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 OS CLI operational mode command:

Meaning
The sample output shows the central processing unit (CPU) utilization and lists the processes in order of CPU utilization.
Table 1 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 1: 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. |
