Config
======

Schema file: ``docs/config.schema.json``

Log path rule
-------------

Logs are stored under:

::

   <logPath>/<configName>/YYYY/MM/<source>/log_YYYYMMDD.json

``configName`` defaults to the config filename (without extension).
A copy of the config is stored as ``config.json`` under that folder when
server mode starts. If the same name exists but content differs, the
existing folder is backed up before a new one is created.

Linux package defaults:

- ``fileLog.logPath`` = ``/var/lib/gop/``
- ``api.logPath`` = ``/var/log/gop/api.log``
