             Summary: Review the naming conventions used by JMXReporter to register the Metric MBeans
                 Key: SLING-5443
                 URL: https://issues.apache.org/jira/browse/SLING-5443
             Project: Sling
          Issue Type: Improvement
          Components: Commons
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra
             Fix For: Commons Metrics 1.0.2


With current setup the JMXReporter would register all metrics under {{org.apache.sling}} domain. [~pfaffm@adobe.com] suggested that this can cause confusion as metrics registered by non Sling bundle would also show up in Sling JMX domain. 

We should customize the JMX ObjectName logic to account for bundle which has registered the metrics. One approach that can be used is 

# Expose the MetricService as a ServiceFactory
# Have an OSGi config which provides a mapping between Bundle-SymbolicName and JMX Domain name to use. It would be a regex expression. The metric though MUST be unique across all metrics (irrespective of which bundle was used)
{noformat}
com.foo = com.foo.*
org.apache.sling=org.apache.sling.*
