> Now summary information on Router website aggregates summary of each nameservice. However
in a typical federation cluster deployment, datanodes are shared among nameservices. Consider
we have 2 namespaces and 100 datanodes in one cluster. 100 datanodes are available for each
namespace, but we see 200 datanodes on the router website. So does other information such
as {{Total capacity}}, {{Remaining capacity}}.
