E4：用受限 DSL 实现互联网级服务智能体根因分析
Agentic RCA for Internet-Scale Services Using Constrained Creativity
AI 导读
研究者提出智能体系统 E4，用于互联网级服务的故障排查，其核心是"受限创造力"范式：不让 LLM 智能体写任意代码，而是给它一套受限 DSL，用无循环数据流程序生成响应。在合成与真实混合负载上，E4 准确率比现有方案最高提升 62%，成本最高降低 12 倍，同时输出更可解释、可验证。

Abstract:System administrators of Internet-scale services need to resolve failure incidents to maintain reliability of such services. Ideally, we want a troubleshooting system to be: (1) expressive to known and unknown incidents with high accuracy; (2) cost efficient at scale; (3) explainable to provide actionable insights operators can act on; and (4) entail low effort from the operators. Unfortunately, most existing systems, including emerging LLM-assisted agentic workflows and structured frameworks for authoring diverse RCA algorithms fall short of achieving all four requirements. We present E4, a novel agentic system for troubleshooting for Internet-scale services. E4 embodies the paradigm of constrained creativity that combines the best of LLM-assisted automation and exploration with the explainability and efficiency of a structured approach. Instead of allowing an LLM agent to write arbitrary code or generate arbitrary responses, we provide the agent a restricted DSL to generate its response via simple loop-free data flow programs. This DSL, equipped with high level operators for troubleshooting, makes E4's output accurate, verifiable and explainable. On a mix of synthetic and real-world workloads, E4 achieves up to 62% better accuracy compared to state-of-the-art solutions, while providing more explainable responses at up to 12x reduced cost.
