------------------------------
    Component/s: storm-core

> Support status messages on Storm UI
> -----------------------------------
>
>                 Key: STORM-59
>                 URL: https://issues.apache.org/jira/browse/STORM-59
>             Project: Apache Storm
>          Issue Type: New Feature
>          Components: storm-core
>            Reporter: James Xu
>
> https://github.com/nathanmarz/storm/issues/342
> Set the status message as a string through the config.
> Status message should display by itself if Nimbus is down, otherwise display on the top of the cluster UI
> -----------------------------
> jasonjckn: One common issue is zookeeper goes down, it'd be nice if the status message reported ZK online/offline.
> Also, the most common instant message I get are "when will it be up?" and "if I'm working on the problem" can the status message be dynamically set?
> -----------------------------
> nathanmarz: We can just update the config file and have the UI reload the config each time it receives a request.
> -----------------------------
> jasonjckn: In the situation where ZK is offline. I don't want to have to manually set the status message about ZK online/offline. I want to be the consumer of this information. It'd be great, if the error page was server rendered, and we did a quick ZK connect, to see if it exists. The code could be easily added to src/clj/backtype/storm/ui/core.clj
> We could still have a status message in the config, which would be read by error page in ui/core.clj.
> -----------------------------
> nathanmarz: Good idea. This would be in addition to a status message. We can call this "health checks."
