And the metrics _will_ be available on the same host as pmcd using -h 
local: (default for most tools, but not pmchart I just discovered) 
because the connection uses a local domain socket and the access control 
rules are relaxed compared to connection to pmcd via an ip socket (like 
a remote pmlogger uses).
