Learn how to enable Sentry release health, configure a Node.js app with a release tag, and verify that regressions are surfaced after deployment.
Learn how to diagnose and fix 'Event Dropped' or 'Rate Limit Reached' errors in Sentry using SDK sampling, ignore lists, and before_send filters to protect your quota.
Stop drowning in error alerts by using Sentry’s Release Health. Tag each deployment, view new‑issue spikes per release, and set alerts that focus on regressions. A Node.js example shows the exact SDK call and CI step needed.
Asynchronous Event Delivery and Process Termination Sentry SDKs utilize an internal queue and background worker to transmit events asynchronously, preventing the main application thread from blocking. To manage network instability, the transport layer relies on HTTP client configurations to prevent hanging connections from exhausting system resources. During
Goal: Determine how Sentry’s release health algorithm labels a release as healthy, degraded, or crashy when a deployment fails but no error events are reported for that release. Constraints: The health calculation uses a rolling window (default 24 hours) and requires a minimum traffic threshold before issuing a status. When no events are received, the algori
