# Configure the logging system

Tiledesk uses [Winston](https://github.com/winstonjs/winston) as logging library. The Tiledesk server is configured with the following transports :

* the console
* logs files under /logs/app.log folder

## Configure the log level

The default log level is INFO. If you want to change the log level use the `LOG_LEVEL` environment property as follow:

```
LOG_LEVEL="verbose"
```

## Enable logs to MongoDB

Optionally you can write the logs to the MongoDB database (adding a MongoDB transport to Winston) with the following environment property:

```
WRITE_LOG_TO_MONGODB="true"
```

You can also change (default value is INFO) the level for the MongoDB transport with the following property:

```
LOG_MONGODB_LEVEL="error"
```
