Show HN: AI SRE Arena, an Open Benchmark for AI SRE Agents on Kubernetes

AI SRE Arena is an open-source benchmark for evaluating AI Site Reliability Engineering agents on Kubernetes, providing a vendor-neutral framework to deploy test clusters, inject faults, and score how well different products investigate incidents. The benchmark compared Edge Delta's native AI investigations, Grafana's native AI investigations, and Claude across 21 Kubernetes scenarios, with results showing Edge Delta detected 85.7% of incidents while Claude achieved 90.5% accuracy in root cause analysis on Grafana's platform. The tool enables standardized evaluation of AI-driven incident investigation capabilities through configurable testing and scoring mechanisms.
