             Summary: Alerts: Nagios Target for Notifications
                 Key: AMBARI-8165
                 URL: https://issues.apache.org/jira/browse/AMBARI-8165
             Project: Ambari
          Issue Type: Task
          Components: contrib
    Affects Versions: 2.0.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
             Fix For: 2.0.0


The Ambari Server will be responsible for scheduling the dispatching of alerts 
that have been received and not yet processed for outbound notification. On a 
schedule, Ambari will determine the alert targets that should be receiving some 
sort of notification and then it will gather all alert data for all alerts that 
are destined for that alert target.

Nagios is a required notification mechanism. The Nagios server will surface the 
current state of each alert defined in the system. In order to accomplish this 
there are two possible methods for implementation:

1) Write a python script that Nagios will execute on its own schedule which can 
then retrieve the current alerts from Ambari's REST APIs. The script will take 
a combination of parameters (host, security, certificate, etc) in order to make 
the requests.

2) Write a dispatcher that can handle pushing data to a Nagios server. There 
will no longer be an agent running on Nagios, so this method would need to work 
with Nagios' built-in mechanism, if any, for publishing data into Nagios.
