-----------------------------------------

             Summary: Alerts UI: Alerts Instances keep storing in DS.Store even after user
navigate away
                 Key: AMBARI-8399
                 URL: https://issues.apache.org/jira/browse/AMBARI-8399
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.0.0
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
             Fix For: 2.0.0


There may be huge number of the alert instances. 
In big cluster this may cause performance issues.
Example: 
cluster with 200 nodes.
every node has 10-20 alert instances.

user navigates to {{host1/alerts}}. 20 alerts are saved to DS.Store. 20 overall
user navigates to {{host2/alerts}}. 15 alerts are saved to DS.Store. 35 overall
.....
In some moment may be situation when 2000-4000 alerts will be stored on the UI.

*Expected behavior:*
cleanup alert instances models when new list of models is loaded.
