title: Comprehensive methods of viewing memory usage on Solaris
body: <p>On Linux, the "top" command shows a detailed but high level overview of your memory usage, showing:</p>
  
  <p>Total Memory, Used Memory, Free Memory, Buffer Usage, Cache Usage, Swap size and Swap Usage.</p>
  
  <p>My question is, what commands are available to show these memory usage figures in a clear and simple way? Bonus points if they're present in the "Core" install of Solaris. 'sar' doesn't count :)</p>
