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.
Plan what to measure in web applications. Use when starting observability or prioritizing instrumentation.
Measure time from navigation to page fully loaded and interactive. Use when tracking SPA navigation, route changes, or slow page transitions.

Measure API requests and correlate with backend traces.
| Attribute | OTel Name | Purpose |
|---|---|---|
| Method | http.request.method | GET, POST, etc. |
| Status | http.response.status_code | Success/failure |
| URL | url.path | Endpoint (sanitized) |
| Duration | http.request.duration | Request time (ms) |
Using OTel naming now = easier migration later.
| Metric | Good | Acceptable | Poor |
|---|---|---|---|
| p50 | <200ms | <500ms | >500ms |
| p95 | <1s | <2s | >2s |
| Error rate | <0.1% | <1% | >1% |
| Don't | Why |
|---|---|
| Request bodies | PII risk |
| Auth headers | Security |
| Full response data | Size limits |
| User tokens | Security |
Do log: Request ID, sanitized path, status code, duration, error type.
