Description

Hi all,

I was trying to find a way to monitor the real storage write latency observed by ActiveMq and I could not find.

The only thing that I found was a log line:

https://github.com/apache/activemq/blob/master/activemq-kahadb-store/src/main/java/org/apache/activemq/store/kahadb/MessageDatabase.java#L1142

 

I think would be really useful to have this information on the PersistenceAdapterViewMBean.

 

The change proposed create a new attribute on this bean called "Statistics" - that contains write and read times statistics - and a operation to reset it.

 

OBS: This information can be extended to all other persistence adapters.

 

Thanks
