Description

This article describes how to identify and restart a specific process in FortiADC.

Scope

FortiADC .

Solution

Identify the process with this command:

diagnose sys top

Locate the PID. As an example, try to kill PID 3788:

diagnose sys top
Mem: 6471716K used, 1502144K free, 4303094K shrd, 446376K buff, 3140776K cached
CPU: 28.5% usr 33.3% sys 0.0% nic 38.0% idle 0.0% io 0.0% irq 0.0% sirq
Load average: 1.19 1.24 1.20 4/300 11194
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
3788 1 root R 685m 8.8 1 47.5 httproxy -f /tmp/vs/root/VS_simit_fcm_org_co.0.httproxy.cfg <- This one.
2840 2576 root R 68988 0.8 0 9.5 keepalived: checker
8808 2 root IW 0 0.0 1 4.7 [kworker/1:1]
2453 1 root S 1633m 20.9 0 0.0 /bin/mysqld --defaults-file=/etc/mysql/my.cnf --skip-grant-tables --skip-networking --user=root
2468 1 root S 1460m 18.7 0 0.0 /bin/restapi 1
2469 1 root S 1439m 18.4 1 0.0 /bin/restapi 2

Enable the shell mode in the FortiADC setting. As an example, user 'ert' and password 12345:

config system global
set shell-access enable
set shell-username ert
set shell-password 12345
set shell-timeout 200
end

Then, access it as follows:

ssh ert@x.x.x.x <- Where x.x.x. is the IP address of the FortiADC.

Validate the access in shell mode as below:

~# whoami
ert

To kill a process like this, apply the following command in shell mode:

kill 3788

If any process still causes issues after killing, open a TAC ticket.
