-----------------------------------
Summary: Color Shard/Collection Graph Nodes Based on Child Node
Statuses
Key: SOLR-5047
URL: https://issues.apache.org/jira/browse/SOLR-5047
Project: Solr
Issue Type: Improvement
Components: web gui
Reporter: Thomas Murphy
Priority: Trivial
In the Solr Admin UI, only the leaf (individual core) nodes have colored
statuses, leaving collections and shards as no-context nodes. Having status
information for collections and shards would improve the ability for an
administrator to recognize which collections and shards are influenced by
server downtime on certain cores.
With increasing severity, the current core statuses are: Active, Recovering,
Down, Recovery Failed, Gone
The simplest plan:
* shards inherit the best status of their cores, one functioning core of that
shard implies that the shard is functional
* collections inherit the worst status of their shards, one missing shard
implies that the collection is not able to access data
More complicated, but accurate, would be appropriate indication of partially
failed shards and their influence on the total "health" of the collection.
