Logrotate module for Puppet

Disclaimer

This module is a fork of https://github.com/rodjek/puppet-logrotate merging some of the outstanding pull requests

I have also added the puppetlabs_spec_help functionality as used in Gareth Rushgrove's puppet-module-skeleton.

Description

A more Puppety way of managing logrotate configs. Where possible, as many of the configuration options have remained the same with a couple of notable exceptions:

  • Booleans are now used instead of the <something>/no<something> pattern. e.g. copy == copy => true, nocopy == copy => false.
  • create and it's three optional arguments have been split into seperate parameters documented below.
  • Instead of 'daily', 'weekly', 'monthly' or 'yearly', there is a rotate_every parameter (see documentation below).

logrotate::conf

You may, optionally, define logrotate defaults using this defined type. Parameters are the same as those for logrotate::rule. Using this type will automatically include a private class that will install and configure logrotate for you.

logrotate::rule

The only thing you'll need to deal with, this type configures a logrotate rule. Using this type will automatically include a private class that will install and configure logrotate for you.

namevar         - The String name of the rule.
path            - The path String to the logfile(s) to be rotated.
ensure          - The desired state of the logrotate rule as a String.  Valid
                  values are 'absent' and 'present' (default: 'present').
compress        - A Boolean value specifying whether the rotated logs should
                  be compressed (optional).
compresscmd     - The command String that should be executed to compress the
                  rotated logs (optional).
compressext     - The extention String to be appended to the rotated log files
                  after they have been compressed (optional).
compressoptions - A String of command line options to be passed to the
                  compression program specified in `compresscmd` (optional).
copy            - A Boolean specifying whether logrotate should just take a
                  copy of the log file and not touch the original (optional).
copytruncate    - A Boolean specifying whether logrotate should truncate the
                  original log file after taking a copy (optional).
create          - A Boolean specifying whether logrotate should create a new
                  log file immediately after rotation (optional).
create_mode     - An octal mode String logrotate should apply to the newly
                  created log file if create => true (optional).
create_owner    - A username String that logrotate should set the owner of the
                  newly created log file to if create => true (optional).
create_group    - A String group name that logrotate should apply to the newly
                  created log file if create => true (optional).
dateext         - A Boolean specifying whether rotated log files should be
                  archived by adding a date extension rather just a number
                  (optional).
dateformat      - The format String to be used for `dateext` (optional).
                  Valid specifiers are '%Y', '%m', '%d' and '%s'.
delaycompress   - A Boolean specifying whether compression of the rotated
                  log file should be delayed until the next logrotate run
                  (optional).
extension       - Log files with this extension String are allowed to keep it
                  after rotation (optional).
ifempty         - A Boolean specifying whether the log file should be rotated
                  even if it is empty (optional).
mail            - The email address String that logs that are about to be
                  rotated out of existence are emailed to (optional).
mailfirst       - A Boolean that when used with `mail` has logrotate email the
                  just rotated file rather than the about to expire file
                  (optional).
maillast        - A Boolean that when used with `mail` has logrotate email the

                  but not before the scheduled rotation time (optional).
                  The default units are bytes, append k, M or G for kilobytes,
                  megabytes and gigabytes respectively.
maxsize         - The String maximum size a log file may be to be rotated;
                  When maxsize is used, both the size and timestamp of a log
                  file are considered for rotation.
                  The default units are bytes, append k, M or G for kilobytes,
                  megabytes and gigabytes respectively.

Further details about these options can be found by reading man 8 logrotate.

logrotate

You may, optionally, declare the main ::logrotate class to adjust some of the defaults that are used when installing the logrotate package and creating the main /etc/logrotate.conf configuration file.

This example will ensure that the logrotate package is latest and that the dateext and compress options are added to the defaults for a node.

class { '::logrotate':
  ensure => 'latest',
  config => {
    dateext  => true,
    compress => true,
  }
}

Examples

logrotate::conf { '/etc/logrotate.conf':
  rotate       => 10,
  rotate_every => 'week',
  ifempty      => true,
  dateext      => true,
}

logrotate::rule { 'messages':
  path         => '/var/log/messages',
  rotate       => 5,
  rotate_every => 'week',
  postrotate   => '/usr/bin/killall -HUP syslogd',
}

logrotate::rule { 'apache':
  path          => '/var/log/httpd/*.log',
  rotate        => 5,
  mail          => 'test@example.com',
  size          => '100k',
  sharedscripts => true,
  postrotate    => '/etc/init.d/httpd restart',
}
