Hi Adrian:
Shouldn't this be discussed on the "user" list? IMHO Words like
"applications" and "stats about services and entities"...those are all
indicative of user requirements, not developer requirements.
Users should be driving requirements gathering and analysis for OFBiz
and not developers.
Just my 2 cents.
Regards,
Ruth

At first glance, this might seem like a duplication of

the base component, and it is designed to be used to measure any

I know that there are features in the ServerHitBin class to gather
stats about services and entities, but I don't remember how they are
implemented and if they are fully used.

The ServerHitBin entity and service methods are not used currently.
Metrics could be kept for entities, but I don't think that they would
be meaningful - so I didn't add them. If someone comes up with a need
for entity metrics, then the capability can be added easily.
In a nutshell, the ServerHitBin code is quite heavy - it uses the
entity engine to store the metrics. The design I used is from SEDA -
it is meant to be used in a "feedback loop" that is used to control
web application response times, so it is small and fast. Also,
ServerHitBin stats are kept for every request, but the metrics code is
more strategic - you maintain metrics only in the areas you are
concerned with.
