> 1. Stop a NodeManager. 
> *Actual result:*
> 2. Two alerts for the NodeManager appear quite soon on the corresponding Host Details
page and on the Hosts page. 
> 3. No alerts present on the ServicesPage->Yarn for at least 10 min. Same is true for
Dashboard->ClassicView->Yarn->NodeManagersLive. 
> 4. 1 alert appears some considerable time later. 
> *Expected result:*
> 3. Alerts and 'NodeManagers live' counter change synchronously with 2. 
> 4. *1* or *2* alerts should be present *?*
