Towards Real-Time NVMe Monitoring (nvme-top)
summary
Proposes nvme-top: a real-time NVMe-oF multipath monitor built as an nvme-cli-integrated proof of concept that polls sysfs once per second to refresh a two-level dashboard (subsystem summary and per-path drilldown) and renders with a lightweight termios UI. Displays per-path IOPS, latency, bandwidth, inflights and ANA state plus proposed retry/failover/error counters (not yet in kernel). Shows that polling is sufficient for a demo, outlines kernel changes to expose counters via sysfs and Grafana export.
