[Xymon] 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

Regards, Jo

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] TITLE HDD Temperature YAXIS Degrees DEF:hda=temp.rrd:hda:AVERAGE DEF:hdb=temp.rrd:hdb:AVERAGE DEF:hdc=temp.rrd:hdc:AVERAGE DEF:hdd=temp.rrd:hdd:AVERAGE DEF:hde=temp.rrd:hde:AVERAGE DEF:sda=temp.rrd:sda:AVERAGE DEF:sdb=temp.rrd:sdb:AVERAGE DEF:sdc=temp.rrd:sdc:AVERAGE DEF:sdd=temp.rrd:sdd:AVERAGE DEF:sde=temp.rrd:sde:AVERAGE LINE2:hda#FF0000:hda LINE2:hdb#0000FF:hdb LINE2:hdc#00FF00:hdc LINE2:hdd#FFFF00:hdd LINE2:hde#FF00FF:hde COMMENT:\n GPRINT:hda:LAST:hda \: %5.1lf%s (cur) GPRINT:hda:MAX: \: %5.1lf%s (max) GPRINT:hda:MIN: \: %5.1lf%s (min) GPRINT:hda:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdb:LAST:hdb \: %5.1lf%s (cur) GPRINT:hdb:MAX: \: %5.1lf%s (max) GPRINT:hdb:MIN: \: %5.1lf%s (min) GPRINT:hdb:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdc:LAST:hdc \: %5.1lf%s (cur) GPRINT:hdc:MAX: \: %5.1lf%s (max) GPRINT:hdc:MIN: \: %5.1lf%s (min) GPRINT:hdc:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hdd:LAST:hdd \: %5.1lf%s (cur) GPRINT:hdd:MAX: \: %5.1lf%s (max) GPRINT:hdd:MIN: \: %5.1lf%s (min) GPRINT:hdd:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:hde:LAST:hde \: %5.1lf%s (cur) GPRINT:hde:MAX: \: %5.1lf%s (max) 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
