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 its 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. You must not also declare the logrotate class if using this defined type as you will encounter a Puppet error if you attempt to do so.

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(s) to the log file(s) to be rotated.  May be a
                  String or an Array of Strings.
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'.
dateyesterday   - A Boolean specifying whether to use yesterday's date instead
                  of today's date to create the `dateext` extension (optional).
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).

                  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

maillast        - A Boolean that when used with `mail` has logrotate email the

                  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.

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,
    rotate       => 10,
    rotate_every => 'week',
    ifempty      => true,
  }
}

Additional startup arguments

With parameter logrotate_args you can specify additional startup arguments for logrotate. Configuration file is always added as the last argument for logrotate.

This example tells logrotate to use an alternate state file and which command to use when mailing logs.

class { '::logrotate':
  ensure         => 'latest',
  logrotate_args => ['-s /var/lib/logrotate/logrotate.status', '-m /usr/local/bin/mailer']
}

Cron output

By default, the cron output is discarded if there is no error output. To enable this output, when you (for example) enable the verbose startup argument, enable the cron_always_output boolean on the logrotate class:

class { '::logrotate':
  ensure              => 'latest',
  cron_always_output  => true,
  config              => {
    ...
  }
}

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 { 'servicelogs':
  path         => ['/var/log/this-service.log', '/var/log/that-app.log'],
  rotate       => 5,
  rotate_every => 'day',
  postrotate   => '/usr/bin/kill -HUP `cat /run/syslogd.pid`',
}

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