----------------------------------

             Summary: 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: 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...
