Question: Application Insights - Write to "exceptions" and not "traces"

[hiraldesai]

What do I need to do to write the unhandled exceptions to "exceptions" tab in Application Insights instead of the usual "Traces" tab?

This is what my setup is:

            var config = new LoggingConfiguration();
            var target = new ApplicationInsightsTarget
            {
                InstrumentationKey = _instrumentationKey
            };

            var rule = new LoggingRule("*", LogLevel.Trace, target);
            config.LoggingRules.Add(rule);

            LogManager.Configuration = config;

And this is how I'm logging:

private readonly ILogger<ClassName> _logger;
public ClassName(ILoggerFactory loggerFactory) 
{
_logger = loggerFactory.CreateLogger<CustomErrorHandlingMiddleware>();
}
...
...
_logger.LogError(0, exception, exception.Message);
...

Everything is ending up under "traces" tab, nothing under "exceptions" tab.

I get you are using NLog target? It suppose to track exception as long as LogEventInfo item has it not empty. See here.

Do you know if ILogger -> NLog initializes this field properly? I do not have experience with this combination of loggers.

Thank you for the reference @SergeyKanzhelev. Yes, I'm using NLog target, I will look into more details to figure out if it's populating it correctly.
