Nlog not loggin to File

my nlog not creating files. I Use the same configuration in another project and everythink is Ok, but in new project nlog not create new files.
Nlog config :
<?xml version="1.0" encoding="utf-8" ?>
autoReload= "true"
internalLogLevel =" Trace"
internalLogFile ="c:\temp\internal-nlog.txt">
<targets>
<target name="file" xsi:type="File"
layout="${longdate} ${logger} ${message}${exception:format=ToString}"
fileName="C:\beka\logs\logfile.txt"
/>
<target name="exceptions" xsi:type="File"
layout="${longdate} ${logger} ${message}${exception:format=ToString}"
fileName="C:\beka\logs\logfileExceptions.txt"
/>
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="file" />
<logger name="*" minlevel="Error" writeTo="exceptions" />
</rules>
On the console I can see that the log has been called but its not sent to a file.
I think the problem can be in c:\temp\internal-nlog.txt becouse this file has references to another project. And when i start another project internal-nlog.txt is update but when i start this project internal-nlog-txt doesnt update
Nlog action = content,
Copy to outputDirectory = copy if newer

GraylogHttp dosen't expand formatted string from Common Logging

I have a Graylog logging server set up for all our projects. One of the projects is using NLog and it uses a framework with Common Logging.
When the framework logs, the messsage received in Graylog is {0}. So somewhere it's string formatting not done.
If i configure a parameter and send in $(message) there, the expanded message is sent.
Also, the colored console configured works as expected.
<?xml version="1.0" encoding="utf-8" ?>

</target>
</targets>
<rules>
<logger name="*" minlevel="Trace" appendTo="graylog"/>

</rules>
</nlog>
The code used for calling looks like this (Relevant parts...)
using Common.Logging;
internal static ILog Logger = LogManager.GetLogger<SboApp>();
Logger.Error($"UI Connect Error: {ex.Message}", ex);
I'm using
Common.Logging.NLog4412 v 3.4.1
NLog v 4.4.12
NLog.Targets.GraylogHttp v 0.0.24
What am i doing wrong

NLog weirdness - extra fields displayed

I use NLog for debugging/tracing in my app. What's happening is that I am seeing some extra stuff in the output. This is C#/VisualStudio on the Mac, targeting iOS.
Here is an example...
I'm using a target of type "Debugger", and my layout line is:
<layout="${time} ${level} ${callsite}:${callsite-linenumber} ${message}"/>
The call to the logger is:
log.Debug("Added New Key. Code = {0}", code);
And the output is:
AppleLibrary.PasswordMgr: 16:04:36.4064 Debug
AppleLibrary.PasswordMgr.SavePassword:55 Added New Key. Code = -34018
Every debug line starts with <logger name>:
Its even worse when I use a target type of "Console" with exactly the same layout. A call like this:
log.Debug("Started Application");
ends up with this:
2017-06-14 16:04:23.673 MyApp.iOS[11942:6245589] 16:04:23.6374 Debug MyApp.iOS.Application.Main:14 Started Application
in this case every line starts with: 2017-06-14 16:04:23.673 MyApp.iOS[11942:6245589], which looks like the long date, logger name and thread/tick information.
Note that this does not happen with my file target, even though it uses exactly the same layout! The above call shows this in the logfile.txt:
16:04:23.6374 Debug MyApp.iOS.Application.Main:14 Started Application
Which is exactly what I want.
Here is my NLog.config:
<?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" throwExceptions="true">
<targets>
<target name="logfile"
xsi:type="File"
header="############STARTING RUN ${date} ${time}"
archiveOldFileOnStartup="true"
maxArchiveFiles="5"
fileName="/Users/Paul/Dev/MyApp/MyApp.iOS/logfile.txt"
layout="${time} ${level} ${callsite}:${callsite-linenumber} ${message}"/>
<target name="console" xsi:type="Console"
layout="${time} ${level} ${callsite}:${callsite-linenumber} ${message}"/>
<target name="debugger"
xsi:type="Debugger"
layout="${time} ${level} ${callsite}:${callsite-linenumber} ${message}"/>
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="logfile" />
<logger name="CoreLibrary.*" minlevel="Trace" writeTo="debugger" enabled="false" />
<logger name="AppleLibrary.*" minlevel="Debug" writeTo="debugger" />
<logger name="MyApp.iOS.*" minlevel="Debug" writeTo="console" />
</rules>
</nlog>
I'd appreciate any pointers as to what I'm misunderstanding here.
Thanks.
Paul.

