* Prerequisite to run this example:
|
|
* Set up an OpenTelemetry Collector to run on local docker.
|
|
*
|
|
* Open a terminal window at the examples/Console/ directory and
|
|
* launch the OpenTelemetry Collector with an OTLP receiver, by running:
|
|
*
|
|
* - On Unix based systems use:
|
|
* docker run --rm -it -p 4317:4317 -p 4318:4318 -v $(pwd):/cfg otel/opentelemetry-collector:0.48.0 --config=/cfg/otlp-collector-example/config.yaml
|
|
*
|
|
* - On Windows use:
|
|
* docker run --rm -it -p 4317:4317 -p 4318:4318 -v "%cd%":/cfg otel/opentelemetry-collector:0.48.0 --config=/cfg/otlp-collector-example/config.yaml
|
|
*
|
|
* Open another terminal window at the examples/Console/ directory and
|
|
* launch the OTLP example by running:
|
|
*
|
|
* dotnet run logs --useExporter otlp -e http://localhost:4317
|
|
*
|
|
* The OpenTelemetry Collector will output all received logs to the stdout of its terminal.
