-----------------------------------
Summary: AlertReceivedListener produces large number of db requests
Key: AMBARI-11528
URL: https://issues.apache.org/jira/browse/AMBARI-11528
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.
