Is there any way to profile Puppet recipes? For example, here's a node
(hostname changed to protect the innocent) in our nodes.pp:
node host002 {
include puppet_client_base
include subversion::server # sets up the system to be a subversion
server
include motd # controls /etc/motd from a template
include ntp # handles ntp client config
include user::root # ensures root user has correct uid, pw,
etc.
}
class puppet_client_base inherits base {
include common::puppet_client
}
class base {
include common::passwd # validates perms and ownership of
/etc/passwd, group, etc.
include dns::resolv_conf # creates /etc/resolv.conf
include ssh # controls /etc/ssh/ssh_config from template
include mcollective # installs mcollective and activemq client
config
}
That's not a huge amount IMHO but it takes around 34 seconds on a system
that is otherwise doing nothing. I'm assuming that some package checks are
what is taking the longest but I can't really tell, even from debug output.
It would be nice if I could run something like "puppet agent -t --profile"
and get output that reports how long classes take to evaluate/apply
(perhaps with even deeper breakdowns depending on what is done in each
class).
I tried the following but couldn't figure out how to get the current
timestamp in puppet:
/tmp # cat test.pp
class test {
notice("entering class $name")
package { "vim-common": ensure => present }
include foo
notice("leaving class $name")
}
class foo {
notice("entering class $name")
file { "/tmp/foo": ensure => present }
notice("leaving class $name")
}
include test
/tmp # puppet apply test.pp
notice: Scope(Class[Test]): entering class test
notice: Scope(Class[Foo]): entering class foo
notice: Scope(Class[Foo]): leaving class foo
notice: Scope(Class[Test]): leaving class test
notice: /Stage[main]/Foo/File[/tmp/foo]/ensure: created
notice: Finished catalog run in 0.67 seconds
/tmp #
Is any kind of profiling currently available, feasible, or even on the
roadmap?
Thanks,
Justin
