While Ganeti executes the job, `snf-ganeti-eventd`, `snf-ganeti-hook` and


  		





  849
  
  
    
`snf-progress-monitor` are monitoring the progress of the job and send


  		





  850
  
  
    
corresponding messages to the RabbitMQ servers. These components are part

of `snf-cyclades-gtools` and must be installed on all Ganeti nodes. Specially:

* *snf-ganeti-eventd* sends messages about operations affecting the operating

  state of instances and networks. Works by monitoring the Ganeti job queue.

* *snf-ganeti_hook* sends messages about the NICs of instances. It includes a

  number of `Ganeti hooks <http://docs.ganeti.org/ganeti/2.2/html/hooks.html>`_

  for customisation of operations.
