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=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}
curl
http://localhost:8983/solr/admin/autoscaling?diagnostics=true&wt=json&indent=on
{code}
or API v2:
{code}
http://localhost:8983/v2/cluster/autoscaling?diagnostics=true&wt=json&indent=on
{code}

was:
Expose a diagnostics API to gives details of how loaded each node is, according
to the configured cluster policy and preferences. This should probably fold
into the autoscaling read APIs added in SOLR-10373.
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}
curl
http://localhost:8983/solr/admin/autoscaling?diagnostics=true&wt=json&indent=on
{code}
or API v2:
{code}
http://localhost:8983/v2/cluster/autoscaling?diagnostics=true&wt=json&indent=on
