NAME
     prstat - report active process statistics

SYNOPSIS
     prstat [-acJLmRtTv] [-C psrsetlist] [-j projlist] [-k  task-
     list]  [-n ntop[,nbottom]] [-p pidlist] [-P cpulist] [-s key
     | -S key ] [-u euidlist] [-U uidlist] [interval [count]]

DESCRIPTION
     The prstat utility iteratively examines all active processes
     on  the  system and reports statistics based on the selected
     output mode and sort order. prstat provides options to exam-
     ine  only  processes matching specified PIDs, UIDs, CPU IDs,
     and processor set IDs.

     The -j, -k, -C, -p, -P, -u, and -U options accept  lists  as
     arguments. Items in a list can be either separated by commas
     or enclosed in quotes and separated by commas or spaces.

     If you  do  not  specify  an  option,  prstat  examines  all
     processes and reports statistics sorted by CPU usage.

OPTIONS
     The following options are supported:

     -a    Report information about processes and users. In  this
           mode  prstat displays separate reports about processes
           and users at the same time.

     -c     Print new reports below previous reports  instead  of
           overprinting them.

     -C psrsetlist
            Report only processes or lwps that are bound to  pro-
           cessor  sets  in the given list. Each processor set is
           identified by an integer as reported by psrset(1M).

     -j projlist
           Report only processes or lwps whose project ID  is  in
           the  given  list.  Each project ID can be specified as
           either a project name or a numerical project ID.   See
           project(4).

     -J    Report information about processes  and  projects.  In
           this  mode  prstat  displays  separate  reports  about
           processes and projects at the same time.

     -k tasklist
           Report only processes or lwps  whose  task  ID  is  in
           tasklist.

     -L    Report statistics for each light-weight process (LWP).
           By default, prstat reports only the number of LWPs for
           each process.

     -m    Report microstate process accounting  information.  In
           addition  to  all  fields listed in -v mode, this mode
           also includes the percentage of time the  process  has
           spent  processing system traps, text page faults, data
           page faults, waiting for user locks  and  waiting  for
           CPU (latency time).

     -n ntop[,nbottom]
           Restrict number of output  lines.  The  ntop  argument
           determines how many lines of process or lwp statistics
           are reported, and the nbottom argument determines  how
           many  lines  of user, task, or projects statistics are
           reported if the -a, -t, -T, or -J options  are  speci-
           fied.  By default, prstat can display as many lines of
           output as will fit within a window or terminal.

     -p pidlist
            Report only processes whose  process  ID  is  in  the
           given list.

     -P cpulist
           Report only processes or lwps which have most recently
           executed on a CPU in the given list. Each CPU is iden-
           tified by an integer as reported by psrinfo(1M).

     -R    Put prstat in the real  time  scheduling  class.  When
           this  option  is  used,  prstat is given priority over
           time-sharing and interactive processes. This option is
           available only for superuser.

     -s key
           Sort output lines (that is, processes, lwps, or users)
           by  key  in descending order. Only one key can be used
           as an argument.

           There are five possible key values:

           cpu   Sort by process CPU usage. This is the default.

           time  Sort by process execution time.

           size  Sort by size of process image.

           rss   Sort by resident set size.

           pri   Sort by process priority.

     -S key
           Sort output lines by key in ascending order.  Possible
           key values are the same as for the -s option. See -s.

     -t    Report total usage summary for each user. The  summary
           includes  the  total number of processes or LWPs owned
           by the user,  total  size  of  process  images,  total
           resident  set size, total cpu time, and percentages of
           recent cpu time and system memory.

     -T    Report information about processes and tasks. In  this
           mode  prstat displays separate reports about processes
           and tasks at the same time.

     -u  euidlist
           Report only processes whose effective user  ID  is  in
           the  given  list.  Each  user  ID  may be specified as
           either a login name or a numerical user ID.

     -U  uidlist
           Report only processes whose real user  ID  is  in  the
           given  list. Each user ID may be specified as either a
           login name or a numerical user ID.

     -v    Report  verbose  process  usage.  This  output  format
           includes  the percentage of time the process has spent
           in user mode, in system mode, and  sleeping.  It  also
           includes  the number of voluntary and involuntary con-
           text switches, system calls and the number of  signals
           received.
