#### network-bandwidth
You can configure which network interface you want to view the bandwidth,
Displaying of the interface name, The interval between each bandwidth update.
The most common interfaces name are `eth0` for a wired connection and `wlan0` for a wireless connection.
```bash
set -g @dracula-network-bandwidth eth0
set -g @dracula-network-bandwidth-interval 0
set -g @dracula-network-bandwidth-show-interface true
```
#### network-ping options
You can configure which server (hostname, IP) you want to ping and at which rate (in seconds). Default is google.com at every 5 seconds.
