Hello Jim,
What do you say,
One event type with parameters:
- method name
- method parameters
OR
Lots of event types with parameters:
- method parameters
Lots of event types that subclass a single event type.
That want if you want them all, you subscribe to the base type,
otherwise, subscribe to the ones you want. Note that you don't need
to define interfaces for these, as subscribers can just subscribe to
classes.

It might also be nice to have this generate events. That is, the
tracing storage should call zope.event.notify.
I intent in 3.8 or 3.9 to start having ZODB depend on zope.event. We
really should have used events rather than adding the callback's
we've added recently.

Hello Christian,
Gosh, that looks simple. A simple decorator pattern on the storage.
So I shall create a branch, something like
svn://svn.zope.org/repos/main/ZODB/branches/tracing-storage
from
svn://svn.zope.org/repos/main/ZODB/trunk
and start there?

Hi,
I'm pretty sure there are no hooks around that do what you need.
The methods you want to tap into would be
store()
load*()
on the storages.
You might want to look into how the BlobStorage was created to make
yourself a "tracing storage" that can be wrapped around an existing
storage to allow usage with multiple other storages.
This could be a useful extensions to ZODB. If you go this way,
I'd be
happy to help out with some of the packaging mechanics and getting
the
ZConfig parts fletched out.

Hello,
I'm using ZODB in a GUI application, so outside of Zope.
I'm having performance problems. I'm already on the way of
figuring
out what causes a lot of object load. getTransferCounts helped in
that. But now I would need something more detailed.
Are there any hooks or something to get detailed object load
statistics?
Worst case I could hook into some methods of ZODB temporarly to
collect the data, but into which methods?
Any help or pointers are welcome.
