This charm provides the Prometheus libvirt exporter (via the snap).
A typical deployment with nova and libvirt is as follows:
(The metrics will be at http://nova-compute:9177)
juju deploy nova-compute
juju deploy prometheus-libvirt-exporter
juju add-relation nova-compute prometheus-libvirt-exporter
To avail of the metrics in grafana the following steps can be used:
juju deploy grafana
juju deploy prometheus2
juju add-relation prometheus-libvirt-exporter:scrape prometheus2:target
juju add-relation prometheus-libvirt-exporter:dashboards grafana:dashboards
To setup reporting with nagios:
juju deploy nrpe
juju add-relation nova-compute nrpe
juju add-relation prometheus-libvirt-exporter:nrpe-external-master nrpe:nrpe-external-master
To change or update dashboards:
# The exporter is distributed with a standard dashboard
# To provide your own dashboards, create a zip file and attach it as a resource
zip grafana-dashboards.zip libvirt-simple.json libvirtadvanced.json
juju attach-resource prometheus-libvirt-exporter dashboards=./grafana-dashboards.zip
This directory needs to be create in the charm path prior to testing
mkdir -p report/lint
Juju should be installed and bootstrapped on the system to run functional tests.
export HTTPS_PROXY=http://<your_proxy
export NO_PROXY=127.0.0.1,localhost,<juju_controller_ips>
export MODEL_SETTINGS=<semicolon-separated list of "juju model-config" settings>
make test
NOTE: If you are behind a proxy, be sure to export a MODEL_SETTINGS variable as described above. Note that you will need to use the juju-http-proxy, juju-https-proxy, juju-no-proxy and similar settings. Also you will need to export HTTPS_PROXY used in the test and export NO_PROXY that should include ips of controller subnet and model subnet.
