A great feature is the memory utilization graph.

It shows utilization, disk space utilization, uplink utilization, and core utilization.

The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job.

Its graphical user interface is also very easy to use and intuitive.
