You can't capture a trace on a router without turning on debug, which could have a severe effect on performance, and also won't catch packets that are fast switched. Routers don't really make very good troubleshooting tools. Are these packets that you are denying with an access list? If yes, you can add the log keyword to the access list. Then you can see some info about the packets that were filtered by the list on the console, or wherever you send your logging messages. In general, what you want to do is better handled by an Intrustion Detection System (IDS), than a router. A router forwards (or blocks) packets. It should be optimized to do this. It doesn't make a good troubleshooting or logging tool. It's not supposed to.
