I am trying to get the user identity from ASP.NET to log using NLog but it is not working. Nothing is logged for {aspnet-user-identity} or {aspnet-request-ip}. I have the layout renders in my nlog.config file, but the resulting log messages do not show values for the aspnet layout renderers. It’s not logging this information in the file or the database.

Below is my nlog.config file:

<?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="Info"
    internalLogFile="C:/Temp/Logs/internal-nlog-AspNetCore.txt">
    <extensions>
        <add assembly="NLog.Web.AspNetCore" />
    </extensions>
    <targets>
        <!-- File target -->
        <target
            xsi:type="File"
            name="file"
            fileName="C:/Temp/Logs/Template/Template_${shortdate}.log"
            layout="${longdate}|${aspnet-request-ip}|${aspnet-user-identity}|${level:uppercase=true}|${logger}|${message}|${exception:format=tostring}" />
        <!-- Database target -->
        <target
            xsi:type="Database"
            name="database"
            connectionString="${configsetting:item=ConnectionStrings.DefaultConnectionString}"
            dbProvider="System.Data.SqlClient.SqlConnection,System.Data.SqlClient"
            commandText="INSERT INTO Log (Logged, Level, Message, Logger, Exception, UserIdentity, RequestIP) VALUES (@logged, @level, @message, @logger, @exception, @useridentity, @requestip)">
            <!-- Define database logging parameters -->
            <parameter name="@logged" layout="${longdate}" dbType="DateTime" />
            <parameter name="@level" layout="${level}" />
            <parameter name="@message" layout="${message}" />
            <parameter name="@logger" layout="${logger}" />
            <parameter name="@exception" layout="${exception:format=tostring}" />
            <parameter name="@useridentity" layout="${aspnet-user-identity}" />
            <parameter name="@requestip" layout="${aspnet-request-ip}" />
        </target>
    </targets>
    <rules>
        <logger name="*" minlevel="Info" writeTo="file" />
        <logger name="*" minlevel="Info" writeTo="database" />
    </rules>
</nlog>

Here is the log file and you can see the aspnet-request-ip and aspnet-user-identity are empty strings:
