Fan speed and system temperature via MRTG

Hi all

I'm trying to use MRTG to graph the fan speed and system temperature. This is an excerpt of my mrtg.conf:

Target[fan]: .1.3.6.1.4.1.4526.18.4.1.2&.1.3.6.1.4.1.4526.18.4.1.2:public@127.0.0.1
Options[fan]: gauge, nopercent, noo
MaxBytes[fan]: 5000
Title[fan]: Fan
PageTop[fan]: <H1>Fan</H1>
YLegend[fan]: RPMS
ShortLegend[fan]: RPMS
LegendI[fan]: Rear fan
WithPeak[fan]: ymwd

Target[temperature]: .1.3.6.1.4.1.4526.18.5.1.2&.1.3.6.1.4.1.4526.18.5.1.2:public@127.0.0.1
Options[temperature]: gauge, nopercent, noo
MaxBytes[temperature]: 100
Title[temperature]: Temperature
PageTop[temperature]: <H1>Temperature</H1>
YLegend[temperature]: Celcius
ShortLegend[temperature]: C
LegendI[temperature]: System
WithPeak[temperature]: ymwd


The OID numbers are coming from http://www.oidview.com/mibs/4526/READYNAS-MIB.html. I'm not having any luck though, because MRTG is telling me this:

SNMP Error:
Received SNMP response with error code
  error status: noSuchName
  index 2 (OID: 1.3.6.1.4.1.4526.18.4.1.2)

 at /usr/bin/mrtg line 1840


... and a similar message for the temperature.

What am I doing wrong?

Best regards
Bram

    I'd be very interested in your procedure to get this going as I have had no luck ... thanks

    Yes, I have.

    I've created a little step-by-step: http://www.evernote.com/shard/s36/sh/250ea1a4-a0f9-4976-8d60-e72afc68c59a/28399ef87d3d250b2a8c17631e03887e

    Send me a PM with your e-mail address if you want the relevant Perl modules and the config I created in your mailbox.

    The configs... With these I can monitor about every aspect of the system, and even the influence of the sun on my garage. A similar configuration is possible on the ReadyNAS Duo. Don't know about other ReadyNAS devices.
