> Key: UNOMI-465
> URL: https://issues.apache.org/jira/browse/UNOMI-465
> Project: Apache Unomi
> Issue Type: Bug
> Components: unomi(-core)
> Affects Versions: unomi-1.5.4
> Reporter: Risto Kowaczewski
> Priority: Critical
> Fix For: unomi-2.3.0
>
>
> I encountered the following error. When elasticsearch server has very little
> disk space it can go into read-only mode. Then it stops saving data. But
> there is no way the client (GUI, etc) knows that there is a problem.
> If you do not monitor elastic then you can go days without data being saved.
> I guess I will have to monitor elastic from GUI to alert users that something
> is not ok.
> This happens also when you create rule, segment, etc.
> Suggested approach is to use HTTP protocol as it is. And return data as it is
> but insted of 200 code return: 422 Unprocessable Entity.
> 422 Unprocessable Entity response status code indicates that the server
> understands the content type of the request entity, and the syntax of the
> request entity is correct, but it was unable to process the contained
> instructions.
> Using this approach will ensure that context server and the rest of unomi
> works but it indicates that there is something wrong.
