Use glances network alias if available

[LeviSnoot]

Is your feature request related to a problem? Please describe. I have a dual boot machine with Arch and Windows 11. I figured I'd set up glances on Windows since both installs use the same IP, it'd basically be portable. The only issue is, the network interface name on Arch is enp7s0 and Ethernet on Windows. As I'd like to keep both names to their defaults, I added the following to my glances.conf on Windows:

[network]
Ethernet_alias=enp7s0

Now the Ethernet adapter appears as enp7s0 in the web interface, and if we look at http://localhost:61208/api/3/network, an alias value has been added:

 {
    "interface_name": "Ethernet",
    "alias": "enp7s0",
    "time_since_update": 8.07380199432373,
    "cumulative_rx": 52488594,
    "rx": 41836,
    "cumulative_tx": 6760822,
    "tx": 22377,
    "cumulative_cx": 59249416,
    "cx": 64213,
    "is_up": true,
    "speed": 1048576000,
    "key": "interface_name"
  }

I presume Homepage fetches the network interface using the value of interface_name, regardless if it has an alias, so it still fails to grab the network interface.

Describe the solution you'd like If the value of alias is null, use interface_name. If the value of alias is anything else, use alias for the network interface name.

Describe alternatives you've considered

• Renaming either network interface on my system: I'd like to keep both interface names to their defaults to prevent any potential configuration issues on either system.

Hi @LeviSnoot

in Glances version 4 (future version under development), the default behavor for the aliases will be the following.

[network]
alias=enp7s0:Ethernet

Result in the API:

{
    "interface_name": "enp7s0",
    "alias": "Ethernet",
    "time_since_update": 8.07380199432373,
    "cumulative_rx": 52488594,
    "rx": 41836,
    "cumulative_tx": 6760822,
    "tx": 22377,
    "cumulative_cx": 59249416,
    "cx": 64213,
    "is_up": true,
    "speed": 1048576000,
    "key": "interface_name"
  }
