Subject [jira] [Commented] (AMBARI-5445) When new host components are created thru API, some indication should be given that Nagios has to be restarted
Date Fri, 11 Apr 2014 17:32:16 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-5445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13966842#comment-13966842

Sumit Mohanty commented on AMBARI-5445:
---------------------------------------

With some input from [~mahadev] how about a more generic solution:
* Introduce the concept of a "monitoring" service
** Nagios and Ganglia are two such services
* A monitoring service, by definition, needs to be restarted when host components are added/removed
** Restart is indicated by setting a flag (if we can user stale_config = true that will be
great) on all service host components
* The indicator itself is reset when a host component starts

[~dsen], can you check if the above steps fit and provide a detailed proposal
