sysstat is thought to be a complementary tool in the list of utilities included in Solaris for system observation (prstat, vmstat, iostat, mpstat, nfsstat, netstat, …). It provides an overall view of the current system performance. Its key feature is to present all most important performance metrics to the user at a single glance. Use it to get a general idea of what is happening on the system. If you encounter any bottlenecks, please ask the standard board utilities for more detailed statistics to find out what is going on. sysstat might point you into the right direction, but it probably won’t be able to give you all the information you need in more complex scenarios.
