NLog try another target when main target failed to log
Ok, I found out how to do it. The key is to use FallbackGroup as type of a target, and place the targets in correct order inside. Example: <target xsi:type="FallbackGroup" name="f" returnToFirstOnSuccess="true"> <target xsi:type="File" name="f" fileName="${basedir}/logs/${processname}-${shortdate}.log" layout="${longdate} ${uppercase:${level}} ${message}" /> <target xsi:type="EventLog" name="eventLog" layout="${longdate} ${uppercase:${level}} ${message}" source="MySource" log="Application" /> </target>...
.NET Object creation causing memory spike and doesn't go away
.net,performance,memory-management,memory-leaks,nlog
Do I need to add IDisposable to all these poco classes so they are removed right away? Anything that implements IDisposable should have IDisposable.Dispose() called as soon as the object is no longer needed. Typically the best way do accomplish that is with a using statement.

Wrapping Logging Frameworks
.net,logging,log4net,enterprise-library,nlog
By using a wrapper around your different logging frameworks you will only using the common functions of the logging frameworks. Each logging framework has its strong and weak points, in most cases you should choose the logging framework based on the requirements for logging and look at those points.
NUnit keeps running the wrong version of a .dll
c#,nunit,inversion-of-control,castle-windsor,nlog
Adding the following to the .nunit project file fixes this issue: configfile="Hl7ic.Engine.Test.dll.config" Even though the above runtime config setting was properly set in the test.dll.config, the nunit project didn't know to use the test.dll.config file. I always thought it was implicitly known to nunit, but apparently it needs to be...
Nlog Error(message, exception) ignore exception
exception,error-handling,.net-3.5,nlog
Nlog is using sepecial methods for logging exceptions which are using the <loglevel>Exception naming schema. So in your case you need to use the ErrorException method in order to your exceptions get logged correctly: private static Logger _logger = LogManager.GetCurrentClassLogger(); _logger.ErrorException("my message", new Exception("my exception")); ...
Nlog from an internal nuget library package
Most likely you made some error in your nlog.config but ... Please check if the NLog.dll versions you are using are the same (so, the version you build your MyLibrary.dll with and your WebFormsProject). Mind that as of NLog version 3.0, the support for dotnetfx20 has been dropped. dotnetfx35 is...
Is this the correct way to log to a specific target with NLog?
You always can create another logger instance where you want with specified name of target. What is the problem? For example I want to make an extended logging into a separate file. Than I go and create <rules> <logger name="ExtendedLogging" minlevel="Trace" writeTo="extendedLogging"/> </rules> <targets> <target name="extendedLogging" > <target xsi:type="File" fileName="C:/Logs/ExtendedLog${shortdate}.log"...
How to configure NLog (Servicestack) for Multiple files
You should be able to simply use ${threadid} (or if you name your threads, ${threadname}) in the filename layout.

How to mark exception as logged (and log it only once)?
c#,.net,exception-handling,nlog
Only catch it once. It doesn't matter how far up the call stack that is: the Stack Trace will be accurate. It's when you catch and rethrow and catch again that the Stack Trace gets changed. Catch it once, log it, handle it as you can and then don't throw...
What's the meaning of the time stamp in nlog when async is on?
c#,.net,timestamp,performance-testing,nlog
According to the NLog source: https://github.com/NLog/NLog/blob/master/src/NLog/Logger.cs the LogEventInfo objectc is created at the time of the logging call (and is timestamped at that point). The writing of the LogEventInfo object is then written, asynchronously, to the appropriate target(s). So, the timestamp in the logfile should represent the timestamp of...
NLog use in MVC applicaiton
Since you've already captured the error and you can't show the requested page, you could redirect within the catch to your error page: catch (Exception e) { logger.Error("Error in Index: " + e); return RedirectToAction("Index", "Error"); // Redirect to error controller or page } Alternatively, and probably more appropriate, you...

NLog Instance issue
When using the GetLogger method on NLog you get the instance you have configured in your configuration.

UIImageView image not returning nil but image not showing

Should I inherit the class logger when using NLog?
You should use a new one. LogManager.GetCurrentClassLogger creates a logger whose name is the current class. If you use the parent's class logger, you lose the information of the class doing the logging, it would appear as if the logging was done by the parent class. Most of the time,...

NLog and Common.Logging nightmare
Okay, so after all the fixes above I had to also update the Common.Logging package to v2.2.0.0 and then update the binding redirects manually. This is really a sub-optimal deployment of the Common.Logging.NLog20 nuget package. You shouldn't have to do this.

As it turned out, it was a bug (or a feature) in NLog. When writing to a 'target' in NLog asynchronously the original LogEventInfo that is written is added to the Parameters collection of a new LogEventInfo, thus the Properties collection where the {event-context} gets its values from is empty...
