# Logger

Type: `logger`

This handler simply writes to your tenant log file. It jots down the fact that a given event fired. This can be useful while debugging or while designing your workflow models.

Here is an example that registers the handler for the `START` event of a workflow:

```
{
    "handlers": {
        "START": [{
            "type": "logger",
            "config": {}
        }]
    }
}
```
