OhmGraphite

OhmGraphite

OhmGraphite takes the hard work of extracting hardware sensors from Open Hardware Monitor (technically LibreHardwareMonitor for most up to date hardware) and exports the data in a graphite compatible format. If you're missing GPU, temperature, or power metrics in Grafana or (or other graphite UI), this tool is for you!

OhmGraphite functions as a console app (cross platform) or a Windows service that periodically polls the hardware. My recommendation is that even though OhmGraphite can be run via Mono / Docker, many hardware sensors aren't available in those modes.

Don't fret if this repo hasn't been updated recently. I use this every day to create beautiful dashboards. Keep in mind, Open Hardware Monitor supported components will determine what metrics are available. Below are graphs / stats made strictly from OhmGraphite (additional Windows metrics can be exposed, see Monitoring Windows system metrics with grafana)

Getting Started (Windows)

• Create a directory that will home base for OhmGraphite (I use C:\Apps\OhmGraphite).
• Download the latest zip and extract to our directory

• Update app configuration (located at OhmGraphite.exe.config) to include the host and port of graphite and the hardware polling interval. This config can be updated in the future, but will require a restart of the app for effect.

  <?xml version="1.0" encoding="utf-8" ?>
  <configuration>
  <appSettings>
  <add key="host" value="localhost" />
  <add key="port" value="2003" />
  <add key="interval" value="5" />
  </appSettings>
  </configuration>
  

• The app can be ran interactively by simply executing OhmGraphite.exe. Executing as administrator will ensure all sensors are found.

• To install the app .\OhmGraphite.exe install. The command will install OhmGraphite as a Windows service (so you can manage it with your favorite powershell commands or services.msc)

• To start the app after installation: .\OhmGraphite.exe start or your favorite Windows service management tool

Getting Started (Docker)

Since the full gambit of metrics aren't available in a Docker container, I've refrained from putting the project on docker hub lest it misleads people to think otherwise.

docker build -t nickbabcock/ohm-graphite .
docker run -v $PWD/app.config:/opt/OhmGraphite/OhmGraphite.exe.config:ro nickbabcock/ohm-graphite

app.config is in the same format as the above configuration.
