Man, twice in a single day that I’ve been totally impressed with DTrace, and two posts from Brendan –

  • A proposal for a DTrace Network Provider, net, so you can do funky things like – 
    # dtrace -n 'tcp:::receive /args[2]->tcp_dport == 80/ {
        @pkts[args[1]->ip_daddr] = count();
}'
dtrace: description 'tcp:::receive' matched 1 probe
^C
