Constructor Details

- (Syslog) initialize(*args)

Open the syslog library, if it is already open, we reopen it using the new argument list. The argument list is passed on to the Syslog library so please check that, and man syslog for detailed information.

There are 3 parameters:

  • ident: The identification used in the log file, defaults to $0
  • options: defaults to Syslog::LOG_PID | Syslog::LOG_CONS
  • facility: defaults to Syslog::LOG_USER

  ::Syslog.inspect
end

- (Object) log(tag, *messages)

Just sends all messages received to ::Syslog We simply return if the log was closed for some reason, this behavior was copied from Informer. We do not handle levels here. This will be done by the syslog daemon based on it's configuration.
