It seems that any frequency above 10 minutes doesn't work. From what I
understand, this has to do with the step and heartbeat of the rrd. It
looks like by default the step is 300 seconds and the heartbeat is 600
seconds (10 minutes). So, as long as it doesn't go above 10 minutes it
will accept data, anything past 10 minutes will be tossed which would
result in me not getting graphs.
So, in reading the man pages, I figured out that I can override the 600
second default by appending it to my ENV tags in xymonserver.cfg
NCV_MyAlert="MyAlert:GAUGE:900"
At first glance, this worked perfectly. I deleted the rrd file,
restarted xymon, did a rrd dump and the XML was now showing a heartbeat
of 900 (15 minutes). So, I set my script to run every 15 minutes
expecting a giant rainbow to arc over my screen, but, it still doesn't work.
My XML looks like this:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;
<!-- Round Robin Database Dump --><rrd> <version> 0003 </version>

custom graphs, but just change the time interval.

update your rrd definitions. The rrd databases are fixed length
files, so you are leaving lots of blank entries between data points.

I had two custom RRD graphs setup and running fine on client
systems. The script that collects the data was running every
minute. After I finished testing, I changed the frequency of
the scripts on the clients to 1 hour in the clientlaunch.cfg
file. When I did, the RRD graph stopped displaying data. It
ran like this for a couple days. I changed clientlaunch.cfg
back to 1 minute... and the graphs immediately started
graphing again. Is there a minimum time frame that is
needed, or something else that must be done? What am I missing?
