Profiling NFS I/O with eBPF: From Perf Events to Pyroscope Flame Graphs

This article explains how to use eBPF and perf events to trace NFS read/write system calls, capture kernel and user stack traces, resolve them to source locations via DWARF, and generate flame‑graph data that is pushed to Pyroscope for performance analysis.
