Hmm. You could replace do a s/method/_method/ kind of thing on the read methods and have method in ObjectStore ping the trace point and then call _method. The writes are slightly trickier/simpler. I suggest you add ObjectStore level _start_transaction(uint64_t seq, Transaction*) and _end_transaction(uint64_t seq, Transaction*) methods to allow the implementation to tag the beginning and end of a transaction. You can then iterate through the transaction and emit appropriate events perhaps? -Sam
