optimization - Templating MySQL's my.cnf for setup in Puppet -

i have been tasked templating mysql's my.cnf in attempt standardize configuration amongst slave databases using puppet. right now, i'm targeting innodb settings. there configuration options can safely calculated against hardware specifications such memory, disk , procs?

you need facter.

puppet:/etc/puppet/modules/master/lib/facter$ cat disks.rb #!/usr/bin/ruby #require 'facter'  mount = `/bin/mount` disks=array.new  mount.split("\n").each_with_index { | disk,i |   unless disk.scan(/ext3|simfs|reiserfs|xfs/).empty?     d=disk.split[2]     disks.push d     disks.push ','  end }  facter.add('disks')  setcode    disks  end  end  

` , in puppet.pp use facts $disks

#add disk check zabbix exec { "create_host":     command => "/bin/echo $fqdn $ipaddress $disks | do_work",     require => file["/root/ticket"],     subscribe => file["/root/ticket"],     refreshonly => true, }
