Is it per IP? I am not an SNMP expert, but I believe SNMP cacheClients is "Number of clients accessing cache" on the Cache Manager mgr:info page (you can check by correlating SNMP and mgr:info output). If you are using SMP Squid (e.g., multiple Squid workers), please see the "Number of clients accessing cache" table row at http://wiki.squid-cache.org/Features/CacheManager#SMP_considerations HTH, Alex.
