Description
This article describes advanced options on how to work with the troubleshooting tool 'diagnose sys top-summary' and all of its capabilities.
The top-summary command was deprecated on FOS 6.4x and onwards.
Scope
FortiGate.
Solution
diagnose sys top-summary ‘<options>’
OPTIONS:
-n LINES OR --num=LINES | Number of top processes to show (20 by default)
-i INTERVAL OR --interval=INTERVAL | Update interval, in seconds (1 by default)
-s SORT OR --sort=SORT | Sort mode: [cpu_percent (default)|mem|fds|pid]
-h OR --help | show this help message and exit
After the 'diagnose sys top-summary' command is running, here are the options:
h OR ? - print the list of all available commands
q OR Ctrl C – quit
m - sort by the memory consumption
c - sort by the CPU percentage
f - sort by the number of open file descriptors
p - sort by PID
k OR <Up> - go up in the list of the processes
j OR <Down> - go down in the list of the processes
<Enter> or <Space> - toggle the process tree
LEGEND:
* - indicator of the line currently active.
^ - indicator of what parameter the output is sorted in descending order.
EXAMPLE:
diagnose sys top-summary ‘-n 5 --sort=mem’
CPU [| ] 4.8%
Mem [||||||||||||||||||||| ] 54.0% 1100M/2012M
Processes: 5 (running=1 sleeping=106)
PID RSS CPU% ^MEM% FDS TIME+ NAME
* 150 67M 0.0 3.4 22 01:11.84 httpsd [x4]
171 57M 0.0 2.8 100 00:21.99 wad [x6]

159 41M 0.0 2.1 26 00:48.88 forticron
The output shows 5 lines of output which is sorted in descending order by memory utilization.
Now, press ‘c’ to sort processes by CPU utilization, press <down> 4 times to select the miglogd parent instance and press <enter> to see details of the child instance
