This counter tracks packets input to this module requiring RSA decryption, counted since the module last became active. This is the receive-side counterpart to RSA encryption, typically reflecting incoming key-exchange material from peers, so its activity pattern should mirror short bursts tied to session setup rather than continuous bulk traffic. A burst in this counter coinciding with a known certificate rollover event across a fleet of peers would confirm those peers are re-establishing sessions using RSA-based key exchange as expected.
