Of course, those will only tell you whether or not the port is listening or connected, it won't tell you anything about performance. You can use snoop if the packets are actually going over the wire. Inter-zone traffic is not snoopable in Solaris 10, although this feature is available in OpenSolaris.  Another possibility is to use dtrace. Again, the timing is off, since the dtrace IP provider is not available in Solaris 10, only OpenSolaris and the one thing that would really help is the TCP provider but that is not yet available in either version. Soon though.

Using truss on the application and dtrace are probably your best bets.
