PowerFlow output to Syslog repository

We're looking at enabling Syslog output to a central repository from PowerFlow at an application level. We've already got this running fine at an OS level and SL1 at an application level.

Has anybody setup logging for PowerFlow? We're specifically interested in any login type data and also code changes. I've been through as much doc as I can find on the topic, such as:

https://docs.sciencelogic.com/pdf/sciencelogic_powerflow_2-1-1.pdf

https://docs.docker.com/engine/logging/drivers/syslog/

https://support.sciencelogic.com/s/article/10819

It doesn't appear straight forward to link log files in /var/log/iservices to their respective Docker services.

I'm just looking for validation as much as anything, that Docker level logging of the contentapi and gui processes would be the way forward to capture all relevant security related information, and that all other processes can be ignored.
