How does xymon handle graphing file system utilization. However it does that thwn I would think you could do same thing as hists have many different numbers of filesystems or drive letters in the windows world.

I have done the same thing you are trying to do using devmon and SNMP-Informant which exposes WMI data through SNMP. Then you can choose to display 1 graph per disk or group a number together. devmon sends its data via the status message as below: <!--DEVMON RRD: dperf 0 0 DS:qlen:GAUGE:600:0:U DS:bps:GAUGE:600:0:U DS:rbps:GAUGE:600:0:U DS:wbps:GAUGE:600:0:U C 0:124800:0:124767 D 0:0:0:0 Total 0:124774:0:124767 HarddiskVolume1 0:0:0:0 --> The same thing can be done with a data message to trends pseudo-column (good idea to also send a status message to create a page with current data values) which I have done with various Powershell monitoring scripts - note 1 block per disk, but the RRD definitions are repeated: data myhost.trends [dperf.C.rrd] DS:qlen:GAUGE:600:0:U 0 DS:bps:GAUGE:600:0:U 124800 DS:rbps:GAUGE:600:0:U 0 DS:wbps:GAUGE:600:0:U 124767 [dperf.D.rrd] DS:qlen:GAUGE:600:0:U 0 DS:bps:GAUGE:600:0:U 0 DS:rbps:GAUGE:600:0:U 0 DS:wbps:GAUGE:600:0:U 0 ...
