prstat – a great tool for process monitoring

Solaris administrators with solid Linux experience are usually installing top on their systems because of convenience. Quite a few administrators are aware of prstat but don't see benefits of using its format which somewhat differs from top. And a really small number of Solaris sysadmins really know how to use the prstat command properly. I consider myself a power user, so won't even be claiming to be a prstat guru, but these command examples will hopefully teach you a thing or two.


prstat advantages at glance

I really like prstat because it gives me access to the following information:

  • microstate accounting with LOTS of CPU info
  • CPU usage stats across global and non-global zones
  • provide reports (multiple screens of stats taken at specific intervals) forwarded to a file
  • do really useful summaries about top users consuming your OS resources
