xenstats_exporter's Issues

Please export additional VM metrics

Hi,

it would be much appreciated if the xenstat_exporter could export additional VM metrics such as, but not limited to, VM_metrics.get_VCPUs_utilisation, VM_metrics.get_VCPUs_CPU, VM_metrics.get_memory_actual, ... as this would allow for monitoring of running guests as well.

Thank you!

[Question]: is it possible to put the image in DockerHub?

So I don't need build image locally?
