* 'b' switch between bit/s or byte/s for network IO
* 'c' sort the processes list by CPU consumption
* 'd' disable or enable the disk IO stats
* 'e' enable the sensors module (PySensors lib is needed)
* 'f' disable or enable the file system stats
* 'l' disable or enable the logs
* 'm' sort the processes list by process MEM

For example, on a 100 Mbps Ethernet interface, the warning status is set
if the bit rate is higher than 70 Mbps.
### Sensors (optional)
![screenshot](https://github.com/nicolargo/glances/raw/master/doc/sensors.png)
Optinaly, Glances displays the sensors informations (lm-sensors).
You should enable this module using the following command line:
glances -e
There is no alert on this information.

### Capteur (en option)
![screenshot](https://github.com/nicolargo/glances/raw/master/doc/sensors.png)
Glances peut afficher les informations sur les capteurs (lm-sensors).
Ce module est optionnel et doit être activé avec l'option:
