<BR>
Only general/practical way to do this is to have an RRD for each
disk. 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.<BR>
<BR>
devmon sends its data via the status message as below:<BR>
<PRE><SPAN><!--DEVMON RRD: dperf 0 0
<SPAN></SPAN>DS:qlen:GAUGE:600:0:U DS:bps:GAUGE:600:0:U DS:rbps:GAUGE:600:0:U DS:wbps:GAUGE:600:0:U
<SPAN></SPAN>C 0:124800:0:124767
<SPAN></SPAN>D 0:0:0:0
<SPAN></SPAN>Total 0:124774:0:124767
<SPAN></SPAN>HarddiskVolume1 0:0:0:0
<SPAN></SPAN>--></SPAN><SPAN>
<SPAN>
</SPAN></SPAN></PRE>
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:<BR>
