Hi

We use something like this to distribute cron jobs over a specified
time interval:

define cron::interval(
  $ensure        = present,
  $start_hour    = undef,
  $length        = '60',  # interval length in minutes
  $comment       = undef,
  $command       = undef,
  $user          = 'root',
){

  $minutes_from_start = fqdn_rand($length)
  $minutes_remainder  = $minutes_from_start % 60
  $additional_hours   = ( $minutes_from_start - $minutes_remainder ) / 60

  # calculate the real values for the cronjob
  $cron_hour   = ( $start_hour + $additional_hours ) % 24
  $cron_minute = $minutes_remainder

  cron{$name:
    ensure  => $ensure,
    command => $command,
    user    => $user,
    hour    => $cron_hour,
    minute  => $cron_minute,
  }
}


# Use it like this to run puppet

cron::interval{'early_puppet_run':
  start_hour => 5,
  length     => 120,
  comment    => 'run puppet early in the morning form 5 to 7',
  command    => '/opt/puppetlabs/bin/puppet agent --test --color false'
}

Regards
Andreas
