The dashboard displays the essentials metrics you need to know that your cluster is healthy. The dashboard also provides an overview of your nodes and indices, displayed in two clean tables along with the relevant key metrics. These tables serve as an entry point to more details on the Node Statistics and Index Statistics dashboards, where you can see more than 90 different metrics plotted over time. Simply click on a table cell or select multiple nodes/indices to compare and you’ll be transferred to the relevant place in the detailed dashboard.
