Mix Kubernetes with Linux Kernel Tracing to Boost the Observability of Your Cluster

summary
An open source container-tracer project uses the Linux kernel tracing stack (tracepoints, dynamic tracing and perf-style events) to map Kubernetes pods to their underlying namespaces and processes and record syscalls, scheduling and network events. A demo shows it running against hundreds of containers in a cluster, capturing fine-grained kernel events without instrumenting application code, exporting structured traces to existing observability pipelines, and proving the approach works on production-like workloads.
