What are the best or most useful configurations for logging with NLog? (These can be simple or complex, as long as they're useful.)
I'm thinking of examples like automatically rolling over log files at a certain size, changing the layout (log message) whether or not there is an exception, escalating the log level once an error has occurred, etc.
Here are some links:
Easier Way To Log each log level with a different layout using Conditional Layouts
<variable name="VerboseLayout" value="${level:uppercase=true}: ${longdate} | ${logger} :
${when:when=level == LogLevel.Trace:inner=MONITOR_TRACE ${message}}
${when:when=level == LogLevel.Debug:inner=MONITOR_DEBUG ${message}}
${when:when=level == LogLevel.Info:inner=MONITOR_INFO ${message}}
${when:when=level == LogLevel.Warn:inner=MONITOR_WARN ${message}}
${when:when=level == LogLevel.Error:inner=MONITOR_ERROR ${message}}
${when:when=level == LogLevel.Fatal:inner=MONITOR_CRITICAL ${message}} |
${exception:format=tostring} | ${newline} ${newline}" />
