# Description # Redfish Exporter
A Python-based Prometheus exporter for collecting power data (Watts, Volts, Amperes) from bare metal servers using the Redfish API. This tool supports multiple vendors (e.g., HPE, Supermicro).
I've createtd this python script to collect Power data to analyse Watts, Volts and Amperes. If there is a better solution, feel free to replace me. I've createtd this python script to collect Power data to analyse Watts, Volts and Amperes. If there is a better solution, feel free to replace me.

## Description
This tool collects power metrics from servers using the Redfish API and exposes them in a format compatible with Prometheus. It supports both modern and legacy Redfish API versions and handles authentication for different vendors.
---
## Features
- Collects power metrics: Watts, Volts, and Amperes.
- Supports multiple vendors (HPE, Supermicro, etc.).
- Cross-platform compatibility (Linux and Windows).
- Graceful error handling and retry logic.
- Configurable via YAML.
- Docker support.
