Sentry
A self-hosted error tracking and monitoring product.
- Sentry: the DSN is public, the auth token is secret
The DSN is a public ingest address that belongs in SDK init code. The auth token is a secret that belongs in CI. Mixing them up either breaks uploads or leaks credentials into client bundles. Not the full reference manual.
- Sentry Express: skip the old two-middleware dance
Modern @sentry/node captures Express errors automatically through expressIntegration. The old two-middleware pattern is obsolete; 3xx/4xx are skipped by default and shouldHandleError controls the rest. Not the full reference manual.
- Sentry Laravel queues: per-job sample rates for noisy workers
Queued jobs fail differently from web requests: they retry, they run long, and they can dominate trace volume. Per-job sample rates and failed-job capture in Laravel. Not the full reference manual.
- Sentry Python logs: breadcrumbs, Logs product, and before_send_log
The Python SDK has three log paths: breadcrumbs from loggers (default), the Logs product, and before_send_log to filter. Which to use and how to keep log volume from eating quota. Not the full reference manual.
