A prometheus-libvirt-exporter for host and vm metrics exposed for prometheus, written in Go with pluggable metric collectors. By default, this exporter listens on TCP port 9177, path '/metrics', to expose metrics.
This exporter is built upon the go-libvirt package developed by DigitalOcean. It offers a pure Go interface for interacting with Libvirt, leveraging the RPC interface provided by Libvirt. For detailed information about the Go bindings used, you can refer to the Libvirt API reference.
This release provides a set of assets for the prometheus-libvirt-exporter. It includes installation packages for various platforms (apk, deb, rpm) and the the binaries. Additionally, source code archives in both zip and tar.gz formats are available for download.
