# Official sources

Use this reference only when you need source grounding for GCP observability service behavior or the detailed source list.

## Google Cloud documentation

Use these as starting points, not as proof of the user's live GCP state:
- https://cloud.google.com/monitoring/docs/monitoring-overview
- https://cloud.google.com/logging/docs/overview
- https://cloud.google.com/error-reporting/docs
- https://cloud.google.com/trace/docs
- https://cloud.google.com/monitoring/slos/slo-monitoring
- https://cloud.google.com/logging/docs/routing/overview
- https://cloud.google.com/monitoring/alerts/using-alerting-ui
- https://cloud.google.com/logging/docs/logs-based-metrics/overview

## Grounding rule

Official documentation explains GCP observability service behavior. It does not prove the user's current project, alerting state, log sink configuration, IAM boundary, or operational posture. Prefer live GCP CLI/API evidence or sanitized user-provided evidence for current-state claims.
