OhmGraphite

What it does

Certificate handling

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

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.checked 11 Oct 2026

Customization

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

Hardware support

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

Installation

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

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.checked 11 Oct 2026

Limit

When using Postgres or TimescaleDB, the database schema and columns are not configurable.checked 11 Oct 2026

Metric stores

Supported destinations are Graphite, InfluxDB, Prometheus, Postgres, and TimescaleDB.checked 11 Oct 2026

Prometheus mode

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

Purpose

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

Sensor access

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

Sensor metrics

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

Support

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