Review request for Ambari, Aravindan Vijayan and Sid Wagle.
Bugs: AMBARI-21279
https://issues.apache.org/jira/browse/AMBARI-21279
Repository: ambari
Description
-------
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.
