Infiniband Exporter
A Prometheus exporter that collects performance counters from InfiniBand switches and HCAs for monitoring high-performance computing fabrics.
Overview
The InfiniBand exporter is a specialized Prometheus exporter designed to gather metrics from InfiniBand fabrics, which are critical for high-performance computing and data center networking. It enables monitoring of switch and host channel adapter (HCA) port counters, providing visibility into fabric health and performance.
Key Features
- Switch Port Monitoring — Collects counters from all switch ports on the fabric connected to the host.
- HCA Port Monitoring — Optionally gathers counters from host channel adapter ports.
- Unmanaged Switch Support — Beta feature to collect data like power supply and fan health from unmanaged switches via ibswinfo.
- Large Fabric Optimization — Supports run-once mode with file output for large fabrics where scrape times are prohibitive.
- Flexible Deployment — Can run with sudo, without sudo via udev rules, in Docker, or as a systemd service.
Philosophy
The exporter is built to be reliable and efficient for production InfiniBand fabrics, with considerations for performance on large-scale deployments and flexibility in deployment methods.
