This counts connection attempts specifically matching the Kazaa peer-to-peer protocol. This lets an admin enforcing a no-P2P policy see exactly how much of the blocked P2P traffic is Kazaa specifically, and given Kazaa's decline since the mid-2000s, a persistently nonzero count on a modern network is worth investigating as a possible signature false positive rather than assumed to be real Kazaa usage. For example, this counter staying at zero on most modern networks, with any nonzero reading worth a closer look.
