Stefan Matheis (steffkes) commented on SOLR-4770:
-------------------------------------------------
Actually .. what we might do w/o a change to the zookeeper-data is *drum roll*
using state-of-the-art JSONP. which allows the UI to fetch information from
remote hosts.
Of course that would mean, that if we'd like to show some kind of
cluster-overview presented as a table (all nodes visible at once) .. it might
take a while, to generate that one, because we have to issue N HTTP-Requests to
display it.
On the other hand, displaying this information (only) on-demand might work out
w/o problems, since it's only one node at a time.
While writing about the Idea of a cluster-overview (as table) which i find
pretty nice, not sure if it's that helpful? It reminds me a bit about Foreman
(http://theforeman.org/static/images/screenshots/host_listing.png) ... :)
> Mouse-over info for other nodes in SolrCloud rendering

>
> Key: SOLR-4770
> URL: https://issues.apache.org/jira/browse/SOLR-4770
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.2
> Reporter: Mark Bennett
>
> We render a nice graphical view of your current cluster from the URL
> http://localhost:8983/solr/#/~cloud
> It'd be nice to gather some info about those other nodes without having to
> visit them. Since you can't right-click to open those nodes in another tab,
> your only choice now is to duplicate that tab, and then click the link.
> This was mentioned in SOLR-4438 but Stefan Matheis (steffkes) requested that
> it be broken out into a separate task and detailed a bit more.
> Mouse-Over often indicates a Balloon-help style thing, but another option is
> to reserve another part of the screen down below that can display node info,
> and then refresh it as the mouse hovers over various nodes. I'm not sure
> which is easier nor which is more accessible.
> Sadly some devices don't support Hover, and the click method is already used
> to take you to that other node. So perhaps it'd be easier to display some
> type of "(i)" / Info icon that you can specifically click on to see that
> node's info, without jumping to it.
> Specific items it might be nice to see:
> (generally mirroring what's on default Dashboard screen if you were to visit
> that node)
> * Start
> * Host
> * CWD
> * Instance
> * Data
> * Index
> * Solr & Lucene version (to help with upgrading, though not sure we need all
> 4 fields?)
> Resources:
> * JVM meory
> * maybe Physical Memory
> * Some hint about disk stats?
> Args of:
> -DnumShards
> -DzkRun
> -STOP
> ... not sure how many.... could get too much, but some would be handy
