tracker-server.log not found

Folks,
For some reason, I can't find any log files at opt/traccar/logs in my ubuntu machine in Digital Ocean.

Any ideas why and how to enable?

Thank you

Is the server running? Have you changed any configuration?

The server is running. I installed using the process outlined here on traccar.org for Digital Ocean installation.

Everything seems to be working fine. I was looking for the logs so I can identify the port for a new device we're integrating

Is the logs setting true in the traccar.xml

Thanks Anders,
I do not have this setting in the traccar.xml file. But it is in the default.xml as follows:

    <entry key='logger.enable'>true</entry>
    <entry key='logger.level'>info</entry>
    <entry key='logger.file'>./logs/tracker-server.log</entry>
    <entry key='logger.rotate'>true</entry>

Is there a need to repeat in the traccar.xml?

Hi Anders and Anton,
I implemented above settings in traccar.xml and now I have the server logs ! Yay!

I'd thought you only needed to include in traccar.xml settings in default.xml that you wanted to override.

Many thanks!
