Logs not write to Elastic in aspnet.core

[chenzhe014]

i want to add fileds in my logs from elasticsearch .

var myLogger = LogManager.GetCurrentClassLogger();
var eventInfo = new LogEventInfo(NLog.LogLevel.Info, myLogger.Name, sb.ToString());
eventInfo.Properties["Tag"] = dic["tag"];
myLogger.Log(eventInfo);

But it will only be recorded in local files,and will not be recorded in elasticsearch. when i append logger.LogInformation("n")(Microsoft.Extensions.Logging) . it will be recorded in elasticsearch. I have tried this many times and this is always the result.

Log Code:

var myLogger = LogManager.GetCurrentClassLogger();
var eventInfo = new LogEventInfo(NLog.LogLevel.Info, myLogger.Name, sb.ToString());
eventInfo.Properties["Tag"] = dic["tag"];
myLogger.Log(eventInfo);
//logger.LogInformation("n");

Nlog.Config

Instead of jumping into the deep end of the pool, then try something simple.

Forexample this setting will carry a lot of suprises:

<default-wrapper xsi:type="BufferingWrapper" bufferSize="5"/>

Instead try this NLog.config instead:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="Warn"
      internalLogFile="internal-nlog.txt">

  <extensions>
    <add assembly="NLog.Web.AspNetCore"/>
    <add assembly="NLog.Targets.ElasticSearch"/>
  </extensions>

  <!-- define various log targets -->
  <variable name="logDirectory" value="${basedir}/logs/${shortdate}"/>

  <targets async="true">
    <target xsi:type="File"
            name="allfile"
            fileName="${logDirectory}/nlog-all/${shortdate}.log"
            keepFileOpen="true"
            concurrentWrites="false"
            />

    <target xsi:type="File"
            name="ownLog-file"
            fileName="${logDirectory}/nlog-${level}/${shortdate}.log"
            keepFileOpen="true"
            concurrentWrites="false"
            />

    <target xsi:type="ElasticSearch" name="elastic" layout="${logger} | ${threadid} | ${message}" index="qunar_api" includeAllProperties="true" requireAuth="true" username="****" password="******" uri="http://localhost:9210" />
  </targets>

  <rules>
    <logger name="*" minlevel="Trace" writeTo="allfile" />
    <logger name="Microsoft.*" maxlevel="Info" final="true" />
    <logger name="*" minlevel="Info" writeTo="elastic" />
  </rules>
</nlog>
