The CLT 'showruntimestats' has been extended with paramer '-e' ('--eventstats'). Using it leads to the following output:

org.apache.felix.eventadmin.monitoring:type=EventA dminMBean,EventsPerMinute = <integer>
org.apache.felix.eventadmin.monitoring:type=EventA dminMBean,EnqueuedEvents = <integer>
org.apache.felix.eventadmin.monitoring:type=EventA dminMBean,TotalEventCount = <integer>

This output is also included when using the '--allstats' option.

Meaning of the result values:
EventsPerMinute: A moving average of delivered events per minute.
EnqueuedEvents: Numberof events that are temporarily cached and wait for delivery.
TotalEventCount: Number of events that have been delivered since the application was started.
