Module: Proby::ResquePlugin

Defined in:
lib/proby/resque_plugin.rb

Overview

Automatically notifies Proby when this job starts and finishes.

class SomeJob
  extend Proby::ResquePlugin

  self.perform
    do_stuff
  end
end

The Proby Task ID can be set in one of two ways. The most common way is to put the ID in an ENV variable that is set in your crontab. This ID will be transparently passed to the Resque job via Redis.

0 0 * * * PROBY_TASK_ID=abc123 ./queue_some_job

Alternatively, if you’re not using cron and therefore don’t want that support, you can just set the @proby_id ivar in the class, like so.

class SomeJob
  extend Proby::ResquePlugin
  @proby_id = 'abc123'

  self.perform
    do_stuff
  end
end

Setting the @proby_id variable will take precendence over the ENV variable.
