本文介绍如何使用Serilog进行日志记录，并将其与Elasticsearch集成来实现高效的日志管理和检索。主要内容包括配置Serilog以不同级别记录日志到文件及控制台，以及如何配置Elasticsearch作为日志接收端。

1.通过nuget安装以下包

2.在program.cs中加入下面代码

感觉这个 DetectElasticsearchVersion = true,代码必须写，否则无法写入ES



string Dir1 = DateTime.Now.ToString("yyyy-MM-dd");
string Dir2 = DateTime.Now.ToString("yyyy-MM-dd HH");

//LogEvent.
Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .MinimumLevel.Override("Microsoft", LogEventLevel.Information)
    .ReadFrom.Configuration(new ConfigurationBuilder()
    .AddJsonFile("appsettings.json")
    .Build())
    .Enrich.FromLogContext()
                    .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://192.168.1.104:9200/"))
                    {
                        BufferBaseFilename = "./logs/buffer",
                        IndexFormat = "muxue-api-{0:yyyy.MM}",
                        EmitEventFailure = EmitEventFailureHandling.RaiseCallback,
                        FailureCallback = e => Debug.WriteLine($"unable to ------{e.MessageTemplate}"),
                        AutoRegisterTemplate = true,
                        DetectElasticsearchVersion = true,

                        OverwriteTemplate = true,
                       // TemplateName = yourTemplateName,
                        AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv7,
                        TypeName = null,
                        BatchAction = ElasticOpType.Create
                        // AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv7, 
                    })
    //  .WriteTo.Async(c => c.File(Path.Combine(AppDomain.CurrentDomain.BaseDirectory + $"/Slog/{Dir1}/{Dir2}{typeof(LevelAlias).FullName}/", $"log.txt"), rollingInterval: RollingInterval.Hour))

    // .WriteTo.Async(path: "error.log", restrictedToMinimumLevel: LogEventLevel.Error, rollingInterval: RollingInterval.Day)
    // .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://192.168.1.104:9200/MyES")))
    .CreateLogger();
