sun solaris 11.2 sysstat

I've sun solaris 11.2 and I want to install and use sysstat and use it the way I use it on linux-ubuntu to monitor some activities and run cpu and memory checks for certain time intervals. I was looking in the internet i couldn't find sysstat for solaris, so could you please help me how to install on solaris if exists if not, is there any other simple command or utility that I can use to monitor the cpu and memory. Thanks in advance.
