AI AGENTS

Datadog Bill Spike Attribution Agent

When a daily Datadog cost check detects a spend jump, an agent attributes the increase to the specific services and metric types driving it and posts a ranked breakdown to Slack.

What it does

Watches your Datadog usage spend day over day. When total cost rises beyond a set threshold, an agent pulls the usage attribution data, ranks which services and product lines (custom metrics, ingested logs, indexed spans, hosts) caused the jump, and posts a plain-English breakdown to Slack so the on-call owner knows exactly where the money went.

When to use it

Run it when your Datadog bill surprises you mid-month and nobody can say which team or service is responsible. Ideal for platform and FinOps teams who want an automatic first-pass diagnosis instead of digging through the usage dashboard by hand.

How it works

  1. 1A daily schedule fires the workflow each morning.
  2. 2The agent queries Datadog's usage and cost-attribution endpoints for yesterday and the prior 7-day baseline.
  3. 3A logic step checks whether the day-over-day increase exceeds the configured percentage threshold; if not, it exits quietly.
  4. 4On a spike, the agent computes per-service and per-product deltas and ranks the top contributors.
  5. 5It drafts a readable summary explaining the largest drivers and likely cause.
  6. 6The summary posts to a Slack channel with the ranked table and dollar deltas.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect DatadogMetrics, traces, log search.
  2. 2
    Connect OpenAIModels, embeddings, files.
  3. 3
    Connect SlackChannels, DMs, threads, mentions.
  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.
