You could try to 'define' it on TCP level. Look with "netstat -nf inet"
for those lines, where the source host/port matches your cache. The number
of lines in state ESTAB(LISHED) are the number of concurrent clients
connected to your cache. For a nifty output, look at:

And DO NOT worry about TIME_WAITs of up to 60 % of all connection states.
