| # OpenTelemetry Exporters | ||
|
|
||
| Once the OpenTelemetry SDK has created and processed telemetry, it needs to be exported. | ||
| This package contains exporters for this purpose. | ||
|
|
||
| ## Exporter Packages | ||
|
|
||
| The following exporter packages are provided with the following OpenTelemetry signal support. | ||
|
|
||
| | Exporter Package | Metrics | Traces | | ||
