a simple log center

desc

支持服务器端的日志过滤

• 1 类库中，声明了日志的别名[ProviderAlias("RemoteLogCenter")]
• 2 客户端，通过appsettings.json中配置节RemoteLogCenter，来控制发往远端的日志输出
• 3 可以通过RemoteHubReporterConfig.Enabled来控制是否停用

structure

• 工具库： LogCenter.Common

• 演示客户端：LogCenter.Client

• 日志服务：LogCenter.Web

• 封装组件：

  • C#: LogCenter.Common.dll (Server + Client)
  • JS: common.log.logHubHelper.js (Server + Client)

• Logger类型

  • Client端发送日志，使用的Logger类型是："LogCenter.Client.RemoteLogger", 原始的日志类型，存储在其Category属性中
  • Server端接受Hub日志，使用的Logger的类型是："LogCenter.Server.NetCoreLogHelper", 原始的日志类型，体现在message的描述中 => logHelper.Log(args.Category + " " + args.Message, args.Level)

Client端的LogLevel设置：appsettings.json

通过调整Client端的appsettings.json中的RemoteLogCenter设置，可以控制发往远端的日志级别 例如"Microsoft": "Information" => "Microsoft": "Error"，可大大降低发送到远端的日志数量

{
    "RemoteLogCenter": {
      "LogLevel": {
        "Default": "Information",
        "LogCenter": "Warning",
        "System": "Error",
        "Microsoft": "Error"
      }
    }
}

Server端的LogLevel设置：nlog.json

  <rules>
    <!--All logs, including from Microsoft-->
    <logger name="*" minlevel="Trace" writeTo="all" />
    <!--Skip non-critical Microsoft logs and so log only own logs-->
    <logger name="Microsoft.*" maxlevel="Info" final="true" />
    <!-- BlackHole without writeTo -->
    <logger name="LogCenter.*" minlevel="Debug" writeTo="application" />
  </rules>

multi client log support

Client端设置：appsettings.json

  "RemoteHubReporter": {
    "ClientId" : "[DemoClient]", 
    "Enabled": true,
    "HubUri": "ws://192.168.1.182:8040/hubs/logHub",
    "MaxTryCount": 3
  },

• RemoteLoggerProvider.ClientId => RemoteHubReporter.ClientId
• RemoteLogger.Log()
• LogHub.CallServerLog()

工具日志和远端日志

工具日志和远端日志两部分设计，完全不相关，注意避免混淆

• LogHelper
  • ILogHelper <- LogHelper
  • ILogHelper <- LogHelperAdapter(Logger logger)
• RemoteLoggerProvider
  • ILoggerProvider <- RemoteLoggerProvider

todo

• log list view
• download log in log list view
• view log in log list view
