AI root-cause draft: agent investigates a slow trace across Honeycomb + Sentry and drafts a GitLab issue

On a latency-budget breach, an investigative agent gathers the Honeycomb span breakdown and the concurrent Sentry errors, reasons about the likely root cause.

What it does

Does the first pass of root-cause analysis for you. Instead of a static join, an agent reads the slow trace's span breakdown, the correlated Sentry stack traces, and recent context, then writes a GitLab issue containing a plain-language hypothesis, the supporting evidence, and concrete next steps — leaving a human to confirm or correct.

When to use it

Use when latency regressions are nuanced and a raw error dump isn't enough to point at a cause. Best for teams who want a thoughtful starting hypothesis on the ticket, not just linked artifacts, and are comfortable reviewing agent-drafted analysis.

How it works

  1. 1A Honeycomb trigger fires on a trace that breaches its latency budget.
  2. 2The agent retrieves the full span breakdown for the slow trace from Honeycomb.
  3. 3It fetches the correlated Sentry errors and stack traces for the same service and window.
  4. 4The agent reasons over the combined signals to form a ranked root-cause hypothesis and next steps.
  5. 5It drafts a structured GitLab issue with the hypothesis, evidence links, and a confidence note for human review.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HoneycombDistributed traces and queries.
  2. 2
    Connect SentryErrors, performance, releases.
  3. 3
    Connect GitLabRepos, MRs, pipelines, registry.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
