Honeycomb Event-Volume Spike PagerDuty Cost Guardrail

Watches Honeycomb event ingest in near-real-time and pages on-call via PagerDuty when a single dataset's volume breaches a daily budget.

How it runs

The automated pipeline, trigger to output.

  • OutputOpen PagerDuty incident with overage and offendersPagerDutyPagerDuty

What it does

This workflow checks Honeycomb ingest volume on a tight interval, projects each dataset's daily event count against a per-dataset budget, and when a dataset is on pace to blow its budget it triggers a PagerDuty incident. The incident body names the specific high-cardinality columns contributing most to the spike so on-call can act immediately.

When to use it

Use it when an accidental log-level change or a chatty new field can quietly 10x your Honeycomb bill in hours. This is the real-time guardrail that catches cost runaways before they compound overnight.

How it works

  1. 1A short-interval schedule triggers the check.
  2. 2Query Honeycomb for current ingest rate and per-column contribution per dataset.
  3. 3Logic projects end-of-day volume and compares it to each dataset's budget.
  4. 4If a dataset is over pace, identify the top contributing high-cardinality columns.
  5. 5Open a PagerDuty incident with the dataset, projected overage, and offending columns.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HoneycombDistributed traces and queries.
  2. 2
    Connect PagerDutyIncidents, on-call, escalations.
  3. 3
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
