memcached monitoring script

Hello all,

I'm using your script for some weeks now but no graph displays. I simply follow your directives (add a line in hobbitserver.cfg, add a graph definition into hobbitgraph.cfg) and as a result I have a simple line "hobbit graph ncv:mcache" with a magnifier near it. The rrd database is filling up and looks good :
