很不幸運地，sidekiq 並不是一個非常可靠的 process。有時候會自己死掉，造成非常大的困擾。所以實務上還會需要額外再裝一個監控工具，如果發現它掛了，就自動重開它。
sudo apt-get install monit
edit vim /etc/monit/monitrc, 約在 118 行處將註解取消
set httpd port 2812
use address localhost # only accept connection from localhost
allow localhost # allow localhost to connect to the server and
allow admin:monit
將 sidekiq.conf (範例參考如下，請將 rails101 置換成你的APP名稱 ) 到 /etc/monit/conf.d
check process sidekiq_rails101_production0
with pidfile "/home/deploy/rails101/shared/tmp/pids/sidekiq-0.pid"
start program = "/bin/su - deploy -c 'cd /home/deploy/rails101/current && /usr/bin/env bundle exec sidekiq --index 0 --pidfile /home/deploy/rails101/shared/tmp/pids/sidekiq-0.pid --environment production --logfile /home/deploy/rails101/shared/log/sidekiq.log -d'" with timeout 30 seconds
stop program = "/bin/su - deploy -c 'cd /home/deploy/rails101/current && /usr/bin/env bundle exec sidekiqctl stop /home/deploy/rails101/shared/tmp/pids/sidekiq-0.pid'" with timeout 20 seconds
group rails101-sidekiq
輸入 sudo service monit restart 重啟 輸入 sudo monit status 可以看到應該有成功在監測 sidekiq
