  20 .SH DESCRIPTION
  21 .sp
  22 .LP
  23 The \fBprstat\fR utility iteratively examines all active processes on the
  24 system and reports statistics based on the selected output mode and sort order.
  25 \fBprstat\fR provides options to examine only processes matching specified
  26 \fBPID\fRs, \fBUID\fRs, zone \fBID\fRs, \fBCPU\fR \fBID\fRs, and processor set
  27 \fBID\fRs.
  28 .sp
  29 .LP
  30 The \fB-j\fR, \fB-k\fR, \fB-C\fR, \fB-p\fR, \fB-P\fR, \fB-u\fR, \fB-U\fR, and
  31 \fB-z\fR options accept lists as arguments. Items in a list can be either
  32 separated by commas or enclosed in quotes and separated by commas or spaces.
  33 .sp
  34 .LP
  35 If you do not specify an option, \fBprstat\fR examines all processes and
  36 reports statistics sorted by \fBCPU\fR usage.

  73 of the specified processor sets (see \fBpset_getloadavg\fR(3C)). Processes with

 865 The snapshot of system usage displayed by \fBprstat\fR is true only for a
 866 split-second, and it may not be accurate by the time it is displayed. When the
 867 \fB-m\fR option is specified, \fBprstat\fR tries to turn on microstate
 868 accounting for each process; the original state is restored when \fBprstat\fR
 869 exits. See \fBproc\fR(4) for additional information about the microstate
 870 accounting facility.

 873 The total memory size reported in the SWAP and RSS columns for groups of
