Summary

Grafana panel for displaying metric sensitive or arbitary HTML.

This only works with Grafana 3.X or later

The control allows the specification of CSS, HTML and JS for both initialisation and metric updates.

This is based on the work by Marcus Calidus and the SVG plugin.

Installation

It is possible to clone this repo directly into your plugins directory. (var/lib/grafana/plugins)

Afterwards restart grafana-server and the plugin should be automatically detected and used.

npm install
grunt
sudo service grafana-server restart

Clone into a directory of your choice

If the plugin is cloned to a directory that is not the default plugins directory then you need to edit your grafana.ini config file (Default location is at /etc/grafana/grafana.ini) and add this:

[plugin.svg]
path = /home/your/clone/dir/svg-panel

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.

Options

HTML Data and CSS

HTML & CSS is encapsulated in a shadow root and will therefore not "leak" outside the control.
