Syntax (Routing Matrix)

show system processes
<brief | detail | extensive | summary>
<all-lcc | lcc number | scc>
<wide>

Release Information

Command introduced before JUNOS Release 7.4.

Description

Display information about software processes that are running on the router and that have controlling terminals.

Options

none — Display standard information about system processes.

all-lcc — (Routing matrix only) (Optional) Display standard system process information for all T640 routing nodes (or line-card chassis) connected to a TX Matrix platform.

brief | detail | extensive | summary — (Optional) Display the specified level of detail.

lcc number — (Routing matrix only) (Optional) Display standard system process information for a specific T640 routing node that is connected to a TX Matrix platform. Replace number with a value from 0 through 3.

scc — (Routing matrix only) (Optional) Display standard system process information for the TX Matrix platform (or switch-card chassis).

wide — (Optional) Display process information that might be wider than 80 columns.

Additional Information

By default, when you issue the show system processes command on a TX Matrix master Routing Engine, the command is broadcast to all the T640 master Routing Engines connected to it. Likewise, if you issue the same command on the TX Matrix backup Routing Engine, the command is broadcast to all the T640 backup Routing Engines that are connected to it.

Output Fields

Table 126 describes the output fields for the show system processes command. Output fields are listed in the approximate order in which they appear.

Table 126: show system processes Output Fields

Field Name

Field Description

Level of Output

last PID

Last process identifier assigned to the process.

brief extensive summary

load averages

Three load averages followed by the current time.

brief extensive summary

processes

Number of existing processes and the number of processes in each state (sleeping, running, starting, zombies, and stopped).

brief extensive summary

Mem

Information about physical and virtual memory allocation.

brief extensive summary

Swap

Information about physical and virtual memory allocation.

brief extensive summary

PID

Process identifier.

detail extensive summary

TT

Control terminal name.

none detail

STAT

Symbolic process state. The state is given by a sequence of letters. The first letter indicates the run state of the process:

  • D—In disk or other short-term, uninterruptible wait
  • I—Idle (sleeping longer than about 20 seconds)
  • R—Runnable
  • S—Sleeping for less than 20 seconds
  • T—Stopped
  • Z—Dead (zombie)
  • + —The process is in the foreground process group of its control terminal.
  • < —The process has raised CPU scheduling priority.
  • > —The process has specified a soft limit on memory requirements and is currently exceeding that limit; such a process is not swapped.
  • A—The process requested random page replacement.
  • E—The process is trying to exit.
  • L—The process has pages locked in core.
  • N—The process has reduced CPU scheduling priority.
  • S—The process requested first-in, first-out (FIFO) page replacement.
  • s—The process is a session leader.
  • V—The process is temporarily suspended.
  • W—The process is swapped out.
  • X—The process is being traced or debugged.

none detail

UID

User identifier.

detail

USERNAME

Process owner.

extensive summary

PPID

Parent process identifier.

detail

CPU

(D) — Short-term CPU usage. (E and S) — Raw (unweighted) CPU usage. The value of this field is used to sort the processes in the output.

detail extensive summary

RSS

Resident set size.

detail

WCHAN

Symbolic name of the wait channel.

detail

STARTED

Local time when the process started running.

detail

PRI

Current priority of the process. A lower number indicates a higher priority.

detail extensive summary

NI or NICE

UNIX "niceness" value. A lower number indicates a higher priority.

detail extensive summary

SIZE

Total size of the process (text, data, and stack), in kilobytes.

extensive summary

RES

Current amount of resident memory, in kilobytes.

extensive summary

STATE

Current state of the process (for example, sleep, wait, run, idle, zombie, or stop).

extensive summary

TIME

(S) — Number of system and user CPU seconds that the process has used.(None, D, and E) — Total amount of time that the command has been running.

detail extensive summary

WCPU

Weighted CPU usage.

extensive summary

COMMAND

Command that is currently running.
