Starting with syslog-ng OSE 3.25, 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.

The syslog-ng-cfg-db.py utility has the following options:

• The following command lists the contexts that the utility supports.

  syslog-ng-cfg-db.py

  NOTE: Currently, sources and destinations are supported.

• The following command lists the available drivers of a context:

  syslog-ng-cfg-db.py -c <source|destination>

• The following command lists the available options of a specific driver and specifies the context and the driver:

  syslog-ng-cfg-db.py -c <source|destination> -d <driver>

  For example, to list the options of the kafka-c() destination driver:

  syslog-ng-cfg-db.py -c destination -d kafka-c

  The output includes the available options of the driver in alphabetical order, and the type of the option. For example:

  destination kafka-c(
      bootstrap-servers/kafka-bootstrap-servers(<string>)
      client-lib-dir(<string>)
      config/option()
      config/option(<string> <arrow> <string-or-number>)
      config/option(<string> <string-or-number>)
      flush-timeout-on-reload(<number>)
      flush-timeout-on-shutdown(<number>)
      frac-digits(<number>)
      key(<string>)
      local-time-zone/time-zone(<string>)
      log-fifo-size(<number>)
      message/template(<string>)
      on-error(<string>)
      persist-name(<string>)
      poll-timeout(<number>)
      properties-file(<path>)
      send-time-zone(<string>)
      sync-send(<yesno>)
      throttle(<number>)
      time-zone(<string>)
      topic(<string>)
      ts-format(<string>)
      workers(<number>)
      config/option(
          <string>(<string-or-number>)
      )
      key(
          <identifier>(<string>)
      )
      message/template(
          <identifier>(<string>)
      )
  )

  NOTE: The script caches the list of the options, so if you want to rebuild the database, you have to use the -r option.
