README

        # Prometheus libvirt exporter

Docker image is available at [dockerhub](https://hub.docker.com/r/alekseizakharov/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.

## Libvirt/qemu version notice

Some of the above might be exposed only with:

`libvirt >= v7.2.0`:

libvirt_domain_vcpu_delay_seconds_total

# 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](https://libvirt.org/). 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](https://gitlab.com/libvirt/libvirt-go-module), the official Go

bindings for libvirt. This exporter make use of the

`GetAllDomainStats()`
