Downtime Pie Chart Panel

Libre Panel for Pie Chart Downtime Analysis

This chart visualizes the part-to-whole of downtime categories and reasons. The outer donut is the part-to-whole of the selected inner category. Users can select an inner category to change the outer donut display. Users can toggle between downtime category/reason duration sum and frequency of occurrences. A download button enables saving the graph as an image. Mouseover gives users additional information as to the downtime duration. This panel plugin is part of Libre.

This panel has been developed for Grafana v6.x.x only.
