Deployment

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

Functional tests

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.

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
