Resource usage
Each program running on a computer has one or more processes associated with it. For example if you open a Telnet program, it will have an associated telnet process. The same is true in FortiOS. All the processes have to share the system resources in FortiOS including memory and CPU.
Use get system performance status command to show the FortiOS performance status.
Sample output:
FGT#get system performance status
CPU states: 0% user 0% system 0% nice 100% idle
CPU0 states: 0% user 0% system 0% nice 100% idle
CPU1 states: 0% user 0% system 0% nice 100% idle
CPU2 states: 0% user 0% system 0% nice 100% idle
CPU3 states: 0% user 0% system 0% nice 100% idle
Memory states: 25% used
Average network usage: 0 kbps in 1 minute, 0 kbps in 10 minutes, 0 kbps in 30 minutes
Average sessions: 5 sessions in 1 minute, 5 sessions in 10 minutes, 4 sessions in 30 minutes
Average session setup rate: 0 sessions per second in last 1 minute, 0 sessions per second in last 10 minutes, 0 sessions per second in last 30 minutes
Virus caught: 0 total in 1 minute
IPS attacks blocked: 0 total in 1 minute
Uptime: 0 days, 12 hours, 7 minutes
Monitor the CPU/memory usage of internal processes using the following command:
get system performance top <delay> <max_lines>
The data listed by the command includes the name of the daemon, the process ID, whether the process is sleeping or running, the CPU percentage being used, and the memory percentage being used.
Sample output:
FGT#get system performance top 10 100
Run Time: 0 days, 11 hours and 30 minutes
