…google-cloud-serverless, skip for bun Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…ener Fixes the beforeExit listener to fire on every invocation in serverless warm starts (e.g. AWS Lambda). Also properly removes the old listener on re-init to avoid accumulation. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Framework wrappers (SvelteKit, TanStack, etc.) already call flushIfServerless after each request handler. The beforeExit flush was redundant and introduced an infinite loop risk since Node.js re-emits beforeExit after async work completes. Metrics are sent by the periodic interval or the existing SDK flush infrastructure. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…s in integration tests ArrayContaining items are matched with strict equals (subsetEquality is not propagated), so extra attributes like sentry.timestamp.sequence and server.address caused all arrayContaining matches to fail. Wrapping with expect.objectContaining allows extra keys. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Mirrors nodeRuntimeMetricsIntegration but adapted for Bun: - Same CPU, memory, ELU, and uptime metrics - No event loop delay percentiles (monitorEventLoopDelay not available in Bun) - ELU wrapped in try/catch for forward compatibility with older Bun versions - Metrics use bun.runtime.* prefix and auto.bun.runtime_metrics origin - BunRuntimeMetricsOptions reuses NodeRuntimeMetricsOptions collect shape (minus the unsupported eventLoopDelay* flags) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds node-integration-tests scenarios that exercise the bun integration using @sentry/node for init (bunRuntimeMetricsIntegration is Node-compatible since it only uses perf_hooks and process.*). Four test scenarios: - default metrics shape (6 metrics with correct attributes/units) - opt-in metrics not emitted by default - all metrics when cpuTime + memExternal opted in - opt-out leaves only memory metrics Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

| ### Important Changes | ||
| - **feat(node, bun): Add runtime metrics integrations for Node.js and Bun ([#19923](https://github.com/getsentry/sentry-javascript/pull/19923), [#19979](https://github.com/getsentry/sentry-javascript/pull/19979))** | ||
| New `nodeRuntimeMetricsIntegration` and `bunRuntimeMetricsIntegration` automatically collect runtime health metrics and send them to Sentry on a configurable interval (default: 30s). Collected metrics include memory (RSS, heap used/total), CPU utilization, event loop utilization, and process uptime. Node additionally collects event loop delay percentiles (p50, p99). Extra metrics like CPU time and external memory are available as opt-in. | ||
| ```ts | ||
| // Node.js | ||
| import * as Sentry from '@sentry/node'; | ||
| Sentry.init({ | ||
| dsn: '...', | ||
| integrations: [Sentry.nodeRuntimeMetricsIntegration()], | ||
| }); |

There was a problem hiding this comment.
I added the note for node again bc this was somehow lost in the gitflow merge (?)

Document the new bunRuntimeMetricsIntegration for collecting Bun runtime health metrics (memory, CPU, event loop, uptime). Ref: getsentry/sentry-javascript#19979 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Explicitly pick the metrics available in Bun rather than omitting Node-only fields, so new Node metrics don't silently leak into Bun. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
