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:
By default 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
```
By default 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:
