Showing Software Processes

To verify system operation or to begin diagnosing an error condition, you may need to display information about software processes running on the router.

To show software processes:

Make sure you are in operational mode.
Type the following command:

This command shows the central processing unit (CPU) utilization on the router and lists the processes in order of CPU utilization. For example:

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

Table 10 lists and describes the output fields included in this example. The fields are listed in alphabetical order.

Table 10: show system process Command 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 its 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.
