Puppet Class: mediawiki::syslog

Defined in:
modules/mediawiki/manifests/syslog.pp

Overview

Class: mediawiki::syslog

Hosts running MediaWiki configure Apache and HHVM to log to syslog. This Puppet class configures rsyslog to handle log messages from Apache by writing them to disk and forwarding them to the MediaWiki log aggregator via UDP. It also sets up log rotation for the local log files.

Parameters:

  • forward_syslog (Optional[String]) (defaults to: undef)
  • log_aggregator (Optional[String]) (defaults to: undef)
