Prometheus libvirt exporter

Project forked from https://github.com/kumina/libvirt_exporter and substantially rewritten. Implemented support for several additional metrics, ceph rbd (and network block devices), ovs. Implemented statistics collection using GetAllDomainStats

This repository provides code for a Prometheus metrics exporter for libvirt. This exporter connects to any libvirt daemon and exports per-domain metrics related to CPU, memory, disk and network usage. By default, this exporter listens on TCP port 9177.

This exporter makes use of libvirt-go, the official Go bindings for libvirt. This exporter make use of the GetAllDomainStats()

The following metrics/labels are being exported:

libvirt_domain_info_maximum_memory_bytes{domain="..."}
libvirt_domain_info_memory_usage_bytes{domain="..."}

Repository contains a shell script, build_static.sh, that builds a statically linked copy of this exporter in an Alpine Linux based container.
