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
And then forked again from https://github.com/rumanzo/libvirt_exporter_improved and rewritten. Implemented meta metrics and more info about disks, interfaces and domain.
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_block_meta{bus="...",cache="...",discard="...",disk_type="...",domain="...",driver_type="...",serial="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_allocation{domain="-...",target_device="..."}

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