Learning Guidance

Objectives

Link monitor IDs to service ownership and escalation defaults.
Differentiate noisy alerts from customer-impacting patterns.
Build first-pass investigation checkpoints per monitor family.

Evidence To Capture

Primary monitor and related monitors identified.
Initial owner-routing hypothesis documented.

Source Artifacts

Internal source references are available for maintainers but are not exposed in deployed environments.

Field Evidence

Real incidents related to what you're learning.

Key Takeaways

Payments incidents: payments team first, then SRE if infra symptoms present.
Order flow incidents: order-delivery first, then payments/cart based on failed step.
Authentication incidents: customer-auth first, security review if bot patterns detected.
RDS or cluster health incidents: SRE first, then impacted product teams.

Overview

Priority set for onboarding comes from observability-audit/monitors/common-monitors.md and detailed monitor YAML files.
