Don't count messages on arbitrary keys
That is, don't use a key constructed from an incoming Diameter header unless the message is known to the dictionary in question. Otherwise there are 2^32 application ids, 2^24 command codes, and 2 R-bits for an ill-willed peer to choose from, each resulting in new keys in the counter table (diameter_stats). The usual {ApplicationId, CommandCode, Rbit} in a key is replaced by the atom 'unknown' if the message in question is unknown to the decoding dictionary. Counters for messages sent and received by a relay are (still) not implemented.
