diagnose system top

Use this command to view a list of the most system-intensive processes and to change the refresh rate.

Syntax

diagnose system top [delay <integer>]

delay

Refresh interval (seconds).

Once you execute this command, it continues to run and display in the CLI window until you enter q (quit).

While the command is running, you can press Shift + P to sort the five columns of data by CPU usage (the default) or Shift + M to sort by memory usage.

Example

This example displays a list of the top system processes and sets the update interval at 10 seconds.

FortiADC-VM # diagnose system top ?

delay refresh display period

FortiADC-VM # diagnose system top delay ?

<delay> delay in seconds

FortiADC-VM # diagnose system top delay 30

The first line indicates the up time. The second line lists the processor and memory usage, where the parameters from left to right mean:

• U — Percent of user CPU usage (in this case 0%)
• S — Percent of system CPU usage (in this case 1%)
• I — Percentage of CPU idle (in this case 97%)
• T — Total memory in kilobytes (in this case 1620 KB)
• F — Available memory in kilobytes (in this case 613 KB)

The five columns of data provide the process name (such as updated), the process ID (pid), the running status, the CPU usage, and the memory usage. The status values are:

• S — Sleeping (idle)
• R — Running
• Z — Zombie (crashed)
• < — High priority
• N — Low priority
