Subject [jira] [Commented] (AMBARI-1409) Normalize all category/property/metric names available through the API
Date Tue, 12 Feb 2013 19:11:13 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13576901#comment-13576901
] 

Tom Beerbower commented on AMBARI-1409:
---------------------------------------

Right now the metric names already have a public name to internal name mapping in ganglia_properties.json
and jmx_properties.json.  We may be able to add an alias field to the mapping that would allow
us to keep the old public names for some period of time while we switch over to the normalized
public names.

> There is no standard for the property names available through the API. For the most part,
the public name of a metric is the same as the internal name from the back end (Ganglia, JMX,
Ambari DB). This includes a mix of upper case, lower case, camel case, underscore, dashes,
etc... We should define a standard for the public facing names that we expose through the
API. We need to come up with a mechanism that exposes the new public names but also makes
the existing names available for some time (unless we simply cut over to the new names for
the next API version).
