Now, there are three main ways to handle resource management in Solaris 11: by flows, by interface, and by custom Quality of Service rules.

The QoS methods are the most flexible, but also highly complex, and perhaps best avoided unless absolutely necessary.

Related to resource management is knowing just how much data is flowing through the resource. At a coarse level, the dlstat command will tell you the amount of data that has been flowing through a low-level physical or virtual interface. Similar to the iostat command, it can show you total number of packets since reboot, or you can tell it to report over regular intervals.

At a little more refined level, is the flowstat command, mentioned in the Flow-based resource management section.
