Subject [jira] [Updated] (BROOKLYN-376) Make Brooklyn complain if ulimits etc. are not as required
Date Mon, 31 Oct 2016 12:55:58 GMT

     [ https://issues.apache.org/jira/browse/BROOKLYN-376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Geoff Macartney updated BROOKLYN-376:
-------------------------------------
    Description: 
The Brooklyn docs contain recommended settings for limits, entropy and other metrics it depends
on, but it would be even better if Brooklyn itself checked the values on startup and complained
loudly if they were not sufficient.  

At least a message in the logs would be valuable, or maybe even Brooklyn could refuse to start
without some flag acknowledging the user's acceptance of the low limits.

Additional possibilities would include:
* Expose the limits and whether they are sufficient through API
* Display this in the GUI
