Looks like the Settings, Indexes page has the statistics for the local file system(s) where indexed data is stored on that node. Since my index master is not an indexer, all the statistics are zero meaning there is no local bucket storage on that node. The Settings, Index Clustering, Indexes is the cluster wide metrics for all indexers cumulatively. I discovered this by browsing to all the indexers Settings, Indexes and found the metrics were different per node. All together they added up to Settings, Index Clustering, Indexes.
So, the Settings, Indexes is local. Settings, Index Clustering, Indexes is the sum of all index cluster members.
