What is an analogue of the publishing-to-pushgateway mechanism class in opentelemetry or another mechanism for sending metrics from a Windows application to the Web application (which collects all metrics by application names and sends them to Prometheus)? Both applications are hosted in docker containers.

It’s interesting to use this pattern in the example code for sending and receiving metrics.
I don’t fully understand the work of an open-telemetry-collector, but I think it performs other functions.

public class Program
{
    private static readonly ActivitySource MyActivitySource = new("OpenTelemetry.Demo.Exemplar");

    public static void Main()
    {
        var tracerProvider = Sdk.CreateTracerProviderBuilder()
            .AddSource("OpenTelemetry.Demo.Exemplar")
            .AddOtlpExporter()
            .Build();

        var meterProvider = Sdk.CreateMeterProviderBuilder()
            .AddMeter("OpenTelemetry.Demo.Exemplar")
            .AddOtlpExporter((exporterOptions, metricReaderOptions) =>
            {
                exporterOptions.Endpoint = new Uri("http://localhost:9090/api/v1/otlp/v1/metrics");
                exporterOptions.Protocol = OtlpExportProtocol.HttpProtobuf;
            })
            .Build();
