使用monit监控工具设置Delayed_job

Question

我正在部署 Rubyonrails Web 应用程序，其中包含 ruby​​ 1.9.2p280、rubyonrails 3.07，其中包含 apache乘客和delayed_job作为后台作业。

我想监控我的乘客以及delayed_job后台作业。

我找不到任何分步指南。

非常感谢你

如下所述添加以下 .monitrc 文件并运行命令 monit reload 加载配置。

/etc/monit/web.monitrc

check process apache with pidfile /var/run/apache2.pid
  start program = "/etc/init.d/apache2 start"
  stop program  = "/etc/init.d/apache2 stop"
  if cpu > 80% for 5 cycles then restart
  if totalmem > 300.0 MB for 5 cycles then restart
  if children > 250 then alert
  if failed port 80 with timeout 10 seconds then restart
  if 3 restarts within 5 cycles then timeout
  mode manual
  group web

/etc/monit/delayed_job.monitrc

check process delayed_job with pidfile /mnt/<project>/tmp/pids/delayed_job.pid
  start program = "/usr/bin/delayed_job_start"
  stop program = "/usr/bin/delayed_job_stop"
  mode manual
  group delayed_job

/usr/bin/delayed_job_start

#!/bin/sh

cd /mnt/<project> && RAILS_ENV=production ruby script/delayed_job start
