NLog using When Condition Renderer for value availability
I have a value for log input (event-properties:item=Id
) but that value could be empty sometimes. I'd like NLog to generate a value (guid
) if it's null/empty. I'm trying this When Condition Renderer but I haven't been able to make it generate anything, the input value is still empty. What am I doing wrong?
<parameter name="Id" type="System.Guid"
layout="${when:when=length('${event-properties:item=Id}')>0:${event-properties:item=Id}:${guid:format=N}}"/>
Using NLog 4.5.
c# .net nlog

Alternative solution:
<parameter name="Id" type="System.Guid" layout="${event-properties:Id:whenEmpty=${guid:format=N}}" />
Btw. you might consider using GeneratedFromLogEvent
for the ${guid}
if writing to several targets. https://github.com/NLog/NLog/wiki/Guid-layout-renderer
