The prevailing view now posits that the inherent reasoning capabilities of large language models (LLMs) are no longer the primary constraint. Instead, the more formidable challenge lies within the intricate data pipelines that meticulously curate and deliver information to these sophisticated AI systems. This paradigm shift carries significant practical implications for teams integrating LLMs into their incident response strategies, suggesting that substantial investment in preparing high-quality, contextually relevant data may yield superior results compared to simply opting for larger, more powerful AI models.<\/p>\n<p>The evolution of AI in RCA can broadly be categorized into two distinct architectural approaches: agent-based designs and deterministic designs. In agent-based systems, LLMs are empowered with a suite of tools, enabling them to independently investigate issues. They actively select and fetch telemetry data as their reasoning process unfolds, mimicking a human analyst&#8217;s investigative workflow. Conversely, deterministic designs operate on a pre-computation model. Here, signals are correlated and analyzed upfront, and the LLM is presented with a single, precisely prepared context. This latter approach is gaining traction, as evidenced by Coroot&#8217;s recent work and mirrored in platforms like Dynatrace&#8217;s Davis AI. Davis AI, for instance, relies on deterministic, topology-based causal analysis, navigating a real-time dependency map to pinpoint root causes rather than engaging in an open-ended, agent-driven exploration.<\/p>\n<p>The inherent difficulty in evaluating the success of AI-driven RCA stems from the intertwined nature of these two components: the model&#8217;s reasoning and the data it receives. When an AI fails to identify a root cause, it becomes challenging to ascertain whether the deficiency lies in the LLM&#8217;s analytical prowess or in the inadequacy of the provided evidence. This ambiguity has spurred efforts to disentangle these variables, with recent research from observability vendor Coroot taking a leading role.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/lockitsoft.com\/?p=7048\/#Disentangling_Reasoning_from_Data_Preparation\" >Disentangling Reasoning from Data Preparation<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/lockitsoft.com\/?p=7048\/#Model_Performance_Under_Controlled_Conditions\" >Model Performance Under Controlled Conditions<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/lockitsoft.com\/?p=7048\/#The_Trade-offs_Flexibility_vs_Operability\" >The Trade-offs: Flexibility vs. Operability<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/lockitsoft.com\/?p=7048\/#The_Economics_of_Context_Engineering\" >The Economics of Context Engineering<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/lockitsoft.com\/?p=7048\/#The_Future_of_AI_in_Incident_Response\" >The Future of AI in Incident Response<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"Disentangling_Reasoning_from_Data_Preparation\"><\/span>Disentangling Reasoning from Data Preparation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In a significant exploration of this challenge, Coroot engineer Nikolay Sivko meticulously dissected the process of LLM-assisted RCA into two discrete functions: the model&#8217;s ability to reason over presented data, and the &quot;harness&quot; \u2013 the system responsible for selecting, shaping, and delivering that data to the model. Sivko&#8217;s research, detailed in Coroot&#8217;s blog post, posits that the question &quot;can AI do RCA?&quot; is too broad. Instead, he argues for an independent evaluation of these two crucial components.<\/p>\n<p>Coroot&#8217;s innovative pipeline exemplifies the deterministic approach. It correlates incoming signals into actionable findings and then presents this consolidated information to the LLM within a singular, focused context. Crucially, this design eschews an agent loop, thereby ensuring that any incorrect diagnosis can be definitively attributed to the LLM&#8217;s reasoning rather than to the absence or misrepresentation of critical evidence.<\/p>\n<p>To rigorously test this hypothesis, Sivko devised a controlled experiment. He simulated a network latency issue using Chaos Mesh&#8217;s NetworkChaos functionality. This experiment deliberately introduced delays between a catalogue service and its associated PostgreSQL database. The intended consequence was to slow down database queries, ultimately leading to 502 errors on the front-end. To introduce an element of complexity and test the robustness of the system, the prepared context deliberately included misleading signals. These misleading signals, such as query timings artificially inflated by network round-trip time, were designed to potentially divert the AI&#8217;s attention from the true root cause.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Model_Performance_Under_Controlled_Conditions\"><\/span>Model Performance Under Controlled Conditions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Sivko then subjected this carefully constructed scenario to a battery of eleven different LLMs. Each model received the same prompt, approximately 9,800 tokens in length, and was tasked with identifying the root cause of the issue, outlining the cause-and-effect chain leading to the problem, and proposing an immediate remediation.<\/p>\n<p>The results offered a fascinating glimpse into the current capabilities of various LLMs. Among the top-tier, closed-frontier models, Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro all successfully navigated the complex scenario. They accurately identified the Chaos Mesh experiment as the root cause and correctly prescribed the necessary actions: deleting both the experiment and its associated schedule.<\/p>\n<p>Larger, open-weight models generally performed commendably, keeping pace with their proprietary counterparts. However, a clear stratification emerged when evaluating self-hostable models. Gemma 4 31B stood out as the sole model within this category capable of pinpointing the correct root cause. In contrast, larger open-weight models like Qwen3.6 35B and Qwen3 C (Coder Next) faltered, failing to identify the underlying issue. This disparity highlights the ongoing advancements in open-source LLM development, but also underscores the continued advantage held by some closed-source models in complex reasoning tasks when presented with carefully engineered data.