Kernel Observability for Data Movement

This article explains that traditional user-space observability often misses critical runtime data movement because system calls and kernel-mediated events are the authoritative source of file, process, and network activity. It advocates using kernel-level instrumentation (e.g., eBPF) to build real-time behavioral graphs that provide ground-truth visibility across hosts and containers, and describes Hilt's platform approach for continuous data-movement governance without modifying applications.
