config.yaml

options:
  logrotate-retention:
    type: int
    default: 30
    description: |
      The logrotate retention period in days. The charm will go through `ALL`
      logrotate entries in /etc/logrotate.d/ and set the `rotate` config to
      the appropriate value, depending on the rotation interval used.
      For example if rotation is monthy and retention is 180 days -> `rotate 6`
      or rotation is daily and retention is 90 days -> `rotate 90`
      or rotation is weekly and retention is 21 days -> `rotate 3`
      Weekly will round up the week count, for example if retention is set
      to 180 days -> `rotate 26` (26 weeks x 7 days = 182 days)
      Yearly will put rotate to 1 and increase it with 1 for each 360 days.
  logrotate-cronjob:
    type: boolean
    default: True
    description: |
      Enabled or disables the creation of a cronjob for the automatic updating
      of the logrotate files.
  logrotate-cronjob-frequency:
    type: string
    default: 'hourly'
    description: |
      If logrotate-cronjob is True, then this value is used to determine the
      location of the cronjob file.
      Valid options are 'hourly', 'daily', 'weekly', 'monthly'.
  update-cron-daily-schedule:
    type: string
    default: 'unset'
    description: |
      This value determines the time schedule with which the cron.daily job in
      /etc/crontab runs. This is done in order to control the execution time for
      the `/etc/cron.daily/logrotate` job.
      Valid options:
      'unset': No change to default cron.daily schedule.
      'set,HOUR:MINUTE': cron.daily schedule will be set to timestamp HOUR:MINUTE (24H) daily.
      'random,START_HOUR:START_MINUTE,END_HOUR:END_MINUTE': cron.daily schedule will be set
      to some random value between START_HOUR:START_MINUTE,END_HOUR:END_MINUTE (24H) daily.
      Note that all cron.daily jobs are affected by this config. They still run once a
      day but according to the time specified here.
  override:
    type: string
    default: '[]'
    description: |
      JSON-formatted string with override options for files in /etc/logrotate.d/
      This override takes precendence over all other options. Format is:
      [ {"path": "/etc/logrotate.d/rotatefile", "rotate": 5, "interval": "weekly", "size": "100M"}, {}, ... ]
      Mind the quotes for JSON properties/values!
      Valid options for rotate: any integer value
      Valid options for interval: 'daily', 'weekly', 'monthly', 'yearly'
      Valid options for size: any integer value with unit suffix, for example, '100', '100k', '100M', or '100G'.
      Note that the size and interval are mutually exclusive, and size takes the
      precedence.
