Jonathan Hurley updated AMBARI-7955:
------------------------------------
Description:
Adds "host-only" alerts to the alert framework infrastructure. Alerts that are
only for a host are those that are run on every host in the cluster and are not
bound to any particular stack service. They exist "outside" of the stack.
In order to accomplish this, several changes were made:
1) A new alerts.json was created at the root resources directory to represent
host-only alerts. This file is parsed separately from the stack but its
definitions are merged into the database in the same manner as those from the
stack
2) These new alerts must be bound to the service AMBARI and component
AMBARI_AGENT
3) Host alerts are usually custom scripts; a new directory was needed so that
resources could be copied from the Ambari Server to the Agent in the same
manner that the stack and custom_actions resources are copied. This is the new
"host_scripts" directory.
4) RPM updates to ensure that "host_scripts" is properly packaged.
was:
Expose the ability through the REST API and on the stack to define alerts that
are independent of any Hadoop services and run on every host in the cluster.
These should be associated with the AMBARI_AGENT "service" that is currently
exposed for treating agents as their own distinctive service.
