> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Dmytro Sen
> Assignee: Dmytro Sen
> Priority: Critical
> Fix For: 2.1.0

>
> In 5-min snapshot processing of onAlertEvent method took ~94 seconds
> producing 46k commits and almost same amount of db requests (~equally split
> between alert_history and alert_definition tables)
> this can be related to large amount to alerts, but it should be addressed as
> we can have even more alerts on larger clusters, and it can be caused by a
> single thread only for all listeners, so there's possible bottleneck here.
