Node & Index Statistics

The Node Statistics dashboard displays metric charts from the perspective of one or more nodes. Metrics include hardware level metrics (like load and CPU usage), process and JVM metrics (memory usage, GC), and node level Elasticsearch metrics such as field data usage, search requests rate and thread pool rejection.

The Index Statistics dashboard is very similar to the Node Statistics dashboard, but it shows you all the metrics from the perspective of one or more indices. The metrics are per index, with data aggregated from all of the nodes in the cluster. For example, the 'store size' chart shows the total size of the index data across the whole cluster.
