This module provides automatic instrumentation for the [`net`](http://nodejs.org/dist/latest/docs/api/net.html) module, which may be loaded using the [`@opentelemetry/sdk-trace-node`](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-sdk-trace-node) package and is included in the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle.
|
|
|
|
If total installation size is not constrained, it is recommended to use the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle with [@opentelemetry/sdk-node](`https://www.npmjs.com/package/@opentelemetry/sdk-node`) for the most seamless instrumentation experience.
|
|
|
|
Supports both TCP and IPC connections.
|
|
|
|
Compatible with OpenTelemetry JS API and SDK `1.0+`.
|
|
|

const provider = new NodeTracerProvider();
|
|
provider.register();
|

|
|
| `net.peer.name` | Host name or the IPC file path |
|
|
| `net.peer.ip` (for TCP) | Remote address of the peer (dotted decimal for IPv4 or RFC5952 for IPv6) |
|
|
| `net.peer.port` (for TCP) | Remote port number |
|
|
| `net.host.ip` (for TCP) | Like net.peer.ip but for the host IP. Useful in case of a multi-IP host |
