基于 SOC 职业分类
Instrument API requests with spans and distributed tracing. Use when tracking request latency or debugging API issues.
Monitor JavaScript bundle size and execution performance. Use when tracking bundle size, identifying large chunks, or optimizing load performance.
Measure and optimize Core Web Vitals (LCP, INP, CLS). Use when implementing CWV tracking or debugging performance.
Set up error tracking with actionable context. Use when configuring error capture or error boundaries.
Measure SSR hydration timing and issues. Use when tracking hydration performance, debugging hydration mismatches, or optimizing SSR/SSG applications.
Measure time from navigation to page fully loaded and interactive. Use when tracking SPA navigation, route changes, or slow page transitions.

Strategic guidance for what to measure in web applications.
For each user job, ask:
| Tier | Focus | Priority |
|---|---|---|
| 1 | Errors + source maps | P0 - Day 1 |
| 2 | Core Web Vitals | P0 - Day 1 |
| 3 | User context + breadcrumbs | P0 - Week 1 |
| 4 | Route transitions + API tracing | P1 - Week 2 |
| 5 | Business metrics + synthetic tests | P2 - Month 1 |
| Metric | Good | Needs Improvement | Poor |
|---|---|---|---|
| LCP | ≤2.5s | ≤4.0s | >4.0s |
| INP | ≤200ms | ≤500ms | >500ms |
| CLS | ≤0.1 | ≤0.25 | >0.25 |
