Prometheus libvirt exporter

• Dockerfile - creates a docker container with dynamically linked libvirt-exporter. Make an image and run with docker container run -p9177:9177 -v /var/run/libvirt:/var/run/libvirt yourcontainername. Based on the latest golang:alpine.
• build-with - builds dynamically linked libvirt-exporter in the container based on Dockerfile specified as an argument. Ex.: build-with ./build_container/Dockerfile.ubuntu2004 will build libvirt-exporter for Ubuntu 20.04.

Historical

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()
