- ### Replace SignalFx metrics with OpenTelemetry metrics

SignalFx metrics SDK has been removed and replaced with OpenTelemetry Metrics SDKs.
The internal SignalFx client is no longer available to users, if you have been using custom metrics with the SignalFx client provided by Splunk OpenTelemetry JS distribution, see the [Migrate from the SignalFx Tracing Library for NodeJS](https://quickdraw.splunk.com/redirect/?product=Observability&version=current&location=nodejs.application.migrate) in the official documentation.

Runtime metric names are now using [OpenTelemetry conventions](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/semantic_conventions/runtime-environment-metrics.md), the following is a list of changed metric names:

| SignalFx (no longer available) | OpenTelemetry |
| ------------------------------ | ------------------------------------------- |
| `nodejs.memory.heap.total` | `process.runtime.nodejs.memory.heap.total` |
| `nodejs.memory.heap.used` | `process.runtime.nodejs.memory.heap.used` |
| `nodejs.memory.rss` | `process.runtime.nodejs.memory.rss` |
| `nodejs.memory.gc.size` | `process.runtime.nodejs.memory.gc.size` |
| `nodejs.memory.gc.pause` | `process.runtime.nodejs.memory.gc.pause` |
| `nodejs.memory.gc.count` | `process.runtime.nodejs.memory.gc.count` |
| `nodejs.memory.gc.pause` | `process.runtime.nodejs.memory.gc.pause` |
| `nodejs.memory.gc.count` | `process.runtime.nodejs.memory.gc.count` |
| `nodejs.event_loop.lag.max` | `process.runtime.nodejs.event_loop.lag.max` |
| `nodejs.event_loop.lag.min` | `process.runtime.nodejs.event_loop.lag.min` |
