Add Syslog Appender for JOC Cockpit System Notifications

Current Situation

• JOC Cockpit offers System Notifications from the Monitor view. Notifications are created from errors and warnings that are added to JOC Cockpit log files.

Desired Behavior

• Errors and warnings that are added to log output of Controller and Agents are similarly made available for JOC Cockipt.
• The Controller's and Agents' Log4j configuration is added a Syslog Appender that forwards errors and warnings to the JOC Cockpit Log Management Service.
  • The Syslog Appender is made available from related log4j2.xml and log4j2.xml-example files for Controller and Agent.
  • A FailoverAppender is made available for use with a JOC Cockpit cluster.
  • The Syslog Appender by default is inactive.
• The Syslog Appender configuration is added a number of properties to identify the source of logging.

Delimitation

• Users can forward log output of JS7 products (Controller, Agent, JOC Cockpit) to their own Syslog Service, for example to collect log output in a central Log Management tool. The related Log4j configuration is added by users. Use of an individual Syslog Server is independent form use of a Syslog Appender to feed JOC Cockpit System Notifications.
