Step 1: Display Information about Software Processes

Purpose

Display information about software processes to begin diagnosing an error condition.

Action

To display information about the software processes that are running on the router, use the following JUNOS CLI operational mode command:

user@host> show system processes extensive

Sample Output

user@host> show system processes extensive
last pid: 750; load averages: 0.00, 0.00, 0.00 up 0+00:58:50 18:34:17
52 processes: 1 running, 51 sleeping

Mem: 50M Active, 19M Inact, 38M Wired, 264K Cache, 86M Buf, 642M Free
Swap: 768M Total, 768M Free

What It Means

The sample output shows the central processing unit (CPU) utilization and lists the processes in order of CPU utilization.

Table 17 lists and describes the output fields included in the sample output for the show processes extensive command. The fields are listed in alphabetical order.

Table 17: Show System Processes Extensive Output Fields

Field	Description
COMMAND	Command that is running.
CPU	Raw (unweighted) CPU usage. The value of this field is used to sort the processes in the output.
last pid	Last process identifier assigned to the process.
load averages	Three load averages, followed by the current time.
Mem	Information about physical and virtual memory allocation.
NICE	UNIX "nice" value. The nice value allows a process to change it's final scheduling priority.
PID	Process identifier.
PRI	Current kernel scheduling priority of the process. A lower number indicates a higher priority.
processes	Number of existing processes and the number of processes in each state (sleeping, running, starting, zombies, and stopped).
RES	Current amount of resident memory, in KB.
SIZE	Total size of the process (text, data, and stack), in KB.
STATE	Current state of the process (sleep, wait, run, idle, zombi, or stop).
Swap	Information about physical and virtual memory allocation.
USERNAME	Owner of the process.
WCPU	Weighted CPU usage.
