在开发中使用resque和rufus Scheduler两次执行该作业

Question

I am working with resque and rufus scheduler.

I have created two different queues for the two different resque jobs and able to execute both the queues.

But I am facing one issue as both the queues are executing twice every time.

Here is the Scheduler.rb file :

Directory : config/initializers/scheduler.rb

require 'rubygems'
require 'rufus/scheduler'

scheduler = Rufus::Scheduler.new

scheduler.cron '46 19 * * *' do
  Resque::Job.create(:monitoring_queue, Monitoring)
end

scheduler.every '60m' do
  Resque::Job.create(:execute_monitoring_queue, ExecuteMonitor)
end

Here is the resque job file-1 monitoring.rb

class Monitoring
  @queue = :monitoring_queue
  def self.perform()
    begin
      Monitor.check_and_confirm
      NotificationMailer.notification_email.deliver
    rescue Exception => e
      puts e.message
      e.backtrace.join("\n")
    end
  end
end

Here is the resque job file-2 execute_monitor.rb

class ExecuteMonitor
  @queue = :execute_monitoring_queue
  def self.perform()
    begin
      Monitor.confirm_and_check
      NotificationMailer.notification_email.deliver
    rescue Exception => e
      puts e.message
      e.backtrace.join("\n")
    end
  end
end

can any please tell me why those queues are executing twice every time or is there something that I am missing.

Just let me know anything needed.

Not directly an answer, but could help:

• Issue with rufus-scheduler when we have multiple EC2 instances
• Rufus scheduler running multiple times with unicorn, fixed with :lockfile, but how to eliminate the error msg?
• rufus-scheduler runs scheduler multiple times due to unicorn workers
