I'm trying to send my logs from java to splunk through log4j2 . I'm doing log4j2 configuration programatically.
I know this is not the correct way to do so. But I'm still doing this for learning purpose.
After execution of my java code I see the console appender logs in console but not the splunk appender logs in splunk. I don't know what I'm missing here.
I've tried with postman with same url and token. In this case it works well.
code of my POM file is here ==>
