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
Then forked again from https://github.com/rumanzo/libvirt_exporter_improved and rewritten. Implemented meta metrics and more info about disks, interfaces and domain.
And then forked again from https://github.com/AlexZzz/libvirt-exporter and rewritten to use the go-libvirt library instead of native C libvirt bindings. Changed error handling and some metrics to suit my current needs. Also fixes the memory metrics to use data provided by the balloon driver, which when coupled with memory autodeflation gives accurate memory usage data.
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.
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_binary.sh, that builds the binary in a golang docker image, since compiling in alpine images results in a corrupted binary.
