[Lxc-users] LXC Statistics Collection

[Francois-Xavier Bourlet]

Hi,

In fact I am writing a lib to abstract the collections statistics
about LXC containers that live on the host, outside containers. I
already have a plugin for collectd using this lib. An alpha version
will be released soon, just need to fix some details about
architectures and licenses.

Thanks for your advice, the first version will walk directly in
/var/lib/lxc and use the abstract socket open by LXC to check if a
containers is running. I actually have the cpu and memory accounting
and planing to add the networking part soon.

I will keep you tuned when I have public repositories.
