Question

Is it possible to change the source name thru code? My solution has several modules and I want to separate them when viewing the logs.

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <targets>
    <target xsi:type="EventLog" name="eventlog" layout="${message}" log="Application" source="MyAwesomeSolution"/>
  </targets>
  <rules>
    <logger name="*" minlevel="Info" writeTo="eventLog" />
  </rules>
</nlog>

Also, how do I log objects as xml? e.g. if I do this – logger.Info("Results - {0}", person); I want to view the person object as XML in my event log. Is it possible?

Answer 1

Initalize your Logger object with

private static Logger logger = LogManager.GetCurrentClassLogger();

then you can add

${callsite} to your layout in config file

e.g.

<targets>
    <target xsi:type="EventLog" name="eventlog" layout="${callsite}:${message}" log="Application" source="MyAwesomeSolution"/>
</targets>

More info @ ${callsite} is here.
