Datadog → Elastic · Cost & Unified O11Y
From Datadog · Challenge 1 · ~15 min

Datadog’s price forces coverage gaps.

Customer value: Stop paying Datadog to store metrics you had to drop — move to Elastic Serverless with full coverage at a lower bill.

Datadog bills custom metrics aggressively, so teams drop series, sample metrics, and exclude environments just to keep the invoice down — then miss production blind spots. On the TCO worksheet, Datadog is ~$12.6K/mo (metrics alone ~$3.8K) vs Elastic Serverless ~$1.3K (metrics ~$0.9K). This lab moves the backend: audit what you are not sending to Datadog anymore, then Drop noise at ingest on Elastic instead of paying to store it.

PRICE

Custom metrics tax

High-cardinality tags and debug routes inflate the bill — every series you keep is a SKU.

COVERAGE

Pay to shrink observability

Teams drop labels, shorten retention, and exclude services to control Datadog spend — gaps follow.

MOVE TO

Elastic Serverless

Drop at ingest, keep the signals you need — one project, worksheet-backed savings.

In the lab: Streams → metrics-generic.otel-default → name one metric you stopped sending to Datadog to save money.

Overrun control — Drop before the bill, not after.

On Datadog a cardinality spike is an invoice surprise. On Elastic, Streams Drop caps what you store first.

On the Datadog worksheet, Datadog lands near ~$12.6K/mo while Elastic Serverless is ~$1.3K (89% cheaper) and ECH ~$0.6K. Metrics alone: Datadog ~$3.8K vs Serverless ~$0.9K (~4×). In the lab: Drop /debug/pprof, open Horizon — Your savings vs Datadog, then open the calc.

OVERRUN

Pay-then-filter

Datadog custom-metrics pricing bills the spike first. Filtering later doesn’t undo the invoice.

CONTROL

Streams Drop

Cut /debug/pprof and cardinality before ingest — noise never stored, bill stays predictable.

In the lab: Drop + lifecycle → Your savings vs Datadog board → open the TCO calc → say “overrun control.”

Investigate on metrics — savings board + migrated sample.

Same Streams pipeline behind both boards — no APM/traces required in this lab.

You already saw Datadog at ~$12.6K/mo vs Elastic Serverless ~$1.3K on the TCO worksheet (metrics alone ~$3.8K vs ~$0.9K). Now open Horizon — Your savings vs Datadog, Sample: Service Basics, and Horizon — Dashboard sprawl (hundreds of Datadog boards; custom metrics billed even if unused).

SAVINGS

Your savings board

Quantify Drop + lifecycle — what Datadog would still bill as custom metrics.

MIGRATE

Sample: Service Basics

Datadog export → live request/error metrics on Horizon without a rewrite project.

STREAM

Same pipeline

metrics-generic.otel-default — one stream, overrun control from Challenge 2.

SPRAWL

Boards → indexes

Datadog dashboard sprawl: Elastic shows which boards query which indexes, and alerts if a schema change would blank a widget.

In the lab: Dashboards → Sample: Service Basics → Horizon — Dashboard sprawl → Streams → one metrics savings sentence.

Agent Builder vs Bits — AI on the data you kept.

Bits investigates Datadog’s billed plane. Agent Builder investigates your Serverless project after Drop.

Open Agent Builder, ask about Horizon metrics on metrics-generic.otel-default, and leave with one clear contrast: AI that runs on metrics you chose to keep — not on the invoice you’re trying to leave.

BITS

On Datadog’s bill

Bits AI / Bits Agent Builder are strong — and still tied to metrics already stored on Datadog.

AGENT BUILDER

On your savings stack

Same project as Streams Drop + metrics dashboards — Observability agent + skills, live on Serverless today.

TAKEAWAY

One sentence

“We Drop noise first, then Agent Builder investigates the cleaner, cheaper metrics in one project.”

In the lab: Agent Builder → Horizon metrics prompt → name Bits vs Agent Builder contrast.
