• ">= .NetCore 2.0"

Tutorial:

1. Install package: Install-Package NDT.Elasticsearch.Log4net.Appender -Version 1.0.0
2. Config:

1. NetFramework:

• In Web.config:

  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <appSettings>
    <add key="log4net.Internal.Debug" value="true" />
  </appSettings>
  <log4net>
    <appender name="elasticappender" type="demo_lib_log4net_appender.Appender.UsexpressAppender, demo_lib_log4net_appender">
          <elasticNode value="http://elastic:changeme@localhost:9200" />
          <enableGlobalContextLog value="false" />
          <disableLocationInfo value="false" />
          <disableConnectionPing value="false" />
          <indexPattern value="ddMMyyyy" />
          <baseIndex value="logentry" />
    </appender>
    <root>
          <level value="ALL" />
          <appender-ref ref="elasticappender" />
    </root>
  </log4net>
  

  • In AssemblyInfo.cs

     [assembly: log4net.Config.XmlConfigurator(Watch = true)]
    

2. NetCore:

• Create log4net.config:

   <log4net>
      <appender name="elasticappender" type="demo_lib_log4net_appender.Appender.UsexpressAppender, demo_lib_log4net_appender">
          <elasticNode value="http://elastic:changeme@localhost:9200"></elasticNode>
          <enableGlobalContextLog value="true"></enableGlobalContextLog>
          <disableLocationInfo value="false"></disableLocationInfo>
          <disableConnectionPing value="false"></disableConnectionPing>
          <indexPattern value="yyyy-MM-dd"></indexPattern>
          <baseIndex value="demo_elastic_log4net_"></baseIndex>
      </appender>
  
      <root>
        <level value="ALL" />
        <appender-ref ref="elasticappender" />
      </root>
   </log4net>
  

• In Startup.cs, add this code in contructor:

    XmlConfigurator.Configure(LogManager.GetRepository(Assembly.GetEntryAssembly()), new FileInfo("log4net.config"));
  

3. Note:

• http://elastic:changeme@localhost:9200 : elastic is default username, changeme is default password

• <baseIndex value="demo_elastic_log4net_"></baseIndex> : demo_elastic_log4net_ is my index

3. Using:

• Logging.log.Info("Your message hear");
• Logging.log.Info(JsonConvert.SerializeObject(object)); //Install Newtonsoft.Json to use it
