The mem_allocated stat reports the amount of memory allocated for the system (not just Erlang). This number is returned by the memsup module: http://erldocs.com/R14B02/os_mon/memsup.html
There are also a series of stats prefixed with "memory_" which provide memory information for the Riak node. http://erldocs.com/R14B02/erts/erlang.html#memory/0 Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc. d...@basho.com On Mon, Feb 20, 2012 at 8:05 AM, heffergm <heffe...@gmail.com> wrote: > I was hoping someone could clue me in on exactly what the mem_allocated > stat > is measuring. > > I'm running a 6 node cluster, 4gb of ram per node.
