You can check the NP drop counters using the "show drops" command on ASR. You can get basically the same data by doing "show controller np ports all location <location>" to find the relevant NP then do "show controllers np counters <np> <location>". There's usually a lot of data there and it can be hard to wade through, but that's the best place to start, IMO.
