Mark Miller commented on SOLR-3162:
-----------------------------------
Wishlist item:
The zookeeper info has information about the current cluster state, but its not
really in a very user friendly consumable form.
It would be really great if we had a more graphical representation of cluster
using the information from zookeeper.
All of the information to build such a view is in the zookeeper servlet.
The clusterstate.json file has the layout and state about each node, and the
/live_nodes list gives which nodes are considered up and down by zookeeper.
Together, this gives the major status of the cluster.
So for a cluster that had a clusterstate.json with one collection, 2 shards,
and 2 nodes for each shard, you might imagine seeing 4 circles arranged in a
square under the heading "collection1". There would be a row of circles for
each shard and a column for each replica. One of the circles would represent a
shard entry that did not have a node_name under /live_nodes, so it would be
black. Another circle would represent a shard entry that had a node_name that
was under/live_nodes and had a state of active so it would be green. Another
circle would be good with /live_nodes but have a state of recoverying, so it
would be yellow. The final circle would be good with /live_nodes but have a
state of recovery_failed, so it would be red.
At a glance, you could roughly see what your cluster looked like, and what
state it was in. Then of course you could also add more, but this would be the
basics. Just an idea ;)
