从信号到PR:构建自我修复的智能体与可观测性2.0时代 AI Engineer 2026-07-24

可观测性2.0:从人类UI到智能体驱动的自修复闭环

在软件工程的发展历程中,可观测性(Observability: 系统内部状态的度量与分析)正经历着一场颠覆性的范式转移。过去,可观测性是专门为人类设计的,表现为各种可视化UI界面、可供点击的图表以及用于检索的监控面板(如 Grafana 仪表盘)。然而,随着人工智能的爆发,我们正迈入可观测性2.0(Observability 2.0: 面向AI智能体的自动化监测与调试体系)时代。在这个新阶段,可观测性不再只是冷冰冰的数据图表,而是成为了自动化编码智能体(Coding Agents)的数字感官。

当系统出现故障时,遥测数据(Telemetry: 自动收集并传输的系统运行指标与链路数据)就如同机器排出的“烟雾”。如果没有这些烟雾,智能体在面对系统错误时就只能盲目猜测,因为程序中可能存在成千上万条执行路径。而丰富的遥测数据和日志,能够精确地告诉智能体代码在运行时到底走过了哪条路径。这使得我们能够构建能够自主定位故障、甚至自我修复(Self-fixing)的闭环系统。在未来,我们的软件工程逻辑将从“人类被动响应告警”转变为“智能体主动捕获异常并准备好修复上下文”。

Well, thank thank you all. Um, let me get set up here. So, not just the the founder of Arise, but but I tend to build an incredible amount of stuff. Um, let's see if we get this going here. Oh, sorry. One more second. Um, so not just a founder here, but but also a builder and I do my best to um uh to to to build agents assistance. Um, we have an agent in product. We have an agent in product called Alex and uh and a lot of I think a lot of my experience has come from actually um trying to make the stuff work and work well. Our first version of our our own agent frankly sucked. Uh it was many years ago uh probably two years ago when the first in the space to do it. Um and a lot of what we have built uh has come out of that our own experience in building building this agent and and signal is kind of our our next generation of this which is trying to automate a bunch of things which we do every day uh and build it into products that that people can use. Um so I'm going to try to I'm going to go through this this materials here. I'll try to go fast and try to show you a lot of product too. I'm a product person. Um, so if you've built a startup before, um, you you've experienced this, your platform's down, it's it's late at night and and you and you want to go fix it. Um, and and really the the it takes a lot of energy to go do that. And we're going to talk about like the automation we've built a little bit and and what what the future looks like and and I truly believe um that the future of the the the observability space is is actually changing massively right now. Why is that? Well, observability used to be for humans. Used to be a UI you click, a graph you click, something you look at. Um and and today it's I would argue it's a lot of 2.0 which is like this combination of coding agent. Those of you who built skills skills for um Pyroscope, Google Cloud or or whatnot, that these these skills help you with your your human debugging these systems. Um and and really telemetry is like this smoke uh thrown off of your system that can allow these agents to go make fixes. It tells you what path in the code it took. Without that, you're guessing and there's a million paths it could have taken. the the data thrown off by your system allows um allows you to to go go use agents to go debug your software. Evals add another layer to this. Um but really what we're at here is is how do I build systems that autonomously fix themselves? Really that that is what we're after. Both both AI agents, I put AI into my my my system. How do I have this thing just improve itself? and and today we're kind of in the 2.0 which is a human making fixes and reviewing things. Um but there's a future we're all driving towards and throwing off traces, throwing off logs, throwing off way more than you normally would and having agents run at this for a continuous loop is where we're going. You can build at agent speed, but today you can't improve your systems really at this agent speed. So those of us feel this this kind of governor happening within our our our our products. um and and the bottleneck is actually not the fix anymore. So those of us who've used these systems and and use used um coding agents with with skills, the the the bottlenecks, a lot of the the confidence in in do I have it right? You know, a lot of this is is about is this fix the right one to push? Um and and so these are kind of the challenges here. And then how do you how do you build this loop in a way that just moves faster?


智能体调试工作流:遥测追踪、组合式技能与冷启动修复

要在实际生产中实现这种自动修复闭环,就必须重构研发调试的工作流。目前的核心瓶颈已经不再是“如何生成修复代码”,而是“如何确保修复的正确性与置信度”。在 Arize 的设计理念中,我们颠覆了传统的“人找异常”模式:当系统发生错误事件或进行周期性巡检时,智能体会首先介入,它在人类甚至还没收到告警之前,就已经把相关的链路追踪(Trace: 记录单个请求在分布式系统中完整调用轨迹的数据)和错误日志打包。

