[Xymon] Xymon Graphs

[Joel Carnat]

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
