我正在使用monit gem监视我的sidekiq进程 我的Monitrc配置文件：-
check process sidekiq_process with pidfile /home/path_to_pid
start program = "bundle exec sidekiq -d -L log/sidekiq.log -C config/sidekiq.yml -e development" with timeout 60 seconds
stop program = "bundle exec sidekiq -d -L log/sidekiq.log -C config/sidekiq.yml -e development"
我的sidekiq.yml文件：-
development:
:pidfile: tmp/pids/sidekiq_development.pid
:logfile: log/sidekiq_development.log
:concurrency: 1
使用bundle exec sidekiq -d -L log/sidekiq.log -C config/sidekiq.yml -e development运行sidekiq然后运行sudo monit之后，sudo monit status会给我以下信息：-
Process 'sidekiq_process'
status Running

因此，它的监视很好，当我杀死sidekiq进程时，它甚至向我发送“不存在”邮件，但问题是在sidekiq进程被杀死之后，它也应该重新启动该进程。这是sudo monit status在杀死sidekiq之后给我的东西
Process 'sidekiq_process'
status Execution failed
monitoring status Monitored

我还收到一封邮件，指出“执行失败”。
为什么我会收到执行失败的错误，为什么进程无法通过monit重新启动？
