How to check connection with OtlpExportProtocol.Grpc?

[makrushin-evgenii]

Hi. With OtlpExportProtocol.HttpProtobuf I can define HttpClientFactory to log requests results. For example:

internal class HttpClientDecorator: HttpClient
{
    public override HttpResponseMessage Send(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        var response = base.Send(request, cancellationToken);
        Console.WriteLine($"{DateTime.Now:T} Response: {response.StatusCode}");
        return response;
    }
}

using var loggerFactory = LoggerFactory.Create(builder => builder
    .AddOpenTelemetry(options => options
        .AddOtlpExporter(exporterOptions =>
        {
            exporterOptions.HttpClientFactory = () => new HttpClientDecorator();
            exporterOptions.Endpoint = new Uri("http://.../v1/logs");
            exporterOptions.Protocol = OtlpExportProtocol.HttpProtobuf;
        })
    )
);

var logger = loggerFactory.CreateLogger<Program>();
logger.LogInformation(string.Format("test: {0}", Guid.NewGuid()));

How can I check connection on client side with OtlpExportProtocol.Grpc?
