I’m using the Nlog, and for each client logged into the system I would like to create a log generation behavior as follows:
[nome-cliente-1]-[dataAtual].txt
[nome-cliente-2]-[dataAtual].txt
Ex: Joao-da-silva-01-11-2016.txt
I would like the information to be written in the generated file only on the day. If I arrived at midnight I would create another file, so that there is one file per day for each client.
I searched for tutorials but found nothing like.

Raphael,
Follow as I did with the NLOG, install the Packages via nuget:
Install-Package NLog
Install-Package NLog.Config
In Nlog.config include to targets the section below:
<target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}-${environment:variable=CLIENT_NAME}.log"
layout="${longdate} ${uppercase:${level}} ${message}" />
To log the error the way you want: client and current date in the file in filename, just follow the default for what you need.
NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();
try
{
Environment.SetEnvironmentVariable("CLIENT_NAME", "Cliente 001");
throw new Exception("Cliente 001 error");
}
catch (Exception e)
{
logger.Error(e.Message);
}
The date that the variable {shortdate} creates in this format "2016-11-03", if necessary, create another environment variable for your context.
Thank you very much, Rodrigo! I did it this way but it did not generate the folder with the file, you have idea of what can be?
Raphael, according to the filename, will be created a folder called logs within the application executable location, (in our scenario will be created within the Bin folder) with the file named 2016-11-03-Client 001.txt. Sure that no log file has been generated?
Yes, no file :( Strange because I made the settings without any problem. I’ll give a check.
Raphael, follow the repository to test: https://github.com/rodrigoacr/NLogExample
Ah, I thought! The "writeTo" was not pointing to the target name. Thank you very much Rodrigo! Thanks!

In the file Nlog.Config I set the file name this way
fileName="/erros/${date:format=yyyy\MM}//${date:format=dd} - ${event-properties:item=name}.json">
and to log in do as follows:
Logger log = LogManager.GetCurrentClassLogger();
LogEventInfo theEvent = new LogEventInfo(LogLevel.Fatal, "", e.Message);
theEvent.Properties["name"] = "Nome";
log.Log(theEvent);
