coretemp-exporter

CI

A Prometheus exporter that emits CPU health information such as core temperatures. There are also some example dashboards to visualize your computer's sensor data.

Building

To build coretemp-exporter you need Go and Make installed. You can use Linux or Windows hosts to build.

# (optional) Delete all build artifacts.
make clean

# Build all binaries.
make all -j$(nproc)

# Binaries are created in build/$GOOS-$GOARCH/ directory.

Running

You can run coretemp-exporter on Windows or Linux. By default it'll serve its metrics at :8081.

Linux

# Install lm-sensors
sudo apt-get install lm-sensors

# Test that lm-sensors is working.
sensors

# If it's not working try.
sudo sensors-detect

# Run coretemp-exporter.
./build/linux_amd64/coretemp-exporter

Windows

  1. Install and run ALCPU CoreTemp. It is important that this application is running otherwise you will not get any data.
  2. Install MSVC Runtime 10.
  3. Run the commands below.
# Run in the console.
.\build\windows_amd64\coretemp-exporter.exe

###################
# Windows Service #
###################

# Register Service
.\build\windows_amd64\coretemp-exporter.exe -svc=install
# Start Service
.\build\windows_amd64\coretemp-exporter.exe -svc=start
# Stop Service
.\build\windows_amd64\coretemp-exporter.exe -svc=stop
# Uninstall Service
.\build\windows_amd64\coretemp-exporter.exe -svc=remove

Dashboards

You'll need Docker and docker-compose installed. Windows users should run Docker in Linux mode.

# Go to the docker-compose directory.
cd install/compose
# Launch Prometheus and Grafana. 
docker-compose up -d

Once both services are you you can view the graphs via: :3000/dashboards. To login use the following credentials:

  • Username: root
  • Password: admin

Once you've logged in you can visit the CPU page and you should see something like:
