You may be interested in experimenting with sFlow: http://blog.sflow.com/search/label/Memcache Installing sFlow instrumentation does require a patch to the Memcached code, so probably doesn't help your current situation. FYI sFlow can also be used to instrument the web tier, there are currently implementations for Apache and NGINX http://code.google.com/p/mod-sflow/ http://code.google.com/p/nginx-sflow-module/ Cheers, Peter
