show processes command

If your Cisco device is experiencing high CPU usage, we can use the Show Operations command to list all running processes and determine the cause of the problem. This command provides you with a list of active processes, along with corresponding process ID, priority, user CPU time, number of times recalled, and other information.

Here is an example output of this command invoked on a Cisco router:

The first line of the output shows the CPU usage in the last 5 seconds, 1 minute and 5 minutes. Here are other fields described in the output: PID: the process identifier.

Q: The process queue priority. Possible values ​​are: C (critical), H (high), M (medium), and L (low).

Ty: Diagram test (case). Possible values ​​are: * (currently running), E (waiting for an event), S (ready to run, processor abandoned voluntarily), rd (ready to run, trigger conditions occurred), we (waiting for an event), sa (sleep Until absolute time), si (sleep for a period of time), sp (sleep for a period of time (alternative call), st (sleep until the end of time), hg (suspended; process never gets started again), xx (dead: process ended , But not yet removed).

Computer - the current program counter.

Execution time: The CPU time that the process used.

Called: The number of times the process was called.

microSecs: CPU time for each call.

Stack - low watermark or total stack space available, shown in bytes.

TTY: A terminal that controls the process.

Process: The name of the process.
