It tracks true time-to-ready (via SSH reachability, not pod/Running), CSI provisioner throughput under multi-disk VM loads, and live migration stun time over SDN overlays. Six built-in scenarios cover DataSource provisioning, single/multi-node boot storms, live migration, chaos operations, and failure recovery. Results are output as JSON/CSV and rendered into an interactive HTML dashboard. The tool is designed to integrate into staging CI pipelines to catch performance regressions before production, and is positioned as complementary to kube-burner and fio/iperf wrappers by measuring data-path and component interaction rather than raw micro-benchmarks or control-plane churn. ## Full article daily.dev links to this article rather than hosting it.
