Debugging Your Cluster When It's on Fire#

• Why: The new OpenTelemetry eBPF Instrumentation project promises zero-config, on-demand distributed traces and connectivity graphs added to a live cluster without touching app config — a genuinely different operational capability worth seeing even if it's outside core networking design.
• What: A demonstration of adding deep, language-agnostic telemetry to a misbehaving production cluster with no application or cluster config changes, via OTel eBPF instrumentation. (from abstract only)
• How: Uses eBPF-based auto-instrumentation to produce on-demand distributed traces and service connectivity graphs in-situ. (from abstract only)
• Where applicable: Any Kubernetes cluster needing emergency observability; general, dependent on the OTel eBPF project's maturity.
