diagnose system top
Use this command to display:
- Up time (run time).
- Current total processor and memory usage.
- Current free memory.
- The most resource-intensive system processes and daemons showing their memory (RAM) and processor (CPU) usage.
The first two lines of the display indicate the up time, and the processor and memory usage. Processor and memory usages on the second line have abbreviated labels shown below in bold.
Run Time: 0 days, 21 hours and 3 minutes
0U, 4S, 95I; 1035792T, 646920F

Letter |
Description |
|---|---|
|
U |
User CPU usage (%) |
|
S |
System CPU usage (%) |
|
I |
Idle CPU usage (%) |
|
T |
Total memory (KB) |
|
F |
Free memory (KB) |
The remaining lines contain the process list, which has the following columns:
Column 1 is the process name, such as SSHD.
Column 2 is the process ID (PID) number, such as 731.
Column 3 is the status:
- S: Sleeping (idle)
- R: Running
- Z: Zombie (crashed)
You might be able to restart a zombie process without rebooting. See Execute commands.
- <: High priority
- N: Low priority
Column 4 is CPU usage (%).
Column 5 is memory usage (%).
When the command is running, you can sort the process list. The default sort order is by CPU usage.
- Shift + P: Sort by CPU usage.
- Shift + M: Sort by memory usage.
Process list output displays in your CLI window until you stop it by pressing q or Ctrl + C.

Example
This example refreshes the display of the top 19 most system-intensive processes every five seconds. The output indicates that FortiAI is mostly idle except for some processor resources used by a connection to the web UI (admin.fe) and to the CLI.
