> SolrCloud doesn't provide any aggregate stats about the cluster or a
> collection. Very common questions such as document counts per shard, index
> sizes, request rates etc cannot be answered easily without figuring out the
> cluster state, invoking multiple core admin APIs and aggregating them
> manually.
> I propose that we expose an API which returns each of the following on a
> per-collection and per-shard basis:
> # Document counts
> # Index size on disk
> # Query request rate
> # Indexing request rate
> # Real time get request rate
> I am not yet sure if this should be a distributed search component or a
> collection API.
