Support for LXC/LXD containers

[crishoj]

Glances docs mention LXC in passing, but it appears that only docker and podman containers engines are implemented.

I propose adding glances/plugins/containers/engines/lxd.py with per-container stats (CPU, memory, disk IO, network) via the LXD API. Could use the official pylxd REST client.

Would you be interested in a PR for this feature?

Hi @crishoj !

It will be a nice feature for Linux users.

Feel free to propose a PR.

If you have any question, do not hesitate.

Nice! Here's a proposal: #3482

Please note that it uses polling, since LXD doesn't appear to have a streaming API.

Need some tests before closing.
