Are you referring to the APM Server config file or one of the agents?

Not in the config file, as it will be read and parsed as a string.  
For that you will need to set this configuration via environment variable or system property.

Hi @Eyal_Koren! Thanks for the answer. So I can set some of my settings in the config file and some others via environment variable or system property?

Then I will set only this one via env and hope it works 😃

Thx