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_Trade-offs_Flexibility_vs_Operability\"><\/span>The Trade-offs: Flexibility vs. Operability<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>While Coroot&#8217;s findings do not definitively settle the debate between agent-based and deterministic approaches, they strongly support the latter&#8217;s growing appeal. Agent-based systems, by their nature, retain a distinct advantage in their ability to fetch data dynamically. This flexibility is invaluable for diagnosing novel incidents that fall outside the scope of predefined correlation sets, as the model can actively seek out unforeseen signals.<\/p>\n<p>However, this adaptability comes at a significant cost in terms of operability and debuggability. Real-world accounts from organizations like ZenML and Incident.io, which have implemented multi-agent LLM investigations, consistently describe them as notoriously difficult to debug in production environments. A failed run in such systems rarely yields a clean, traceable stack trace. Instead, it results in a chaotic interplay of unpredictable prompt interactions and emergent, often inscrutable, coordination between multiple agents.<\/p>\n<p>This inherent fragility is a major driver pushing many practitioners towards more deterministic workflows. Engineers discussing this trade-off on platforms like Reddit report a growing trend of abandoning fully agentic designs in favor of predominantly deterministic workflows that incorporate a narrowly focused LLM step. The primary motivations cited are enhanced reliability and reduced operational costs, particularly concerning token consumption. Deterministic pipelines, while sacrificing some of the agents&#8217; exploratory flexibility, gain significantly in repeatability and ease of evaluation. This robustness is precisely why the industry is increasingly directing its focus towards optimizing the data pipeline \u2013 the &quot;harness&quot; \u2013 rather than solely concentrating on the LLM itself as the most challenging aspect of AI RCA.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_Economics_of_Context_Engineering\"><\/span>The Economics of Context Engineering<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The cost-effectiveness of this shift is also a significant factor. Sivko observed that even with frontier models, a single, concise LLM call typically incurs costs in the range of a few cents. This is largely because the computationally intensive signal correlation and data preparation work is performed <em>before<\/em> the LLM is invoked. This observation reinforces his judgment that the reasoning component of AI RCA is &quot;basically solved.&quot; The true frontier of engineering effort, he contends, now lies in &quot;preparing the right, compact context for the model before you call it.&quot;<\/p>\n<p>This perspective aligns with a broader industry-wide emphasis on &quot;context engineering.&quot; Leading AI research organizations and platform providers are converging on a similar understanding. Anthropic, in its guidance on effective context engineering for AI agents, and LangChain, a prominent framework for developing LLM-powered applications, both advocate for this approach. Similarly, observability vendor Mezmo highlights context engineering as crucial for delivering the right data to LLMs in an observability context. The common thread running through this guidance is the recognition that curating the most concise set of high-signal data is rapidly becoming a core discipline for ensuring the reliability and efficacy of LLM-based reasoning and observability solutions.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_Future_of_AI_in_Incident_Response\"><\/span>The Future of AI in Incident Response<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The implications of this evolving understanding are profound for the future of incident response. As organizations continue to grapple with increasingly complex distributed systems and the relentless velocity of software development, the ability to rapidly and accurately diagnose and resolve issues is paramount. LLMs offer a powerful promise in this domain, but their effective deployment hinges on a sophisticated understanding of data management and preparation.<\/p>\n<p>The shift from prioritizing raw model power to optimizing data pipelines signifies a maturation of the AI in IT operations (AIOps) field. It suggests that the next wave of innovation will not necessarily be about building bigger, more intelligent LLMs, but rather about developing more intelligent and efficient systems for feeding them the right information. This focus on the &quot;harness&quot; will likely lead to advancements in:<\/p>\n<ul>\n<li><strong>Automated Signal Correlation and Enrichment:<\/strong> Developing more sophisticated algorithms that can automatically identify relevant signals, filter out noise, and enrich data with contextual information (e.g., deployment history, recent configuration changes, user impact).<\/li>\n<li><strong>Intelligent Data Sampling and Filtering:<\/strong> Techniques that can dynamically select the most pertinent data points for an LLM based on the nature of the incident, reducing both token costs and cognitive load on the model.<\/li>\n<li><strong>Explainable AI for Data Pipelines:<\/strong> Creating mechanisms to understand <em>why<\/em> certain data was presented to the LLM and <em>why<\/em> other data was excluded, improving the debuggability and trustworthiness of the entire RCA process.<\/li>\n<li><strong>Domain-Specific Context Engineering:<\/strong> Tailoring data preparation pipelines to specific application architectures, technology stacks, and business domains to maximize the relevance and accuracy of the LLM&#8217;s analysis.<\/li>\n<\/ul>\n<p>By focusing on the precision and relevance of the data provided, organizations can unlock the full potential of LLMs in root cause analysis, transforming incident response from a reactive, often chaotic process into a more proactive, data-driven, and ultimately, more efficient operation. The success of AI in this critical area will be less about the model&#8217;s innate intelligence and more about the intelligence of the systems that empower it.<\/p>\n<!-- RatingBintangAjaib -->","protected":false},"excerpt":{"rendered":"<p>A burgeoning consensus among observability engineers is reshaping the landscape of AI-assisted root cause analysis (RCA).
