del_nodes(Count :: non_neg_integer(), Graceful :: boolean()) ->

Deletes Scalaris nodes from the current VM.

Delete a single node.
wait_for_stable_ring(NrOfNodes :: non_neg_integer()) -> ok
check_ring() -> {error, string()} | ok
Contact mgmt server and check that each node's successor and predecessor are correct.
check_ring_deep() -> ok | check_ring_deep_error()
Contact mgmt server and check that each node's successor and predecessor lists are correct.

number_of_nodes() -> non_neg_integer() | timeout
get_dump() ->
{Received :: comm_logger:stat_tree(),
Sent :: comm_logger:stat_tree(),
erlang_timestamp()}
returns communications information. the comm-layer logs for each message-tag how many message were sent and how large were these messages in total. get_dump/0 returns a map from message-tag to message-count and message-size and a timestamp when the measurement was started.
get_dump_bw() ->
{Received :: [{atom(), float(), float()}],
Sent :: [{atom(), float(), float()}]}
returns communications information. similar to get_dump/0 it returns message statistics per message-tag, but it scales all values by the elapsed time. so it returns messages per second and bytes per second for each message-tag
diff_dump(Before :: comm_logger:stat_tree(), After :: comm_logger:stat_tree()) -> [{Tag :: atom(), Size :: integer(), Count :: integer()}]
