Summary

Grafana panel for displaying metric sensitive SVG images using the snap svg library (http://snapsvg.io/).

You need the latest grafana build for Grafana 3.0 to enable plugin support. You can get it here : http://grafana.org/download/builds.html

Example

Screenshot

Installation

It is possible to clone this repo directly into your plugins directory.

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

SVG Builder

Adding your own SVG repository

To add your own custom SVG graphics you have to fork the original project and add them to the assets folder. If your repository is of general concern and your license allows sharing you can also add it to the panel plugin via pull request on github

SVG Data

paste your svg code here. Don't forget to include a viewbox and IDs for all relevant objects.

Note: You cannot use SVG Data editor together with the use SVG Builder option checked!

onHandleMetric(ctrl: MetricsPanelCtrl, svgnode: HTMLElement)

svgnode passes the HTMLElement of the svg object on the panel. You can access the elements of the svg itself by using the integrated Snap Library. (http://snapsvg.io/)

var s = Snap(svgnode);
s.select('#status')
