Structuring `cfengine.conf'

The structure of `cfengine.conf' needs to reflect your policy for running jobs on the system. You need to switch on relevant tasks and switch off unwanted tasks depending on the time of day. This can be done in three ways:

• By placing individual actions under classes which restrict the times at which they are executed,

  
    action:
  
          Hr00.Min10_15||Hr12.Min45_55::
  
             Command
  
  

• By choosing a different actionsequence depending on the time of day.

  
    control:
  
          Hr00::   # Action-sequence for daily run at midnight
  
             actionsequence = ( sequence )
  
         !Hr00::   # Action-sequence otherwise
  
              actionsequence = ( sequence )
  
  

• By importing modules based on time classes.

  
    import:
  
          Hr00:: cf.dailyjobs
  
          any::  cf.hourlyjobs
  
  

The last of these is the most efficient of the three, since cfengine does not even have to spend time parsing the files for actions which you know you will not want.
