[jira] [Comment Edited] (SOLR-5749) Implement an Overseer status
API
[ https://issues.apache.org/jira/browse/SOLR-5749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13950348#comment-13950348 ]

Thanks for reviewing Otis.
bq. Could this be exposed via JMX, like the rest of the stats?
It'd probably be hard for someone to monitor it with jmx because the mbeans will be published only on the overseer node (which can change from time to time).
The naming is actually copied over from the RequestHandlerBase.getStatistics, except that we track requests per minute instead of per second. I thought we could keep them same in both places for consistency. Would you still prefer to change?

> 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
