We have a cluster of 3 master nodes and 2 data nodes. If run support-diagnostics on any one of the node as "./diagnostics.sh --host master1 -o /root/diag-out"  
does it collect stats and logs from all nodes?

or Can i pass list of node hostnames?

or should i run multiple instances of this command with different hostnames?
