### Options description

| Name | Value | Description |
| ------------------------------------------- | ---------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **apiOutputType** | String among {`off`, `table`, `json`} | Configure the default output type of coincenter (can be overridden by command line)queries |
| **fiatConversion.rate** | Duration string (ex: `8h`) | Minimum time between two consecutive requests of the same fiat conversion |
| **log.activityTracking.commandTypes** | Array of strings (ex: `["Buy", "Sell"]`) | Array of command types whose output will be stored to activity history files. |
| **log.activityTracking.dateFileNameFormat** | String (ex: `%Y-%m` for month split) | Defines the date string format suffix used by activity history files. The string should be compatible with [std::strftime](https://en.cppreference.com/w/cpp/chrono/c/strftime). Old data will never be clean-up by `coincenter` (as it may contain important data). User should manage the clean-up / storage. |
| **log.consoleLevel** | String | Defines the log level for standard output. Can be {'off', 'critical', 'error', 'warning', 'info', 'debug', 'trace'} |
| **log.fileLevel** | String | Defines the log level in files. Can be {'off', 'critical', 'error', 'warning', 'info', 'debug', 'trace'} |
| **log.maxFileSize** | String (ex: `5Mi` for 5 Megabytes) | Defines in bytes the maximum logging file size. A string representation of an integral, possibly with one suffix ending such as k, M, G, T (1k multipliers) or Ki, Mi, Gi, Ti (1024 multipliers) are supported. |
| **log.maxNbFiles** | Integer | Number of maximum rotating files for log in files |
