The logger component lets you define the level of logging activities in Home Assistant.

To enable the logger in your installation, add the following to your `configuration.yaml` file:

To have a full log and log everything only this entry is needed (without any qualifier):
```yaml
logger:
```
To log all messages and ignore events lower than critical for specified components.

```yaml
# Example configuration.yaml entry
logger:
  default: info
  logs:
    homeassistant.components.device_tracker: critical
    homeassistant.components.camera: critical
```

To ignore all messages lower than critical and log event for specified components.

```yaml
# Example configuration.yaml entry
logger:
  default: critical
  logs:
    homeassistant.components: info
    homeassistant.components.rfxtrx: debug
    homeassistant.components.device_tracker: critical
    homeassistant.components.camera: critical
```

Possible log severities are:
