The OTel Collector Config Discipline

OTel collector configs sprawl. The discipline that keeps them maintainable and tested.

Version control

Collector configs in git. Reviewed like code. Deployed via CI.

No clicked-together configs in production.

Unit tests: send sample telemetry through the collector; verify processors and exporters do the right thing.

Linting: standard collector lint catches common errors before deploy.

Per-environment overlays. Base config + dev/staging/prod overrides.

Each overlay reviewed; no environment-specific magic that lives only in production.
