> Ambari UI does not allow to modify threshold of *'OK'* and *'WARNING'* in ResourceManager WEB UI alert.
> *Steps to reproduce:*
> 1. Remove threshold from WARNING/OK at alert of ResourceManager WEB UI 
> 2. Save 
> 3. Refresh Ambari UI and and the field is blank *- Expected*
> 4. Add any threshold string (may be the one that you removed) to WARNING/OK and then save 
> 5. Refresh Ambari UI. _Here is the problem._ *It shows just blank.* 
> 6. API /api/v1/clusters/young-hdp250/alert_definitions/44 shows blank too. 
> - It's happening because the PUT call is sent empty.

> {code}
> "critical" : { 
>           "text" : "Connection failed to {1} ({3})" 
>         }, 
>         "ok" : { 
>           "text" : "HTTP {0} response in {2:.3f}s" 
>         }, 
>         "warning" : { 
>           "text" : "" 
>         } 
> {code}
> *Workaround:*
> Manual update using curl command works.
