> The Cloud->Nodes view lists all nodes, grouped by host. However, if a node is 
> temporarily down (not in live_nodes), the whole screen is broken, and instead 
> error messages like
> {noformat}
> Requested node example.com:8983_solr is not part of cluster{noformat}
> This happens on the Ajax request to fetch {{admin/metrics}} and 
> {{admin/info/system}}. A better approach would be to skip requesting metrics 
> for downed nodes but still display them in the list, perhaps with a DOWN 
> label or other background colour, to clearly tell that the node is configured 
> but not live.
