Slow Honeycomb trace → Sentry error correlation → GitLab issue

When a Honeycomb trace blows past its latency budget, this workflow pulls the concurrent Sentry errors for the same service and time window and files a single enriched GitLab…

How it runs

The automated pipeline, trigger to output.

  • TriggerHoneycomb latency-budget trigger fires (webhook)Honeycomb
  • LogicConfirm trace exceeds budget and has a service name
  • ActionQuery Sentry for concurrent errors on that serviceSentrySentry
  • LogicJoin slow span breakdown with matching error fingerprints
  • OutputCreate enriched GitLab issue with trace + error contextGitLabGitLab

What it does

Turns a latency alarm into an actionable, pre-investigated ticket. A slow trace detected in Honeycomb is automatically cross-referenced with the Sentry errors that fired during the same span, and the combined evidence — slow trace ID, span breakdown, and matching exceptions — lands in one GitLab issue so an engineer starts from a hypothesis instead of a blank page.

When to use it

Use when p95/p99 latency spikes are common but tedious to triage, and you suspect they correlate with backend errors. Ideal for teams that already alert on Honeycomb triggers but waste time manually jumping to Sentry to find the related failures.

How it works

  1. 1A Honeycomb trigger fires when a trace exceeds the configured latency budget and posts the trace metadata via webhook.
  2. 2The workflow checks whether the trace duration clears the budget threshold and has a resolvable service name.
  3. 3It queries Sentry for unresolved errors on that service within the trace's start/end window.
  4. 4If matching errors exist, it joins the slow span breakdown with the top Sentry issues into one context block.
  5. 5A GitLab issue is created with the trace link, error fingerprints, and a suggested owner label.

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
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
