Extract Temperature Data from CoreTemp

[tko1982]

I'm interested in logging CPU temperatures into an Influxdb database using the Telegraf service on Windows 10. What is the recommended way to get the current temperature readings from Coretemp? I know that Rainmeter, for instance, is able to access the current temperatures from Coretemp directly, but I'm not sure how it's accomplishing that.

Any help is appreciated!!

You can enable logging, and Core Temp will create csv log files with temperature, frequency and other info.

Is there no way to pull the data directly from Coretemp at the current time?

[The Coolest]

You can, through the shared memory interface, or by using the SDK.

So I ended up using the Delphi library posted on the developers page... it works great and I now have a program that can return the data I need for Telegraf. However, when the Telegraf service runs the program, it only returns "Error: Core Temp's shared memory could not be read."

The Core Temp application is running, and the delphi program returns data when I run it manually. Do you have any idea why the shared memory can't be read?

[The Coolest]

Is the service running under a different username? You may need to enable the global shared memory option in Core Temp's Advanced settings.

[tko1982]

That did it!!

The service is running as local system. So is the shared memory not available to users other than the one running the CoreTemp application, unless you check the "Enable Global Shared Memory" checkbox?

Thanks for your help!!

[The Coolest]

Yes, by default the shared memory is only available to the user which started Core Temp.

In case anybody is interested, I've made my program available for download.

This program outputs data in a format that can be easily read by Telegraf, an agent that submits data to a logging database. Once the data is logged, it can be visualized using a program like Grafana.

Hi @tko1982 ... sorry for a bit of a necro here, but I'm looking at your source code, and it references another file:
GetCoreTempInfoDelphi in 'libraries\GetCoreTempInfoDelphi.pas';
I pulled your project from github, using --recursive, but either way this file does not appear to be included.
Is that the library that you are referring to (at github) as being at 74.cz ?? I looked over that site, but don't see anything related to CoreTemp...

Otherwise, where can I find this file??

If anybody else is looking for the GetCoreTempInfoDelphi.pas, it is here: http://74.cz/download/GetCoreTempInfoDelphi.zip

Sorry about that!
