In this article, I will take you through 13 Popular Unix prstat command examples. You might have used top command in Unix based system to check the memory and cpu utilization but what will you do when i will ask to check the zones cpu and memory utilization ? There comes prstat command to our rescue which can provide zone wise utilization report. This command will also show User based and PID based utilization. You can also use prstat command to find out the process causing memory and cpu spike regularly and can cap/adjust your utilization as per your requirements. We will go through all the prstat command usages in below examples.
Below are the terminology used in prstat command output.
- PID : The process ID of the process.
- USERNAME : The real user (login) name or real user ID.
- SWAP: The sum of swap reservations of the associated processes for each user, project, task, or zone.
- RSS : The resident set size of the process (RSS), in kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T).
- STATE: The state of the process
- PRI : The priority of the process. Larger numbers mean higher priority.
- NICE : Nice value used in priority computation. Only processes in certain scheduling classes have a nice value.
- TIME : The cumulative execution time for the process.
- CPU : The percentage of recent CPU time used by the process.
- PROCESS: The name of the process (name of executed file).
- LWPID: The lwp ID of the lwp being reported.
- NLWP: The number of lwps in the process.
- NPROC: Number of processes in a specified collection.
- MEMORY: Percentage of memory used by a specified collection of processes.
- USR: The percentage of time the process has spent in user mode.
- SYS: The percentage of time the process has spent in system mode.
- TRP: The percentage of time the process has spent in processing system traps.
- TFL: The percentage of time the process has spent processing text page faults.
- DFL: The percentage of time the process has spent processing data page faults.
- LCK: The percentage of time the process has spent waiting for user locks.
- SLP: The percentage of time the process has spent sleeping.
- LAT: The percentage of time the process has spent waiting for CPU.
- VCX: The number of voluntary context switches.
- ICX: The number of involuntary context switches.
- SCL: The number of system calls.
- SIG: The number of signals received.
- LGRP: The home lgroup of the process or lwp.

Example 10: How to report information about all processes and users using prstat command
If you want to show information about all the processes and users then you need to use prstat -a command as shown below. This command will show memory and cpu utilization based on Process ID as well as for Users in a separate section.