这种模式被称为冷启动修复(Cold Start Fix: 在人类干预前由智能体完成初步诊断并准备好上下文的工作流)。智能体拥有各种组合式技能(Skills: 供智能体调用的特定工具或 API 接口),例如对接云平台的 API、内存分析工具 Pyroscope 等。它们会自动在代码仓库中下载临时的上下文文件,找到故障对应的特定执行路径。此时,人类工程师的角色从一线的“响应者”(Responder)转变为高维度的“审查者”(Reviewer)。你早上醒来,面对的不是一堆杂乱的报警,而是一个已经包含详细上下文证据、甚至附带了一两行代码修复建议的 GitHub Issue,从而大幅加速了从发现问题到合并 PR 的全过程。

Um and and a little bit of the way we we've kind of come to do it and we do it in our system is we've kind of inverted this this loop which is like a human you know looks at things and an agent uh fixes it to a person now can wake up with with an idea of the issues based upon the errors occurred in their system. So so the agent is actually you know maybe it's not a a fix itself but it's putting up an issue. It's looking at the data before a human even looks at it. Um and and what you move from there is is kind of humans grabbing tickets to to having some amount of evidence um some deep evidence relative to whatever you're looking at already sitting in front of you by the time you actually even look at it. And and human review is kind of one thing but but a lot of times maybe you're driving this little investigation a bit from where it started. So that's the reality of where we are today is there's still maybe it's not human reviewing but human driving the the step two and three. Um but but this is kind of what what we view the loop as. And really what it is is there's you know there's an event that occurs that you're kind of kicking things off on or you're looking at periodically. Um and then there's some context around that which is really driven by skills. Um, I guess a question for all of you. Who's created skills in this room? Who's created a skill that that that interfaces to an observability platform? Okay, handful. Okay, cool. Awesome. Um, so the magic of of of skills that that that connect to observability platforms um is it can gather the context. The agent can decide what it needs, what it needs to look at um to to start to troubleshoot what you have there. Um, and then there's idea of triggers which are like periodic and and um and uh and event based. And so the future observability actually looks a lot more like this than it does clicking around graphana UI. So first off evidence well normally these like or are or what do you start with what do you look at? Uh traces are are pretty nice logs as well. uh but but you know most of the AI systems these days have like traces at the core of of the agent framework. So, so you kind of start with with looking at traces and this is this could be periodic you know every five minutes this could be based upon an event an error and normally there's some combinations of these which is um you know some some like uh context and log you know context and skills used to put together logs maybe there's the repo uh you want kind of a combination of all this together um to understand what to go fix the repo tells you the code path that you know the you know all tells you everything that's there, the the production logs or traces that the agent pulls down. Um, normally our skills actually pull pull little temp files down into the the repo. Um, so that you kind of have this this this idea of what actually happened, what the code is there enough and and all that together to put up a fix. Um, so it's this combination of the right data and file format in the repo along with your code in the repo. That's kind of the magic of this skills which are composable for the agent to go actually put a fix. Um, and a lot of this, some of you, a lot of you probably do this locally today. You you run this locally. You you have an agent that you you kick up, maybe you're spinning up, but it's on your laptop. And I think we all feel this this this move from from this laptop um to to maybe to to basically sandboxes.


安全沙箱与企业VPC:智能体运行环境的隔离与部署

随着调试工作流从本地个人电脑(Laptop)转移到生产或类生产环境,智能体的运行环境(Running Environment: 代码及程序执行的物理或虚拟空间)安全变得至关重要。如果我们希望智能体能够执行自动构建、故障重现、测试甚至提交代码等复杂任务,就必须为其提供一个安全隔离的容器。此时,沙箱(Sandbox: 一种隔离的安全执行环境)技术成为了核心支撑。

在很多企业级场景中,开发人员无法直接让智能体在本地机器上访问敏感资源,更不愿意将企业的核心数据库或生产系统直接连接到第三方托管的云端大模型服务中。为了解决这一痛点,Arize 在产品架构上支持将沙箱系统部署在企业用户的虚拟私有云(Virtual Private Cloud: 逻辑隔离的私有云端网络环境)内。通过与 Daytona 等沙箱管理平台集成,企业能够在私有 VPC 中运行各种 AI 智能体集群。每个智能体的执行会话(Session)都能够被全程记录,支持下发日志、下载会话转写,甚至允许工程师在本地恢复和接管云端智能体的调试过程。这不仅消除了企业对于数据外泄和代码越权的担忧,也使得智能体在安全的边界内能够拥有读写代码库和执行调试指令的完整权限。

