Seems like the best option to me (and not allowing the uncore events
for the other commands)

But I  don't like "node" because in a non NUMA kernel you won't have nodes, 
but this is still useful. Or with NUMA emulation you may have nodes
that doesn't match the sockets.

Maybe perf package or perf socket ?
