It's a matter of the plugin collecting the stats, not collectd itself
(you try to use the filter plugins to rewrite the host, see

If memcached cannot set host from its configuration you are unlucky (though
you may patch collectd's memcached plugin to allow configuring the host
for which it reports the stats).
