Mr. Høydahl,
I like the idea of using color on shards, may "blue" for inactive and the
default (empty circle) for the active shards but we can leave the replicas as
it is. I completely understand that would be somehow not suited to the eyes,
less human-readable but for an inactive shard, there will be a leader and the
nodes will have their own state (active,down,recovering) which will not be
serving requests.
Let me know your thoughts, along with feedback from others, I would like to
write the patch for this after we decide on what we need.

> Admin UI -> Cloud -> Graph: Impossible to see shard state

> Key: SOLR-10147
> URL: https://issues.apache.org/jira/browse/SOLR-10147
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Admin UI
> Reporter: Jan Høydahl
>
> Currently in the Cloud -> Graph view there is a legend with color codes, but
> that is for replicas only.
> We need a way to quickly see the state of the shard, in particular if it is
> active or inactive. For testing, create a collection, then call SPLITSHARD on
> shard1, and you'll end up with shards {{shard1}}, {{shard1_0}} and
> {{shard1_1}}. It is not possible to see which one is active or inactive.
> Also, the replicas belonging to the inactive shard are still marked with
> green "Active", while in reality they are "Inactive".
> The simplest would be to add a new state "Inactive" with color e.g. blue,
> which would be used on both shard and replica level. But since an inactive
> replica could also be "Gone" or "Down", there should be some way to indicate
> both at the same time...
