Enable event logs.

Define logger for storing logs. It supports "filesystem", "database" and "flexiapi".

Directory where event logs are written as a filesystem (case when filesystem output is chosen).

Type of backend that Soci will use for the connection.
Depending on your Soci package and the modules you installed, the supported databases are:`mysql`, `sqlite3` and `postgresql`

Configuration parameters of the backend.
The basic format is "key=value key2=value2". For a mysql backend, this is a valid config: "db=mydb user=user password='pass' host=myhost.com".
Please refer to the Soci documentation of your backend, for instance: http://soci.sourceforge.net/doc/master/backends/#supported-backends-and-features

Amount of queries that will be allowed to be queued before bailing password requests.
This value should be chosen accordingly with 'database-nb-threads-max', so that you have a coherent behavior.
This limit is here mainly as a safeguard against out-of-control growth of the queue in the event of a flood or big delays in the database backend.

Maximum number of threads for writing in database.
If you get a `database is locked` error with sqlite3, you must set this variable to 1.

Domain name or IP address of the FlexiAPI host. This setting will be used in combination with flexiapi-port and -prefix to contact the API located at <flexiapi-host>:<flexiapi-port><flexiapi-prefix>

Port on the FlexiAPI host. See `flexiapi-host` for details.

Path prefix for FlexiAPI requests. See `flexiapi-host` for details.

API authentication key for the FlexiAPI
