A status dot panel for Grafana.
This panel shows a colored dot for each series. This is is useful if you want to monitor their status (i.e. latest value). Options for this panel include variable radius, precision and units (for the tooltip) and color thresholds for the value.
A separate tab allows you to customize how the display and color values are calculated for each dot, using mathjs.
The initial scope includes a data array, which is set to the compacted (no nulls) values of the series for each dot.
A further tab allows you to specify the hyperlink for each dot using variables derived from the name of its series.
The variables are set by splitting the series name on each . character and finding the value at the specified index.
This panel should work with the following data sources: Graphite
Docker is an easy way to spin-up an instance of Grafana. With docker installed, run the following command in the directory containing the plugin; this will expose the local plugin on your machine to the Grafana container so you can test it out.
docker run -it -v $PWD:/var/lib/grafana/plugins/status_dot -p 3000:3000 --name grafana.docker grafana/grafana
Now do this...
# Install development packages
npm install
# Install the grunt-cli
sudo npm install -g grunt-cli
# Compile into dist/
grunt
# Restart Grafana to see it
docker restart grafana.docker
# Watch for changes (requires refresh)
grunt watch
Use grunt test to run the Jasmine tests for the plugin; and grunt eslint to check for style issues. Note that the plugin controller isn't tested because it depends on Grafana native libraries, which aren't available outside of Grafana.
For bugs and new features, open an issue and we'll take a look. If you want to contribute to the plugin, you're welcome to submit a pull request - just make sure grunt runs without errors first.
