exec resource long runtime

[Royee Tager]

Hi, 

If I run the following command manually (time /usr/sbin/rhnreg_ks -v --serverUrl=http://spacewalk.example.com/XMLRPC --activationkey=1-aab07306b6f673c367ebecae2aa55f22 --force --nohardware --nopackages --novirtinfo --norhnsd -v), the runtime is 15 seconds. However, if the command is performed via the exe resource the runtime is ~48 seconds.

Why is the runtime via the exe resource longer?

Is it possible shorten the runtime?

class spacewalk::config inherits spacewalk {

  file { '/etc/yum/pluginconf.d/rhnplugin.conf':

    ensure   => present,

    source   => 'puppet:///modules/spacewalk/rhnplugin.conf',

    owner    => root,

    group    => root,

    mode     => '0644',

    before   => Exec['register-client'],

  }

  exec { 'register-client':

    command => "/usr/sbin/rhnreg_ks -v --serverUrl=http://${::spacewalk::spacewalk_server_fqdn}/XMLRPC --activationkey=${::spacewalk::activation_key} --force --nohardware --nopackages --novirtinfo --norhnsd -v",

    require => Class['spacewalk::install'],

    unless  => '/usr/sbin/spacewalk-channel -l',

  }

}

Thank you in advance,

The 48 seconds is the complete time the agent needs for the catalog.
Within the catalog you are running two commands:

spacewalk-channel -l and rhnreg.

Please add both execution times when comparing.

Please also keep in mind that puppet is doing more:

require => Class['spacewalk::install'],

There is another class which also gets executed.

The 48 second is not only the command execution time.
Its the whole catalog apply time.
Puppet always checks whether it has do do something prior doing changes.
e.g. check file md5sum, owner and group and permissions.

hth,

Martin

Hi Royee,

Try adding --evaltrace to your puppet run to see how long each resource is taking to apply.

Thanks,

Trevor
