How to check Blocked traffic on a Cisco router?
We recently switched a bunch of ACL's to a Cisco 1921 and are trying to check to see the blocked traffic coming into or out of the router. Is there any easy way of doing this similar to other firewalls like an ASA or sonicwall? For the life of me I can't seem to figure it out 
I've tried some debugging rules but it doesn't seem to show what I need.
thanks!

You need to include the word "log" at the end of your ACL that's denying traffic -

And then pump all the stuff to a syslog like kiwi? That the easiest tool? -

You can do that or you can also look at the internal buffer, but be mindful of CPU utilization.
