ruby-on-rails - 使用 monit 监控多个延迟工作的工作人员

Question

我已经阅读了很多关于使用 monit 监控延迟作业的内容。实现非常简单直接。但是，当一个工人不够用时，我如何设置 monit 以确保，比如说，10 个工人不断运行？

Answer 1

您可以为第一个工作人员复制 N 次相同的配置。假设您有 5 个工作人员，您将使用以下内容监控所有工作人员：

check process delayed_job.0
   with pidfile /path/to/shared/pids/delayed_job.0.pid
   start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job -n 5 start' - user"
   stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job stop' - user"

check process delayed_job.1
   with pidfile /path/to/shared/pids/delayed_job.1.pid
   start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job -n 5 start' - user"
   stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job stop' - user"

check process delayed_job.2
  with pidfile /path/to/shared/pids/delayed_job.2.pid
  start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job -n 5 start' - user"
  stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job stop' - user"

check process delayed_job.3
  with pidfile /path/to/shared/pids/delayed_job.3.pid
  start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job -n 5 start' - user"
  stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job stop' - user"

check process delayed_job.4
  with pidfile /path/to/shared/pids/delayed_job.4.pid
  start program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job -n 5 start' - user"
  stop program = "/bin/su -c '/usr/bin/env RAILS_ENV=production /path/to/current/script/delayed_job stop' - user"
