Move KairosDB out of grafana to a external plugin repo

[torkelo]

As of Grafana 3.0 (master) KairosDB data source will no longer be included in official builds. But work has been done to make it easier to install plugins.

Clone into plugins directory

Either clone this repo into your grafana plugins directory (default /var/lib/grafana/plugins if your installing grafana with package).
Restart grafana-server and the plugin should be automatically detected and used.

git clone git@github.com:grafana/datasource-plugin-kairosdb.git
sudo service grafana-server restart

Clone into a directory of your choice

The edit your grafana.ini config file (Default location is at /etc/grafana/grafana.ini) and add this:

[plugin.kairosdb]
path = /home/your/clone/dir/datasource-plugin-kairosdb

Note that if you clone it into the grafana plugins directory you do not need to add the above config option. That is only
if you want to place the plugin in a directory outside the standard plugins directory. Be aware that grafana-server
needs read access to the directory.
