> Implement an Overseer status API
> --------------------------------
>
> Key: SOLR-5749
> URL: https://issues.apache.org/jira/browse/SOLR-5749
> Project: Solr
> Issue Type: Sub-task
> Components: SolrCloud
> Reporter: Shalin Shekhar Mangar
> Fix For: 5.0
>
> Attachments: SOLR-5749.patch, SOLR-5749.patch, SOLR-5749.patch
>
>
> Right now there is little to no information exposed about the overseer from
> SolrCloud.
> I propose that we have an API for overseer status which can return:
> # Past N commands executed (grouped by command type)
> # Status (queue-size, current overseer leader node)
> # Overseer log
