A lot of teams are using AI in some form to reduce their on-call burden. You may be pasting logs into Cursor, or using Claude Code with Datadog’s MCP server to help debug. What we’ve seen is that autonomous root cause analysis is a hard problem for AI. This shows up in benchmarks - Claude Opus 4.6 is currently at 36% accuracy on the OpenRCA dataset, in contrast to coding tasks.
There are three main reasons for this: (1) Telemetry data volume can drown the model in noise; (2) Data interpretation / reasoning is enterprise context dependent; (3) On-call is a time-constrained, high-stakes problem, with little room for AI to explore during investigation time. Errors that send the user down the wrong path are not easily forgiven.
At Relvy, we are tackling these problems by building specialized tools for telemetry data analysis. Our tools can detect anomalies and identify problem slices from dense time series data, do log pattern search, and reason about span trees, all without overwhelming the agent context.
Anchoring the agent around runbooks leads to less agentic exploration and more deterministic steps that reflect the most useful steps that an experienced engineer would take. That results in faster analysis, and less cognitive load on engineers to review and understand what the AI did.
How it works: Relvy is installed on a local machine via docker-compose (or via helm charts, or sign up on our cloud), connect your stack (observability and code), create your first runbook and have Relvy investigate a recent alert.
Each investigation is presented as a notebook in our web UI, with data visualizations that help engineers verify and build trust with the AI. From there on, Relvy can be configured to automatically respond to alerts from Slack
Some example runbook steps that Relvy automates: - Check so-and-so dashboard, see if the errors are isolated to a specific shard. - Check if there’s a throughput surge on the APM page, and if so, is it from a few IPs? - Check recent commits to see if anything changed for this endpoint.
You can also configure AWS CLI commands that Relvy can run to automate mitigation actions, with human approval.
A little bit about us - We did YC back in fall 2024. We started our journey experimenting with continuous log monitoring with small language models - that was too slow. We then invested deeply into solving root cause analysis effectively, and our product today is the result of about a year of work with our early customers.
Give us a try today. Happy to hear feedback, or about how you are tackling on-call burden at your company. Appreciate any comments or suggestions!
1) Greater accuracy with our specialized tools: Most MCP tools allow agents to query data, or run *ql queries - this overwhelms context windows given the scale of telemetry data. Raw data is also not great for reasoning - we’ve designed our tools to ensure that models get data in the right format, enriched with statistical summaries, baselines, and correlation data, so LLMs can focus on reasoning.
2) Product UX: You’ll also find that text based outputs from general purpose agents are not sufficient for this task - our notebook UX offers a great way to visualize the underlying data so you can review and build trust with the AI.
I have had incredible success debugging issues by just hooking up Datadog MCP and giving agents access to it. Claude/cursor don't seem to have any issues pulling in the raw data they need in amounts that don't overload their context.
Do you consider this a tool to be used in addition to something like cursor cloud agents or to replace it?
Re: diffentiation - yes, faster, more accurate and more consistent. Partially because of better tools and UX, and partially because we anchor on runbooks. On-call engineers can quickly map out that the AI ran so-and-so steps, and here's what it found for each, and here's the time series graph that supports this.
Interesting that you have had great success with Datadog MCP. Do you mainly look at logs?
Imo, this is not what users want. They want extension to their agent. If a project tells me I have to use their interface or agentic setup, it's 95% not going to happen. Consider how many SaaS tools we already have to deal with, that many agents is not desirable, they all have their little quirks and take time to "get to know"
Instead, build extensions, skills, and subagents that fit into my agentic workflow and tooling. This will also simplify what you need to do, so you can focus on your core competency. For example, you should be able to create a chat participant in VS Code / Copilot, and take advantage of the native notebook and diff rendering, sharing the MCPs (et al) the user already has for their agents for their internal systems.
Yes, there’s definitely friction there. It may be that the right form factor is that you trigger Relvy’s debugging agent via Claude code / Cursor .
Our early users are heavy on needing to look at the raw data to be able to review the AI RCA, so a standalone set up makes sense. Also, the dominant usage pattern is background agentic execution triggered by alerts, and not manual.
Runbooks are great and all, but actions need to be taken and I'm not going to give all the vendor interfaces to the internal systems. They can be subagents in my system which already has the tools and permission gates needed, access to code and git for IaC changes, etc...
It seems like the way to go now, it's easier to get moving and show off an experience and the vision, but it's definitely not the operational way in prod for a lot of reasons, security being a paramount one.
I also do not discount that your SaaS can be easily replaced by an open sourced subagent team in the next couple of years.
With the docker images that we offer, in theory, people can re-run the benchmark themselves with our agent. But we should document and make that easier.
At the end of it, you really would have to evaluate on your own production alerts. Hopefully the easy install + set up helps.
