> Add REST API to Storm UI
> ------------------------
>
> Key: STORM-205
> URL: https://issues.apache.org/jira/browse/STORM-205
> Project: Apache Storm (Incubating)
> Issue Type: New Feature
> Reporter: P. Taylor Goetz
>
> It would be helpful to have a RESTful API to expose the metrics currently
> available in Storm UI.
> This would allow integration with 3rd-party monitoring and visualization
> services.
> The REST services could either be implemented within the Storm UI service, or
> as a separate Storm daemon.
