.Net Core的Log方式：Serilog+Kibana

阅读目录

1.Information
2.Error

前言

Serilog，支持对象，把log数据序列化成Json，好用方便，容易拓展。Github: https://github.com/handsomeyao77/serilog-sinks-elasticsearch

读取配置文件的

配置文件分为App.config和appsetting.json两种。
读取appsettings.json，主要是Web app 类型，首先在服务启动时要注入json文件：

读取配置:

配置App.config，高亮部分是必要的key：

读取配置：

当然，有时候可以Hard code，这里分享一种方式：

Serilog的常见类型

1.Information.

2.Debug.

3.Error.

因为LogEventBase作为基类，可以继承拓展一下。

public class LogEventBase
{
    [FieldOrder(0)]
    public LogEventType EventType { get; set; }

    [FieldOrder(1)]
    public string Role { get; set; }

    [FieldOrder(2)]
    public string RoleInstance { get; set; }

    [FieldOrder(3)]
    public string Ip { get; set; }

    [FieldOrder(4)]
    public int Port { get; set; }

    [FieldOrder(5)]
    public DateTime Timestamp => DateTime.UtcNow;

    [FieldOrder(6)]
    public string Message { get; set; }

    [FieldOrder(7)]
    public IActivity Activity { get; set; }

    [FieldOrder(8)]
    public string EnvironmentName => Environment.MachineName;
}

根据业务拓展：

public class LatencyEvent : LogEventBase
{
    [FieldOrder(9)]
    public long Latency { get; set; }

    [FieldOrder(10)]
    public string SearchId { get; set; }
}

public class SearchEvent : LogEventBase
{
    [FieldOrder(9)]
    public string SearchId { get; set; }
    [FieldOrder(10)]
    public string SearchString { get; set; }
}

public class LuisEvent : LogEventBase
{
    [FieldOrder(9)]
    public LuisResult LuisResult { get; set; }
}

public class ExceptionEvent : LogEventBase
{
    [FieldOrder(10)]
    public Exception Exception { get; set; }
}
