-----------------------------------
Summary: Handle scenario when host in-memory aggregation is not
working
Key: AMBARI-21279
URL: https://issues.apache.org/jira/browse/AMBARI-21279
Project: Ambari
Issue Type: Task
Components: ambari-metrics
Affects Versions: 3.0.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Fix For: 3.0.0
If monitor aggregation is enabled we do not do collector side 5 minutes
aggregation. If a monitor is down we do not get metrics from that host. Metrics
collector should check that metrics from a host are available per minute but
aggregates are not.
This could be based on liveliness check of a monitor. More like a heartbeat
ping. When we loose ping for > 1 min < 5 min we can aggregate metrics for that
time period and hostId.
Sinks and monitor should switch back to collector reporting state if local
aggregation app is not available.
