“请确保OpenTelemetry是通过Steeltoe扩展方法配置的”错误？

Question

每次调用端点/执行器/prometheus时，我都会得到这个错误。我不知道会有什么问题？这是初始化代码(我确信openTelemetryEndpoint变量有一个值)：

            builder.Services.AddAllActuators();
            builder.Services.AddPrometheusActuator();

            // OpenTelemetry configuration
            var openTelemetryServiceName = Environment.GetEnvironmentVariable("OTEL_SERVICE_NAME");
            var openTelemetryEndpoint = Environment.GetEnvironmentVariable("OTEL_EXPORTER_OTLP_TRACES_ENDPOINT");

            if (!string.IsNullOrWhiteSpace(openTelemetryEndpoint))
            {
                // Configure metrics
                builder.Services.AddOpenTelemetryMetrics(b =>
                {
                    b.AddHttpClientInstrumentation();
                    b.AddAspNetCoreInstrumentation();
                    b.AddMeter(openTelemetryServiceName + "-metrics");
                    b.AddOtlpExporter(options =>
                    {
                        options.Endpoint = new Uri(openTelemetryEndpoint);
                        options.Protocol = OpenTelemetry.Exporter.OtlpExportProtocol.Grpc;
                    });
                });

                // Configure tracing
                builder.Services.AddOpenTelemetryTracing(b =>
                {
                    b.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(openTelemetryServiceName));
                    b.AddHttpClientInstrumentation();
                    b.AddAspNetCoreInstrumentation();
                    b.AddSource(openTelemetryServiceName + "-activity-source");
                    b.AddOtlpExporter(options =>
                    {
                        options.Endpoint = new Uri(openTelemetryEndpoint);
                        options.Protocol = OpenTelemetry.Exporter.OtlpExportProtocol.Grpc;
                    });
                });

                // Configure logging
                builder.Logging.AddOpenTelemetry(b =>
                {
                    b.IncludeFormattedMessage = true;
                    b.IncludeScopes = true;
                    b.ParseStateValues = true;
                    b.AddOtlpExporter(options =>
                    {
                        options.Endpoint = new Uri(openTelemetryEndpoint);
                        options.Protocol = OpenTelemetry.Exporter.OtlpExportProtocol.Grpc;
                    });
                    b.AddConsoleExporter();
                });
            }

Marcelo，错误消息是，您需要使用Metrics的Steeltoe扩展：‘`AddOpenTelemetryMetricsForSteeltoe来获得所需的功能。Steeltoe内部使用OpentelemetryMetrics作为自己的出口产品，例如/Metrics、/Prometheus和Wavefront出口商。如果希望添加OLTP导出程序，则还必须使用扩展方法来添加附加配置。
