OhmGraphite

Spec sheet

Purpose

OhmGraphite is a Windows service that exports hardware sensor data to a metric store for dashboards in Grafana or another time series UI.Read 11 Oct 2026 · github.com

Intended users

The README describes using exported hardware metrics with Grafana or another time series UI, and suggests HWINFO for people who only want a hardware-sensor GUI without configuring Grafana and a metric store.Read 11 Oct 2026 · github.com

Support

The README directs users who remain stuck to open a GitHub issue and include relevant log excerpts.Read 11 Oct 2026 · github.com

Certificate handling

The README says server certificates are verified by default and documents importing a server certificate for connections using self-signed certificates.Read 11 Oct 2026 · github.com

Credentials

Configuration values can reference environment variables so InfluxDB tokens and Postgres connection strings do not need to be stored directly in the config file.Read 11 Oct 2026 · github.com

Customization

Users can rename or hide individual sensors and disable sensor collection for hardware categories such as CPU, GPU, network, or storage.Read 11 Oct 2026 · github.com

Hardware support

Hardware sensor support is provided through LibreHardwareMonitor, and detected sensors depend on the computer's hardware.Read 11 Oct 2026 · github.com

Installation

The README instructs users to download a ZIP, configure the app, and install it as a Windows service; it can also run interactively.Read 11 Oct 2026 · github.com

Limit

When using Postgres or TimescaleDB, the database schema and columns are not configurable.Read 11 Oct 2026 · github.com

Metric stores

Supported destinations are Graphite, InfluxDB, Prometheus, Postgres, and TimescaleDB.Read 11 Oct 2026 · github.com

Prometheus mode

The Prometheus exporter listens for scrapes and polls hardware sensors when scraped; the README documents optional HTTPS configuration.Read 11 Oct 2026 · github.com

Sensor access

PawnIO enables access to sensors such as CPU temperature, wattage, and frequency; without it, OhmGraphite works but emits limited data.Read 11 Oct 2026 · github.com

Sensor metrics

Example metrics include CPU and GPU power, voltages, frequencies, component load, temperatures, disk activity and space, fan speed, and network consumption.Read 11 Oct 2026 · github.com