Original English

Um and and really the sandbox is this this running environment where um based upon an event or a periodic you know a periodic event you can kick this thing off and it does the same thing you were doing locally get it working locally first locally on your laptop and then event based based upon the observability platforms like ourselves. Um you can trigger these on a schedule or or kind of you know every every error that comes up. Um, and generally, you know, you generally it's kind of put putting the loop together to do this and and um, and I want to kind of give you one example. So, this is Alex, our agent. This is a a real example. It's a very simple one. And then I'm going to show you what it looks like in product. Um, this what we use every day. Um, but this is just an example where um, we had a stream canceled event. So um so Alex is is basically um Alex is is basically our our inproduct assistant. Um to-do update is is a uh is a is a is a way of of managing kind of its its task list. Um and it was trying to you know I'll walk you through the the error in a second but basically um it's calling a bunch of these two to-do updates and kind of um errors out and and so for us it's it's you know how do I put the data together um to debug this? how do we do it automatically and and signal is just something that's running in the background for us that's putting up like issues relative to these things. Um this was uh a kind of one or two line fix that it comes up with. These are these are ideal but a lot of times the fixes are bigger. Um and and the bigger it is the more likely a human's involved in kind of like spearheading it over the line. But again it's about that that cold start. Can I start with like all this information on the issue and guide it the rest of the way is kind of where we are right now. Um, and for us, your job kind of moves from responder to reviewer. Um, and and and the view is like traces and evals don't go away in any way, shape, or form. They're just they're they're a key part of the loop. Now, you're going to trace 10 times more. You're going to log 10 times more because that helps you know what path your software took. Before, you wouldn't do that because because humans can't dig through all the logs. It's just noise. But by logging and tracing more of your like is it every inch of your software? Maybe in some places. Um by logging and tracing orders and orders of magnitude more than we do today, we can actually create these continuous loops that know what path was taking your software and and and actually have it fix itself. So this is kind of my vision for where I think things are going. um in a way and and for us I'll show you signal in a second and you'll see all these I mean I feel like there's there's this think of this as an an SR you know something that helps you debug maybe SR for for AI um but I feel like there's a lot of black boxes out there like oh there's a SR agent that does this or S agent that does this all we're really trying to do ourselves is take your local debugging experience with cloud code cursor and run it periodically so pick your sandbox pick your harness, pick your skills, we'll pre-bank a bunch of things with you. So, we're just trying to to again take the things we were doing locally and actually run them um uh you know, run them in a system. So, we believe in you know an open approach um to this and and um I I'll give you a demo of what this looks like um from a product perspective. So, so this is um this is a a financial trading agent. Um given what you saw in the previous uh presentation, I would not recommend doing a financial trading agent. Um they they they're unlikely to make you money. Uh at least not not yet. Um maybe there's some people uh doing it good. But long story short is this one's, you know, uh people asking questions about stock trading right now and it's giving giving answers. Um there's a lot of ways this this can fail. And so this this gives you this is a rise. It's a platform. So first off from let me describe the products we have. Uh this is AX which is our our SAS platform. Um we also have Phoenix which is open source if you just want to start tomorrow. Um Signal right now is is just available in in our AX SAS platform. Um which also could be deployed VPC but but this so so give you an idea of our product lines. Uh if you want to try out Signal, it's it's an AX. Um and what it looks like is something like this, which is it's just periodically running and and kind of coming up with like issues and you can hook it up to your GitHub repo. It can create an issue in your repo. You can create an evaluator from this. Maybe u maybe there's a a specific problem by which you want to catch again. You can add these to a data set. So if you want to add these and and it has evidence associated with this like traces um in this case um in this one it has skills like for Google cloud and some other logging systems. So we can frontend a bunch of places the data we're we're pretty good at building I think these skills to debug issues again uh but you can add your own skills. So these examples here you know traces running out without a guardrail. Um there's there's um uh you know safety safety issues and intent issues and a lot of this too is like you know how does this work? How do I you know it feels a little too black box to me. Well all this is open and open box um in the sense that um I can set up you know I can set up the harness that I want it to run on. This one's cloud code. I can pick my sandboxes and sandbox systems. Um, I can use cloud managed agents if I want. I can use Arise sandbox. Uh, why would I want to use Arise sandboxes versus cloud managed agents? Well, a lot of our customers um don't want to connect their production systems to Anthropic. You know, you you you want your s you want these these sandboxes to debug your database or connect to it. So we install in the VPC of a lot of you know bigname companies out there um from from Uber to um to bookings to you name it and and these people don't want to send their connections out but they'll they'll use a s you know many many companies um are very comfortable installing a V into a VPC and actually connecting it up. So you can use Arise sandboxes or you can use Daytona or any of any of these that you're comfortable with um that you built relationships with. Um and and then from a platform perspective, you know, we support um running we support, you know, tracking the different agents that you're running. So you have this swarm of agents. Maybe you've kicked off um maybe you're kicking off a signal which which is our agent. It's running periodically. Maybe you're kicking off your you know you've named another agent um in the system. And these all support, you know, viewing the session that that ran, downloading the transcript, and you can resume a clouded session locally, too. So, the idea is that this thing's constantly running. You're picking the harness, the sandbox. You're deciding the prompt if you want, hey, don't be aggressive or look for, you know, look for security issues. So, you're deciding the prompts that drive this and you're also deciding the skills that go along with this. So um in a preset here um I can add you know add different skills. I can add my own skills. I can link repos. I can I have pre-baked skills too. Um so the ideas observability platforms are really starting to get are becoming tied to the continuous loop to the the fix not just the the signal. Um and and you you want to take your local experience you have debugging the stuff locally. You want to take the evals that are running and and actually have these all work in something that puts up a fix or at least gets you a cold start and then I can take it over locally if I want to continue debugging uh from from here. Um, so this gives you um a rough idea of of kind of of of signal to PR um what we're doing. Um, I did want to offer, you know, questions if people people have any questions on what we're doing or how we see uh the industry evolving. Happy to happy to answer. Thank you.


