.xml setting step to 5<br>
rrdtool restore threads.xml httpd_threads.rrd<tt><br>
<br>
</tt>If you plan on doing this on several hosts, or plan on doing
it frequently, I suggest you write a script and utilize the xymon
grep utility.... it will make your life considerably easier.<tt><br>

Hi
<div><br>
</div>
<div>I need to do a temporarily graph with a very low frequency :
5 seconds instead of the regular 300 seconds.</div>
<div><br>
</div>
<div>1/ On client side, the external script is simple:</div>
<div><br>
</div>
<div>
<div>[ buda ext]# cat httpd_threads.sh </div>
<div>#!/bin/bash</div>
<div>THREADS_HTTP=`ps -ef | grep -c [h]ttpd`</div>
<div>LINE="data $MACHINE.trends</div>
<div>[httpd_threads.rrd]</div>
<div>DS:threads:GAUGE:5:U:U $THREADS_HTTP"</div>
<div>$BB $BBDISP "$LINE"</div>
<div><br>
</div>
</div>
<div>So, as you can see, the step is 5 in the DS.</div>
<div><br>
</div>
<div>clientlaunch.cfg has "INTERVAL 5s".</div>
<div><br>
</div>
<div>2/ On Xymon server side : </div>
<div><br>
</div>
<div>rrddefinitions.cfg :</div>
<div>
<div><br>
</div>
<div>
<div># step = 5 seconds</div>
<div>[httpd_threads/5]</div>
<div> # 576 * 60 * 5 sec = 48 h soit 2 jours sans perte</div>
<div> RRA:AVERAGE:0.5:60:576</div>
<div> RRA:AVERAGE:0.5:360:576</div>
<div> RRA:AVERAGE:0.5:1440:576</div>
<div> RRA:AVERAGE:0.5:17280:576</div>
</div>
<div><br>
</div>
<div><br>
</div>
<div>
<div># This one is the default setup. You can change it, if
you like.</div>
<div>[]</div>
<div> # 576 datapoints w/ 5 minute interval = 48 hours
@ 5 min avg.</div>
<div> RRA:AVERAGE:0.5:1:576</div>
<div> # 576 datapoints w/ 6*5 minute averaged = 12 days

<div>3/ RRD created:</div>
<div><br>
</div>
<div>here the issue, the step is still 300. The
minimal_heartbeat is 5.</div>
<div><br>

<div>How can i change the step to 5 instead of 300 ?</div>
<div><br>

<div>Thanks for your help.</div>
