Xymon Graphs

Hello,

I'm using multiple RRD (one per disk) and serial number as disk reference. The graph uses FNPATTERN to graph 'all files for a host'.

See my notes here http://www.tumfatig.net/20120426/monitor-synology-disk-temperature-from-snmp/
The graph definition is:
[snmp_disktemp]
        FNPATTERN ^snmp_disktemp.(.+).rrd
        TITLE Disk Temperature
        YAXIS Celcius
        -l 0
        -E
        DEF:temp at RRDIDX@=@RRDFN@:temp:AVERAGE
        LINE:temp at RRDIDX@#@COLOR@:@RRDPARAM@
        GPRINT:temp at RRDIDX@:LAST:%3.0lfC (cur)
        GPRINT:temp at RRDIDX@:MIN:%3.0lfC (min)
        GPRINT:temp at RRDIDX@:AVERAGE:%3.0lfC (avg)
        GPRINT:temp at RRDIDX@:MAX:%3.0lfC (max)\l

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

                <min>NaN</min>
                <max>NaN</max>

                <!-- PDP Status -->

                <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:

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,
