Review request for Ambari, Alejandro Fernandez, Nate Cole, and Tom Beerbower.
Bugs: AMBARI-10348
https://issues.apache.org/jira/browse/AMBARI-10348
Repository: ambari
Description
-------
Due to alerts being run on distributed platforms - we have problem wherein if
alert is scheduled to run on a host that goes down - its not obvious to
customer that alerts are not running and something is wrong. We need to do 2
things:
1. Generate an alert when not heard from Ambari Agent for quite sometime
2. Fire alerts which havent been run for quite sometime - saying they havent
been run due to host not responding.
Seems like 2 new alerts are required, both of which being "Server Side" (which
is a new concept).
- Ambari Server will need to maintain information about the last heartbeat from
a host and produce alerts when a heartbeat has not been received. A new
{{@AmbariService}} can handle this.
- Ambari Server will need to periodically check the last timestamp of all
enabled alert instances and determine if the alert has not run within a certain
period of time. A new {{@AmbariService}} can handle this.
We should utilize the alerts.json defined outside the stack since this affects
hosts and alert instants and is not bound to a cluster.
