<div class="moz-cite-prefix">From the rrddef.cfg comments:<br>
# Each section key is the column- or data-name reported from your<br>

<br>
In your original script:<br>
<div>
<div>[ buda ext]# cat httpd_threads.sh </div>

<div>DS:threads:GAUGE:5:U:U $THREADS_HTTP"</div>
<div>$BB $BBDISP "$LINE"</div>
<div><br>
<br>
it appears that your data name is "trends". This is what
xymon is trying to match in rrddef.cvf. The key you should be
using in rrddef.cfg. <br>
<br>
[trends]<br>
-s 5
<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>
<br>
With that said, "trends" is already a column heading... I'm
not sure that using it for your rrd key won't cause other
problems in xymon. Maybe change it to "httpd_threads"?<br>
</div>
</div>
<br>
If that doesn't work, try putting the -s in the default section
"[]", and see if that works. You shouldn't leave it there as it
will set all future graphs to a 5 second step, but it works there,
then you know your problem is with your data name and key.<br>

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>

<div>I need to do a temporarily

5 in the DS.</div>
