Question

是否可以使用God ruby gem监控jruby程序？任何工作示例都会有所帮助。这是我到目前为止所尝试的，但它不起作用。

这是神文件start_app.god

God.watch do |w|
  w.name = "simple"
  w.start = "jruby /path/to/my_jruby/my_jruby.rb"
  w.keepalive
end

以下是我运行god -c start_app.god -D

时的日志

请注意，simple moved 'start' to 'up'语句不断重复，意味着上帝无法启动my_jruby.rb脚本。

有谁知道这个问题的原因？如果无法使用God完成此操作，可能的替代方案是什么？

使用神宝石监控JRuby进程
