ConfigureServices下添加：

#region AppMetrics添加

            bool isOpenMetrics = Convert.ToBoolean(Configuration["AppMetrics:IsOpen"]);
            if (isOpenMetrics)
            {
                string database = Configuration["AppMetrics:DatabaseName"];
                string connStr = Configuration["AppMetrics:ConnectionString"];
                string app = Configuration["AppMetrics:App"];
                string env = Configuration["AppMetrics:Env"];
                string username = Configuration["AppMetrics:UserName"];
                string password = Configuration["AppMetrics:Password"];

                var uri = new Uri(connStr);
                var metrics = AppMetrics.CreateDefaultBuilder().Configuration.Configure(options =>
                {
                    options.AddAppTag(app);
                    options.AddEnvTag(env);
                }).Report.ToInfluxDb(options =>
                {
                    options.InfluxDb.BaseUri = uri;
                    options.InfluxDb.Database = database;

                    options.InfluxDb.Password = password;
                    options.HttpPolicy.BackoffPeriod = TimeSpan.FromSeconds(30);

                    options.FlushInterval = TimeSpan.FromSeconds(5);
                }).Build();

                services.AddMetrics(metrics);
                services.AddMetricsReportingHostedService();
                //services.AddMetricsReportScheduler();
