Beyond pass or fail: The new era of chaos engineering
Binary pass/fail uptime testing no longer suffices for cloud-native deployments because a cluster can remain operational while dropping packets, breaching SLOs, or suffering performance degradation. Krkn addresses this with a trifecta of telemetry: a weighted Resiliency Score, continuous HTTP Health Checks, and KubeVirt Checks. The Resiliency Score is a 0–100% macro-health metric that evaluates live Prometheus data against pre-defined SLOs using custom weights, allowing engineers to prioritize business-critical components like authentication or payment gateways. HTTP Health Checks probe application endpoints at configurable intervals, capturing exact downtime start and end times alongside HTTP status codes, enabling teams to track self-healing duration. KubeVirt Checks monitor virtual machine instances via real-time SSH connectivity and record node, IP address changes, and exact down-time, with a final post-chaos check that flags VMs remaining unreachable after the experiment concludes.
