Question

I run into the same issue described there:
Another StackOverflow Question

I need to log to file and method calling.
The problem is that there are lot of “debug” level logging messages which are more detailled.
I need them to log to file. But the method should only receive logging messages above debug level.

So the SplitGroupTarget doesn’t fullfill my requirements.
Is there any solutions or workarounds for this problem?

Additionally i found this entry in the NLog forum with a similiar problem in 2006 – but with no answer yet: NLog Forum

EDIT1: I forgot to mention that i want to configure this programmatically.
According to your answer i tried it in the following way, but only the last target gets logged.

SimpleConfigurator.ConfigureForTargetLogging(methodCallTarget, LogLevel.Debug);
SimpleConfigurator.ConfigureForTargetLogging(fileTarget, LogLevel.Debug);

Answer 1

I just found the solution to log multiple targets programmatically.

I just don’t use the SimpleConfigurator but the LogManager to set the NLog.LoggingConfiguration to its property.

So i came out with following code snippet:

// define the targets
// ......

// create configuration object and set previously created targets
LoggingConfiguration configuration = new LoggingConfiguration();
configuration.AddTarget("methodCall", methodCallTarget);
configuration.AddTarget("logfile", fileTarget);

// create logging rules where i can specify the minimum log levels
// and add them to the configuration objects LoggingRules Enumerable.
LoggingRule logFileRule = new LoggingRule("*", NLog.LogLevel.Debug, fileTarget);
configuration.LoggingRules.Add(logFileRule);

LoggingRule methodCallRule = new LoggingRule("*", NLog.LogLevel.Info, methodCallTarget);
configuration.LoggingRules.Add(methodCallRule);

// Finally set the configuration object to the LogManagers Configuration property
LogManager.Configuration = configuration;

Thanks for your answers!
