I have two identical Unix servers (Oracle T5-2, Solaris 11.2) and I want to do some testing of the network redundancy/failover I've configured (which I hope I've done right).
Each server has four network ports.
Two ports on server 1 and two ports on server 2 are connected to switch 1. Two ports on server 1 and two ports on server 2 are connected to switch 2.
I want to do something like this: root@srv1:~# pv </dev/zero | ssh root@srv2 'cat >/dev/null' and get a running throughput rate while I unplug and replug cables, BUT I'd like to have four simultaneous streams and four running totals. I don't know how to do this. I'd rather not have four separate sessions open to see this. I just want to have one session that looks like
448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ] 448MB 0:00:09 [ 112MB/s] [ <=> ]
Or similar. Any suggestions?
