Sentry Go SDK
Official Go SDK for Sentry error monitoring and performance tracking. Captures panics, errors, and performance transactions in Go applications and reports them to Sentry's error tracking platform. Provides automatic panic recovery, context enrichment (user, request, tags), and performance monitoring with distributed tracing. Essential for production Go service observability.

🔒 Security
Events sent over HTTPS. DSN is project-specific but not secret — it appears in client-side code. PII scrubbing available. GDPR compliance tools provided.
⚡ Reliability
Best When
You're using Sentry for error monitoring and need to instrument Go services — the SDK provides automatic panic capture, context enrichment, and performance tracking.
Avoid When
You want vendor-neutral observability (use OpenTelemetry) or need metrics/logs (use Prometheus + Loki).
Use Cases
- • Automatically capture and report panics and unhandled errors in Go services to Sentry for production error tracking
- • Add structured context (user ID, request ID, environment tags) to Go error reports for faster debugging
- • Monitor Go service performance with Sentry transactions and spans for APM-style visibility
- • Track agent execution errors and failures with automatic stack traces and breadcrumb trail context
- • Integrate with net/http, gin, echo, and other Go frameworks using Sentry SDK middleware for automatic request instrumentation
Not For
- • Teams not using Sentry — use opentelemetry-go for vendor-neutral observability with any backend
- • Metrics and time-series data — Sentry focuses on errors and transactions, not infrastructure metrics; use Prometheus
- • Log aggregation — Sentry captures errors, not logs; use Loki or ELK for log aggregation
Interface
Authentication
Sentry DSN (Data Source Name) contains project-specific API key. DSN is typically set via SENTRY_DSN environment variable.
Pricing
Free tier sufficient for small projects. Pricing scales with event volume. Self-hosted option available (Apache 2.0).
Agent Metadata
Known Gotchas
- ⚠ sentry.Init() must be called before any sentry.Capture* calls — calling capture functions before init silently drops events
- ⚠ sentry.Flush() must be called before process exit — the SDK sends events asynchronously; exiting without flush drops buffered events
- ⚠ Panic recovery requires explicit sentry.Recover() in deferred functions or use sentrynegroni/sentryhttp middleware for automatic HTTP panic recovery
- ⚠ Hub/Scope pattern in Go SDK differs from other Sentry SDKs — use sentry.WithScope() for request-scoped context rather than global scope
- ⚠ Performance tracing requires manually creating transactions and spans — not automatic for all Go frameworks; use contrib packages for gin/echo/chi
- ⚠ Event sampling rates should be configured for high-throughput services — sending all events to Sentry can hit plan limits quickly
