For logging in GLASS, we've got the Object Log, which is basically an
OrderedCollection of ObjectLogEntries (name, priority, timestamp, object
reference) that is kept in memory...The advantage is that you can
inspect the items directly rather than print the information that you
think you need.
For GemStone, the size of the collection doesn't matter so I log all
kinds of things like mfc events, gems starting up and shutting down ...
the collection is shared across all vms, so you only have to look in one
place no matter how many server gems you have running ...
There's also a Seaside component for accessing the Object Log.
Other than having to manage the size of the collection, I think an
object log is superior to the print-based form almost every time:)
