Shalin Shekhar Mangar updated SOLR-10677:
-----------------------------------------
Description:
Expose a diagnostics API to gives details of how loaded each node is, according
to the configured cluster policy and preferences as well as a list of
violations for rules given in the policies.
By adding {{/diagnostics}} to the {{/admin/autoscaling}} path (for v1 API) or
{{/cluster/autoscaling}} path (for v2 API), the API returns the list of nodes
in sorted order according to the cluster preferences configured.
API v1:
{code}
curl http://localhost:8983/solr/admin/autoscaling/diagnostics
{code}
or API v2:
{code}
http://localhost:8983/v2/cluster/autoscaling/diagnostics
{code}

was:
Expose a diagnostics API to gives details of how loaded each node is, according
to the configured cluster policy and preferences as well as a list of
violations for rules given in the policies.
By adding {{diagnostics=true}} as a request parameter for /admin/autoscaling
(for v1 API) or /cluster/autoscaling (for v2 API), the API returns the list of
nodes in sorted order according to the cluster preferences configured.
API v1:
{code}
