> If a node is {{{}/live_nodes{}}}, but a replica hosted on that node is
> {{DOWN}} ( or missing from the Metrics API response section for that node for
> any other reason) this breaks a brittle assumption in the {{cloud.js}} logic
> that generates the data structure used to power the
> {{/solr/#/~cloud?view=nodes}}
> The current assumption is that _any_ replica found in the {{CLUSTERSTATUS}}
> response, hosted on a live_node, will be found in the Metrics API response --
> when this is not true, the javascript throws a {{TypeError}} while looping
> over the metrics API response, leaving the datastructure it was building
> incomplete.
> This means that, depending on _where_ in the (effectively) random order that
> the metrics API returns node details, all or some of the nodes visible on the
> resulting admin UI screen will be missing data from the metrics API (most
> notably in the Disk Usage column) depending on whether they came "after" the
> node hosting the problematic replica.
> There is nothing obvious in the UI to indicate that a particular node/replica
> is having a problem -- making it particularly hard to identify why columns
> like Disk Usage are "blank"
