In addition, for every table there is a gauge with the number of items of said table.
Metric name is rethinkdb_table_items_total{db="...",table="..."}
There are also total counters for numer of servers, tables and replicas as well as number of
errors returned from the stats table.
Metric names are rethinkdb_cluster_[servers|server_errors|tables|replicas]_total
