The record

Purpose: OhmGraphite is a Windows service that exports hardware sensor data to a metric store for dashboards in Grafana or another time series UI.
Sensor metrics: Example metrics include CPU and GPU power, voltages, frequencies, component load, temperatures, disk activity and space, fan speed, and network consumption.
Metric stores: Supported destinations are Graphite, InfluxDB, Prometheus, Postgres, and TimescaleDB.
Hardware support: Hardware sensor support is provided through LibreHardwareMonitor, and detected sensors depend on the computer's hardware.
Installation: The README instructs users to download a ZIP, configure the app, and install it as a Windows service; it can also run interactively.
Sensor access: PawnIO enables access to sensors such as CPU temperature, wattage, and frequency; without it, OhmGraphite works but emits limited data.
Prometheus mode: The Prometheus exporter listens for scrapes and polls hardware sensors when scraped; the README documents optional HTTPS configuration.
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.
Certificate handling: The README says server certificates are verified by default and documents importing a server certificate for connections using self-signed certificates.
Customization: Users can rename or hide individual sensors and disable sensor collection for hardware categories such as CPU, GPU, network, or storage.
Limit: When using Postgres or TimescaleDB, the database schema and columns are not configurable.
Support: The README directs users who remain stuck to open a GitHub issue and include relevant log excerpts.
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.
