Datadog — From Zero to Hero
A standalone, developer-focused course on Datadog — the unified observability platform. From the Agent and unified service tagging to metrics, log management, APM, and the correlation model that ties them into one view per service — taught through real Agent config, DogStatsD, and Terraform. Every layered detail (ingestion vs. retention sampling, exclusion filters vs. archives) is verified against current docs.

How this course works
Section titled “How this course works”Layered pipelines, not one dial
Metrics, logs, and traces are separate pipelines, each with its own ingestion, retention, and cost controls — this course teaches every layer instead of treating “sampling” or “retention” as one setting.
Current behavior, verified
Written against current Datadog behavior and checked against the official docs via context7 — including the split between log ingestion and indexing, and APM’s ingestion-vs-retention-filter distinction that a lot of tutorials collapse into one.
One tag triple, three pipelines
Not just “add some tags” but the full picture: how env/service/version — unified service tagging — let you pivot between a service’s metrics, traces, and logs instead of hunting through three disconnected tools.
