eBPF for Linux Observability
eBPF lets you run small, safe programs inside the Linux kernel without changing kernel code. It gives deep visibility into syscalls, network flows, and process behavior with low overhead, making it the modern backbone of tracing and security monitoring on Linux hosts.
要点
- Use eBPF-based tools for syscall tracing, network flow analysis, and process monitoring.
- Prefer kernel-bundled and well-tested tools over custom eBPF programs in production.
- Monitor overhead and disable probes that add latency under load.
- Combine eBPF metrics with existing Prometheus or Grafana pipelines.
- Use eBPF for security signals like unexpected process execution or network connections.
- Keep kernel versions supported by your observability stack and test upgrades.
- Restrict eBPF loading to privileged users and audit its use.
- Document which probes are active so performance regressions are traceable.
よくある質問
Is eBPF safe to run in production?
Yes when using mature tools. Custom programs need testing and review like any kernel-adjacent code.
Does eBPF replace agents?
It complements them. eBPF gives kernel depth; agents still handle logs and metrics collection.
What kernel version do I need?
Modern features need relatively recent kernels. Check each tool's requirements before standardizing.
Can eBPF hurt performance?
Poorly chosen probes can. Measure overhead and keep only high-value signals.
