With the introduction of hidden indices, it looks like they are not included in the monitoring index_stats documents. (It's worth noting that the index total in cluster_stats monitoring documents is accurate (cluster_stats.indices.count)).
I'm also proposing we add additional mappings to indicate that the index is hidden, such as index_stats.hidden: <boolean>.
