List configuration options for sources and destinations

You can use the syslog-ng-cfg-db.py utility to list the available options of configuration objects. For example, you can list all the options that can be set in the file source, and so on. For details, see "Listing configuration options" in the Administration Guide.

Visualize the running configuration

Starting with syslog-ng OSE 3.25, you convert the configuration of a running syslog-ng OSE instance into DOT format, and visualize it or convert it into PNG or PDF format. For details, see "Visualize the configuration" in the Administration Guide.

Enhancements

• The default-network-drivers() source now supports the max-connections() option.

  NOTE:

  Starting with 3.0.26, syslog-ng OSE assigns a persist name to Python sources and destinations. The persist name is generated from the class name. If you want to use the same Python class multiple times in your syslog-ng OSE configuration, add a unique persist-name() to each source or destination, otherwise syslog-ng OSE will not start. For example:

  log {
      source { python(class(PyNetworkSource) options("port" "8080") persist-name("<unique-string>); };
      source { python(class(PyNetworkSource) options("port" "8081")); };
    };

  Alternatively, you can include the following line in the Python package: @staticmethod generate_persist_name. For example:

  from syslogng import LogSource
    class PyNetworSource(LogSource):
      @staticmethod
      def generate_persist_name(options):
          return options["port"]
      def run(self):
          pass
      def request_exit(self):
          pass
