21 .SH DESCRIPTION
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.

69 Report only processes or lwps that are bound to processor sets in the given
70 list. Each processor set is identified by an integer as reported by
71 \fBpsrset\fR(1M). The load averages displayed are the sum of the load averages
72 of the specified processor sets (see \fBpset_getloadavg\fR(3C)). Processes with
73 one or more LWPs bound to processor sets in the given list are reported even
74 when the \fB-L\fR option is not used.

180 are reported if the \fB-a\fR, \fB-t\fR, \fB-T\fR, \fB-J\fR or \fB-Z\fR options
181 are specified. By default, \fBprstat\fR displays as many lines of output that
182 fit in a window or terminal. When you specify the \fB-c\fR option or direct the

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

881 The total memory size reported in the SWAP and RSS columns for groups of
882 processes can sometimes overestimate the actual amount of memory used by
883 processes with shared memory segments.
