This is Ruby library that fetches and wraps memcached stats output.
Usage is simple:
mcs = MemcacheStat.new
mcs.get_hits # => 2
mcs.total_connections # => 34
To refresh the statistics:
mcs.refresh!
By default, it connects to localhost:11211. If you need a different host or port:
mcs = MemcacheStat.new("1.2.3.4", "11222")