在线评估与大模型裁判:基于Trace的规模化故障捕获

在面向AI智能体的可观测性设计中,在线评估(Online Evals: 在生产运行中实时对大模型输入输出进行的质量与安全评估)成为了除了链路追踪和日志之外的第三大支柱。通常,评估器会以流水线的形式叠加到生产环境的 Trace 数据上。当智能体运行时,它会从追踪链路上抓取中间结果,对各项数据进行实时聚合和评估。

为了保证评估的效果与效率,我们引入了大模型裁判(LLM-as-a-Judge: 利用大语言模型作为评判标准来评估其他模型输出的自动化机制)。你可以预先针对某些特定的已知故障(例如:特定的提示词注入漏洞,或者是某次在特定场景下的回答失误)设计专门的评估器。这些运行在后台的“裁判”会不断分析系统的海量实时请求。一旦捕获到特定的错误特征,评估系统就会触发 Signal 智能体进行热修复或产生告警,在保障应用安全的防护栏(Guardrails)不被逾越的同时,实现自动发现、自动构建测试用例,并最终回流迭代系统。

Yeah. Go ahead. question of like why can't we just connect cloud code to your data and have cloud code do all these things. I think there's like a version of that question that can probably be asked for these autofixes, right? Like why not have cloud code read the traces and push the PR itself. >> I'm curious how you would respond to that question. >> Yeah. Uh so so why wouldn't have cloud code kind of hook to your your data and just just do it? Um the answer is like you should um like like the vision and what we do actually at at Arise is we have uh a lot of skills. I think first off to to make that really work well you have to do a bit of well-designed skills in the data space. The skill like the the important things of designing these skills are are around really around getting data you know finding the right data first. So I want to find a group of traces relative to a session or something. Getting that data into the repo in a file format. These harnesses are magical with files. So you get the file what happened. In some cases we have 10meg files like sitting in the repo. Um so it's designing the skill to be really really well done with the um with this data and and then giving claude enough skills to be composable to find issues. So the answer is absolutely yes. like we have Pyroscope skills that will find memory issues. We have facets in Pyroscope that the skill knows how to use. I can cohort by customer to see if a customer is causing an issue. Um but but you've got to kind of design the skill surface area in a way that Claude can really really work well and and and it's not just like point Claude at the data. >> I see. Thank you. >> Any other questions? Anyone else? >> Oh yeah. Okay. One more. Thanks for the talk. Um, there was quite a few mention of eval but you know I'm looking at the traces so you know I understand the concept of traces but where where did the evals come in when you have that signal that says hey something broke in production. >> Yeah. So so the so the eval typically will the um the eval essentially are running and being layered on typically to the production traces something we call online evals. Um let me see if this one has an example here of it. Um so so eval actually are data on the trace itself and so the agent knows how to uh grab the data from traces knows how to um visualize and you know the skills to basically pull data for for the aggregate values of evals across the traces so that so the the skills that you give uh the harness allow it to get the data on the eval from from the traces. Um so eval are kind of like I view them as le at least a first generation eval evals which are elements a judge um as a as a AI layer that allows you to run periodically and and assess your system but it's like it but it's adding a little bit more you know pre-processed information on the data that that and then as signal is running it's using data from the evals that were layered on um in addition to all the raw data that it has there Um it but it tends to be like you build an eval for a failure you've seen before a lot of times. So I have these prompt injection things that I'm trying to catch or something or um or or a failure in the way it's responded maybe to to something before. So they they tend to be this like you know u at least the LM as a judge is tends to be like this this thing you um preset up and then you can actually create evaluators for failure. Say you find this failure that's pretty common and happening all the time. I can create an eval so I can catch it next time. I just you think of it as like almost a an AI um assessment that's always running. Uh the other note is the element as a judge can run really at scale. Well, every you know I have customers who who lay you know layer element as a judge across um their full data set uh where where this tends to be like you know uh more periodic on a lot of data. So cool. Thank you.
