Speedfan query

[michalikt]

I am interested in getting a copy of the commandline program of yours that MRTG calls to query the speedfan shared memory.

I will package it up for you tonight if I can, if you don't have anything by tomorrow, PM me

Hello Phil,

Can you share the Windows command-line version of the utility that get the Speedfan shared memory data. I am interested in the 32-bit Vista & 64-bit Win7 version.

Thanks

[phil]

This should work for all versions of windows (x86 and x64) to read the data from speedfan
It outputs it in a mrtg suitable format.

Thanks,
Phil

Hi there

ReadSpeedFan.exe outputs decimal values on my system, and mrtg is complaining with evaluated to 'NaN' instead of a number in the log file.

Example output:

Code: Select all

38,0
84,5

Temperature sensor 1
Temperature sensor 2

Is SpeedFan to blame for using a comma, or is it just your program that's being very polite and sticking with the system's regional settings?

Got any tips for how to fix this?

[phil]

I guess my program is sticking with the regional settings - thats not surprising because it just does a string format/printf which would do that.

I hadn't even considered that being a problem but I guess it wont be difficult to fix (assuming I can find the original code )

I'll try and take a look when I get home from work.
Thanks,
Phil

Have a go with this one...
I'm now forcing the format specifically rather than forcing a regional setting that can be modified in Windows!

o.O

Wow, fast response.
And now it works
Superthanks, mate.


I have a request for you, though...
With the newer versions of SpeedFan you have possibility to pull data from SpeedFan with xAP.
Maaaaybe, a small program to use xAP instead of snatching data from shared memory?
(In this way you can poll a SpeedFan installed on a remote computer.)

[phil]

I'm not familiar with xAP I will have to read up on that
Maybe thats for someone else as I'm rather busy with my other projects right now, but I will try and have a look at some point!

Thanks, and glad it works now
Phil

Hi again!

Just a small note - nothing important...
Your exe outputs 5 lines in total, but MRTG requires 4 lines.
The two first lines are of course ok, but the two last lines should be
- uptime in human readable form
- computer name

I didnt notice this until now as I only use the two first lines in my MRTG config.
(I'm generating the two last lines myself using windows commands)

I've been using readspeedfan.exe for a couple of weeks now, and it work's beautifully

[phil]

interesting, I don't understand why that is not a problem on my graphing then. I will see what I can do about it

[Irios]

Well, the three last lines in the current readspeedfan.exe output is like this

3) *blank line*
4) sensor name 1
5) sensor name 2

MRTG reads only line 3 and 4. So system uptime = blank, and computer name = sensor name 1. Thats why it doesnt really pose a problem. Like I said, it's not something to worry about. But if you're gonna make any changes to your code in the future, you might look into fixing it.

I'm writing a HOWTO/FAQ on cofiguring MRTG for Windows, and I'd like to link to your website if it's OK, as your readspeedfan.exe is quite interesting for people wanting to graphs their sensors

EDIT: typo

[phil]

No problem with the links - my config examples are ancient now, and I'm using RRDTool more than just mrtg because it works with negative numbers eg. (outside temperature) where as mrtg alone does not.
