Hi @TB3dock ,
As per the documentation AEM as a Cloud Services does not support custom log files, however it does support custom logging.
For Java logs to be available in AEM as a Cloud Service (via Cloud Manager or Adobe I/O CLI), custom log statements must be written the error.log. Logs written to custom named logs, such as example.log, will not be accessible from AEM as a Cloud Service.
So in this case I would recommend to have have custom logging message as per your project so that you can grep or search for it.
