1. View the supervisor configuration file

For example: /etc/supervisor/conf.d/supervisor-mysite.conf

1. [program:mysite]
2. command =/usr/local/bin/gunicorn — bind unix:/tmp/www.sweeneys.cn.socket mysite.wsgi:application
3. directory=/home/Sweeneys/www/mysite
4. user=Sweeneys
5. autostart= true
6. autorestart= true
7. stopasgroup= true
8. killasgroup= true
9. redirect_stderr= true
10. stdout_logfile_maxbytes=200MB
11. stdout_logfile_backups=10
12. stdout_logfile =/var/log/supervisor/mysite-supervisor.log

Then you can see that the name of the program is: mysite

2. Use supervisorctl tail
