Salt Logrotate Formula

Logrotate is designed to ease administration of systems that generate large numbers of log files. It allows automatic rotation, compression, removal, and mailing of log files. Each log file may be handled daily, weekly, monthly, or when it grows too large.

Example pillar

Configuration for syslog from Ubuntu 14.04 (trusty):

logrotate:
  server:
    enabled: true
    job:
      rsyslog:
        - files:
          - /var/log/mail.info
          - /var/log/mail.warn
          - /var/log/mail.err
          - /var/log/mail.log
          - /var/log/daemon.log
          - /var/log/kern.log
          - /var/log/auth.log
          - /var/log/user.log
          - /var/log/lpr.log
          - /var/log/cron.log
          - /var/log/debug
          - /var/log/messages
        options:
          - rotate: 4
          - weekly
          - missingok
          - notifempty
          - compress
          - delaycompress
          - sharedscripts
          - postrotate: "reload rsyslog >/dev/null 2>&1 || true"
      - files:
          - /var/log/syslog
        options:
          - rotate: 7
          - daily
          - missingok
          - notifempty
          - delaycompress
          - compress
          - postrotate: "reload rsyslog >/dev/null 2>&1 || true"

Change parameters in main logrotate.conf file:

logrotate:
  server:
    enabled: true
    global_conf:
      compress: true
      rotate: daily
      keep_rotate: 6
      dateext: true

Cross-formula relationship

It's possible to use support meta to define logrotate rules from within other formula.

Example meta/logrotate.yml for horizon formula:

job:
  horizon:
    - files:
        - /var/log/horizon/*.log
      options:
        - compress
        - delaycompress
        - missingok
        - notifempty
        - rotate: 10
        - daily
        - minsize: 20M
        - maxsize: 500M
        - postrotate: "if /etc/init.d/apache2 status > /dev/null; then /etc/init.d/apache2 reload > /dev/null; fi"
