Administrators need to know whether the sentry upgrade command produces any backup artifacts before applying schema migrations and code changes. The official documentation advises taking a manual PostgreSQL dump and copying configuration files, yet the upgrade tool does not enforce this step and offers no automated rollback if a migration fails mid‑process.
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
I'm designing a team workflow around Sentry's Discover query builder and need to understand the boundaries of its filter persistence before committing to it. My goal is to share a standardized set of saved filters (by status, logger, and culprit) across an entire engineering team without each member rebuilding them manually. From what I can tell, Discover fi
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
Goal Determine the default HTTP connection pool size used by the major Sentry SDKs and the documented behavior when that pool is exhausted. Constraints Pool configuration is SDK‑specific (e.g., OkHttp for Java, urllib3 for Python, Netty for JavaScript) and not centrally managed. SDK documentation lists tuning parameters but does not expose built‑in metrics f
The goal is to select a credential type for automated CI/CD pipelines that enforces least‑privilege access while preserving clear auditability and simple credential rotation. Sentry offers organization‑level auth tokens that can be scoped to individual projects, and internal integration tokens that are created per service with customizable scopes. The unreso
Goal Choose a safe way to exercise Sentry SDK delivery wiring in tests without a production DSN or outbound access to Sentry. Constraints When no usable DSN is supplied, many Sentry SDKs initialize successfully but treat capture as a no-op, so a passing test does not prove event delivery. The exact path depends on SDK major and runtime, and defaults for enab
Background Sentry’s Transaction Sampling feature was introduced in SDK version 6.0.0. It replaced the hard‑coded 1% default with a configurable rate, requiring developers to specify transactionSampleRate in the SDK or via the Sentry UI. Legacy SDKs (pre‑6.0.0) retain the 1% default if the new key is absent. Constraints New projects must explicitly set transa
When a Sentry server replies with HTTP 429, the client SDK emits an "Event dropped by rate limiter" warning. The response usually contains a Retry-After header that indicates how long the client should pause before sending further events. Some language bindings (e.g., JavaScript) parse and respect this header, while others (e.g., Python in older releases) ig
