Error Reporting / Trace / Profiler

Error Reporting

What / why

• Scans Cloud Logging entries → aggregate & de-dupe exceptions (stack trace 기반).
• Real-time grouping, dashboard, instant notifications (email, mobile app, Slack, webhooks).

Hard constraints (중요!)

• 분석 가능한 로그 = global region의 Cloud Logging bucket에 저장된 것만.
• Same source/destination project, CMEK disabled.
• Regionalized buckets, 다른 프로젝트로 라우팅, CMEK enabled → 수집/분석 불가.

Language & platform

• Go/Java/Node.js/PHP/Python/Ruby/.NET + via client libs, REST, 또는 Cloud Logging.
• Aggregates errors from: App Engine (std/flex), Cloud Run, Cloud Functions, Apps Script, GKE, Compute Engine, Amazon EC2.

Setup (Node.js quick path)

1. Enable Error Reporting API.
2. Service account: Error Reporting Writer role.
3. Install & init client, then report(); options로 behavior 조정, message builder로 필드 커스터마이즈.

Env specifics

• Auto-enabled: App Engine std/flex, Cloud Run, Cloud Functions, Apps Script.
• GKE: cluster 생성 시 cloud-platform scope 추가.
• Compute Engine: 사용 SA에 Writer role.
