服务重启时的Supervisord操作

Question

我想在重新启动服务时创建一个文件。

rpm -qa | grep super
 supervisor-3.1.3-0.5.b1.el6.noarch

我的配置文件：

[program:tests]
command=/root/while.sh
directory=/root
user=root
autostart=true
autorestart=true

[eventlistener:tests_ls]
command=touch /tmp/32
events=PROCESS_STATE

我的日志文件错误

supervisorctl
 tests                            RUNNING   pid 26378, uptime 0:09:02
 tests_ls                         FATAL     Exited too quickly (process log may have details)

我哪里出错了？
