Supervisord action if service restart - linux

Question

I want to create a file when the service is restarted.
rpm -qa | grep super
supervisor-3.1.3-0.5.b1.el6.noarch
My config file:
[program:tests]
command=/root/while.sh
directory=/root
user=root
autostart=true
autorestart=true
[eventlistener:tests_ls]
command=touch /tmp/32
events=PROCESS_STATE
My log file error

supervisorctl

Where did I go wrong?
