How to set logs to ELK in kibana with authentication using serilog

Step1: Install this NuGet package "Serilog.Sinks.Elasticsearch"

Step2: Add this in App.config or Web.config

<appSettings>    <add key="elasticsearchURL" value="your_URL" />    <add key="elasticsearchuserName" value="your_Username" />    <add key="elasticsearchpassword" value="your_Password" />    <add key="elasticsearchIndex" value="indexname-{0:yyyy.MM.dd}" /> <!-- make sure index start with small letter --></appSettings>

Step3: Add this in program.cs in main() OR Global.asax in Application_Start()

Log.Logger = new LoggerConfiguration()        .MinimumLevel.Debug()        .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(ConfigurationManager.AppSettings["elasticsearchURL"]))        {            AutoRegisterTemplate = true,            ModifyConnectionSettings = x => x.BasicAuthentication(ConfigurationManager.AppSettings["elasticsearchuserName"], ConfigurationManager.AppSettings["elasticsearchpassword"]),            IndexFormat = ConfigurationManager.AppSettings["elasticsearchIndex"]        })        .CreateLogger();

Step4: Log events where you want by adding

 using Serilog; Log.Error("Your_Message", ex); Log.CloseAndFlush();

If you want to use with log4net then

Step1: Install this NuGet package "log4net.Elasticsearch"

Step2: Add this "[assembly: log4net.Config.XmlConfigurator(Watch = true)]" in AssemblyInfo.cs

Step3: Add these things in web.config

<configSections>   <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /></configSections><runtime>   <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">       <dependentAssembly>           <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />           <bindingRedirect oldVersion="0.0.0.0-2.0.8.0" newVersion="2.5.0" />       </dependentAssembly>   </assemblyBinding></runtime><log4net>   <appender name="ElasticSearchAppender" type="log4net.ElasticSearch.ElasticSearchAppender, log4net.ElasticSearch">       <connectionString value="Scheme=http;Server=your_IP;Index=index_name;Port=9200;User=your_Username;Pwd=your_Password;rolling=true;" />  <!-- make sure index start with small letter -->   </appender>   <root>       <level value="ALL" />       <appender-ref ref="ElasticSearchAppender" />   </root></log4net>

Step4: Log events where you want by adding

using log4net;private static readonly ILog _log = LogManager.GetLogger(typeof(your_mainpageclass));_log.Error("your message ", ex);_log.Logger.Repository.Shutdown();