NLog in .NET 4.5 console app: not loading Configuration

I have some console apps I've written at work. I'd like to get NLog into them but I am having trouble.
When I inspect the 'logger' object, I see in it's 'Factory' property, that the configuration had targets=0, loggingrules=0, everything blank or unset.
So, it doesn't do ANYTHING.. doesn't drop an internal log file either... I have tried nLog.config NLog.config and nlog.config... to no avail. Tried ver 3 and 4 of NLog too...
Why would it not pick up the config?
I have:
NLog.config in the root with 'Content' for build action and 'Copy Always' set
Confirmed the NLog.config IS being copied to the bin
Here's the NLog.config:
<?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"
throwConfigExceptions="true"
throwExceptions="true"
internalLogLevel="Trace"
internalLogFile="c:\temp\NlogInternal.log"
internalLogToConsole="true"
internalLogToConsoleError="true"
internalLogToTrace="true">
<targets>
<target xsi:type="Console" name="debugConsole" layout="${message} "/>
<target xsi:type="File" name="debugFile" createDirs="true" fileName="c:\temp\testlog.log" layout="${longdate} ${uppercase:${level}} ${message}"/>
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="debugConsole"/>
<logger name="*" minlevel="Trace" writeTo="debugFile"/>
</rules>
</nlog>
and finally (this doesn't error, but nothing is output since the config is blank):
private static Logger logger = LogManager.GetCurrentClassLogger();
logger.Info("ConsoleApp test log...");

Do your app.config have a NLog configSection?
Something like this:
<configuration>
<configSections>
<section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog"/>
</configSections>
<nlog>
</nlog>
</configuration>

If even the internalLogger isn't working, you could debug the issue by setting
the InternalLogger.LogWriter
e.g.
// enable internal logging to a custom TextWriter
InternalLogger.LogWriter = new StringWriter(); //e.g. TextWriter writer = File.CreateText("C:\\perl.txt")

I got the same issue on my end. When you make change your fileName Path "c:\temp\testlog.log" to
"c:/temp/testlog.log" then it will work. Hope the below snipet help you to resolve the issue.
<targets>
<target xsi:type="Console" name="debugConsole" layout="${message} "/>
<target xsi:type="File" name="debugFile" createDirs="true"
fileName="c:/temp/testlog.log" layout="${longdate} ${uppercase:${level}}
${message}"/>
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="debugConsole"/>
<logger name="*" minlevel="Trace" writeTo="debugFile"/>
</rules>

Params in LogEntries configuration

Using the default configuration for LogEntries, is it possible to create insert parameterized values into the layout?
<nlog>
<extensions>
<add assembly="LogentriesNLog" />
</extensions>
<targets>
<target name="logentries" type="Logentries" debug="true" httpPut="false" ssl="false" layout="${date:format=ddd MMM dd} ${time:format=HH:mm:ss} ${date:format=zzz yyyy} ${logger} {SOME PARAM FROM CONFIG} : ${LEVEL}, ${message}">
</target>
</targets>
<rules>
<logger name="*" minLevel="Trace" appendTo="logentries" />
</rules>
</nlog>

I'm an idiot sometimes.
You can just stick them in the layout string
<target name="logentries" type="Logentries" debug="true" httpPut="false" ssl="false" layout="${date:format=ddd MMM dd} ${time:format=HH:mm:ss} ${date:format=zzz yyyy} : ${LEVEL}, ${message}, ${SomeParam}"></target>
