Using pyshark to measure net usage to suspend a server.
Example:
Tue Apr 5 18:57:04 2022 source: x.x.x.x:5353 IP to: x.x.x.x UDP size: 110
Tue Apr 5 18:57:04 2022 source: x.x.x.x:50589 IP to: x.x.x.x TCP size: 74
Tue Apr 5 18:57:04 2022 source: x.x.x.x:52143 IP to: x.x.x.x TCP size: 74
Tue Apr 5 18:57:04 2022 source: x.x.x.x:46731 IP to: x.x.x.x TCP size: 74
Tue Apr 5 18:57:04 2022 source: x.x.x.x:45697 IP to: x.x.x.x TCP size: 74
Tue Apr 5 18:57:04 2022 source: x.x.x.x:33103 IP to: x.x.x.x TCP size: 74
eno1 is idle. Average packet size is: 349.9259259259259.
There are no known services running. We can suspend now.

If there are any services that currently run on the server you can specify the IP to have the script re-run the packet capture 3 times to make sure the network is not in use.
