hello Michal, That was my worries as well, and I think that your advice is probably the right one. Or even, I'm might request an enhancement to the collect libvirt plugin to report also FS information. What I'd like to see is libvirt's ability to spawn commands inside guest. But it is not that simple. I mean, the hardest part is to design

For instance, we'd have to deal with both blocking & non-blocking (i.e. long-running) commands; then we would need to give users possibility to read command's output (possibly asynchronously). With this, you'd just: virDomainRunCommand(dom, 'df', '-h', NULL); or something and you'd be good.
Not as straightforward as you'd like, but if you use QEMU you can already achieve something similar via qemu-guest-agent. https://www.redhat.com/archives/libvir-list/2016-August/msg00339.html -- Andrea Bolognani / Red Hat / Virtualization
