использование monit для управления временем отклика node.js pm2

Я хочу использовать monit за возможность перезаряжать pm2 node.js сайт, если ответ превышает 2 секунды.

Это моя конфигурация монитора /etc/monit/monitrc:

check process pm2 with pidfile "/root/.pm2/pids/siteName9000.pid" 
        start program = "/usr/local/bin/pm2 start ~/pathToNodeApp/9000/app.js --name siteName9000" 
        stop program  = "/usr/local/bin/pm2 stop siteName9000" 
        if failed port 9000 protocol HTTP 
            request / 
            with timeout 2 seconds 
            then restart

Затем в консоли запускаю:

# monit restart pm2

Затем в консоли запускаю:

# monit -d 10 -c /etc/monit/monitrc

делать эту проверку каждые 10 секунд.

Затем в журнале мониторинга /var/log/monit.log Я вижу:

[MSK May 18 06:57:05] info     : 'pm2' restart on user request
[MSK May 18 06:57:05] info     : monit daemon with PID 22480 awakened

Итак, моя конфигурация монитора не работает.
