[Xymon] Xymon Graphs

[Adam Goryachev]

Hi, I've written a quick addon to collect the temperature of each HDD in 
my system, and report the data back to Xymon like this:


      Fri Aug 24 02:33:11 EST 2012 Temp GOOD (27 degrees)

sda : 27
sdb : 27


Also, hobbit is putting this data in to an RRD file called temp.rrd:

<?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>
         <step>300</step> <!-- Seconds -->
         <lastupdate>1345738019</lastupdate> <!-- 2012-08-24 02:06:59 EST -->

         <ds>
                 <name> sda </name>
                 <type> GAUGE </type>
                 <minimal_heartbeat>600</minimal_heartbeat>
                 <min>NaN</min>
                 <max>NaN</max>

                 <!-- PDP Status -->
                 <last_ds>37</last_ds>
                 <value>4.4030000000e+03</value>
                 <unknown_sec> 0 </unknown_sec>
         </ds>

         <ds>
                 <name> sdb </name>
                 <type> GAUGE </type>
                 <minimal_heartbeat>600</minimal_heartbeat>
                 <min>NaN</min>
                 <max>NaN</max>

                 <!-- PDP Status -->
                 <last_ds>39</last_ds>
                 <value>4.6410000000e+03</value>
                 <unknown_sec> 0 </unknown_sec>
         </ds>

So it looks (to me) as though all that is working.

I'm now trying to get the pretty graph to show up, here is my current definition which doesn't work:
[temp]

         GPRINT:hde:MIN: \: %5.1lf%s (min)
         GPRINT:hde:AVERAGE: \: %5.1lf%s (avg)\n

I think the problem is that not every machine will have the same number 
of disks, nor will they have the same type of disk. Can anyone suggest 
how to re-write this so that it will work?

Thanks,
Adam
