Usually a diagnostic session wants to check the local state
without this flag the network is joined and left every iteration
altering actually the daemon status.
Also if the diagnostic client is used against a live node, the
network leave has a very bad side effect of kicking the node
out of the network killing its internal status.
For the above reason introducing the flag -a to be explicit
so that the current state is always preserved
