Sentry Performance Tuning
Prerequisites
- Performance monitoring enabled
- Transaction volume metrics available
- Critical paths identified
- Performance baseline established
Instructions
- Implement dynamic sampling with tracesSampler for endpoint-specific rates
- Configure environment-based sample rates (higher in dev, lower in prod)
- Remove unused integrations to reduce SDK overhead
- Limit breadcrumbs to reduce memory usage
- Use parameterized transaction names to avoid cardinality explosion
- Create spans only for meaningful slow operations
- Configure profile sampling sparingly for performance-critical endpoints
- Measure SDK initialization time and ongoing overhead
- Implement high-volume optimization with aggressive filtering
- Monitor SDK performance metrics and adjust configuration
Output
- Optimized sample rates configured
- SDK overhead minimized
- Transaction naming standardized
- Resource usage reduced
