Monasca Datasource - A datasource for use with the OpenStack Monasca api.
For more information on Monasca see the Monasca documentation
The Monasca Horizon plugin offers Horizon integration for Monasca. Among other things this plugin proxies the Monasca metrics API, using the Horizon session for authentication (as opposed to a Keystone token). This proxied API can be used to let this plugin access the Monasca API with the privileges of the user logged in to Horizon.
Note that this is entirely separate from Grafana’s user management.
Setting this up requires the following steps:
Install and configure the
monasca-uiHorizon plugin. Specifically you will need to set
GRAFANA_LINKSto your dashboards which can either be JSON dashboards you point to or in-database dashboards. In the former case set the links’
pathattribute to the dashboard’s path or full URL. In the latter case, set the links’
False(or omit it entirely) and set their
pathattributes to the database dashboards’ names.

Configure the VHost hosting your Horizon instance with a proxy path that points at your Grafana instance (the example assumes you are running Horizon on Apache - adapt as required for other web servers):
ProxyPass "/grafana" "http://my.grafana.server:3000" ProxyPassReverse "/grafana" "http://my.grafana.server:3000"

[server] root_url = %(protocol)s://%(domain)s/grafana
Configure the plugin as follows:
- Http settings:
http://my.dashboard.server/monitoring/proxy(substitute your dashboard’s actual host name for
- Access: direct

Steps (2) and (3) are neccessary to ensure both Grafana and Horizon are
on the same Host/Port from the browser’s perspective. Otherwise the
browser’s XSS protection mechanisms will omit the Horizon session cookie
from any requests triggered by the
When combined with Grafana Keystone authentication this datasource supports using login credentials to authenticate queries.
Without the Grafana Keystone auth, this datasource can be used by
inserting a keystone token into the datasource. To get a keystone token
download the python-openstackclient, source credentials and run
openstack token issue.
