This article presents a lightweight, non‑intrusive eBPF‑based method for instantly identifying Redis big‑key operations, explains the underlying kernel and user‑space implementation, provides complete code samples, and evaluates performance before and after optimization.
This article explains how to monitor Go goroutine state transitions without modifying source code by attaching eBPF uprobes to the runtime.casgstatus function, defining a custom data struct, using a ring buffer to deliver events, and processing them in a Go user‑space program.
Didi’s observability platform leverages non‑intrusive eBPF probes to automatically capture and validate service‑to‑service call tuples, supplement missing SDK data, achieve roughly 80 % core‑path coverage, and address verification challenges while planning future user‑space VM hooks and deeper MTL integration.
