Installation
Plugin can be installed with git:
git clone git@github.com:flant/grafana-statusmap.git /var/lib/grafana/plugins/flant-statusmap-panel
Or you can download ZIP archive of this repo and unpack it into /var/lib/grafana/plugins directory.
Motivation
This plugin emerges from our needs to visually represent history of changes for a set of objects
with discrete statuses.
Objects can be hosts, Kubernetes pods or coffee makers and discrete statuses are a set
of predefined values: something like ok = 0, off = 1, fail = 2.
Configuration
Recommended setup is to create query for each possible status value with similar legend:
Next define color mapping for status values in Discrete color mode.
Spectrum and Opacity color modes works as in a Heatmap plugin.
More options
Multiple values check determine multiple values display mode. If check is unset then multiple values for one bucket treated as error. If check is on then color for bucket determined by value with least index in color mapping.
Null values can be treated as empty buckets or displayed as color of 0 value.
Min width and spacing are determine minimal bucket width and spacing between buckets. Rounding is for round edges.
Development
The easy way to test and develop plugin is to run Grafana instance in docker with following command in the directory containing the plugin. This will expose the local plugin on your machine to the Grafana container.
docker run --rm -it -v $PWD:/var/lib/grafana/plugins/flant-statusmap-panel \
-p 3000:3000 --name grafana.docker \
--env=GF_USERS_DEFAULT_THEME=light \
grafana/grafana:5.1.3
Now run grunt to compile dist directory and start changes watcher:
grunt watch
Acknowledgements
Idea of a plugin comes from Dmitry Stolyarov @distol, initial version written by Sergey Gnuskov @gsmetal and final changes made by Ivan Mikheykin @diafour.
This plugin is based on a "Heatmap" panel by Grafana and inspired by ideas from Carpet plot, Discrete panel, Status Panel, Status Dot, Status By Group.
