Usage of iRules LX Log Publisher

The tmsh help (tmsh help ilx plugin) says:

log-publisher Specifies the log destination for messages generated by the ILXLogger nodejs object in an extension. See sys log-config publisher.

So, it is essentially an HSL just like iRule's HSL::send (see Manual Chapter: Configuring Remote High-Speed Logging for how you create a log publisher).

You can find some hints on the ILXLogger class in the code itself: e.g.,

/var/ilx/workspaces///extensions//node_modules/f5-nodejs/lib/ilx_logger.js

A sample code as below:

var f5 = require('f5-nodejs');
var plugin = new f5.ILXPlugin();
var logger = new f5.ILXLogger();

plugin.on('connect', function(flow) {
  logger.send('Hola Mundo');
});

// Start listening for new flows.
var options = new f5.ILXPluginOptions(); // options are optional
options.handleClientData = false;     // default true
options.handleServerData = false;     // default true
options.handleClientRequest = false;  // default true
options.handleServerResponse = false;    // default true
plugin.start(options);

Once you created a log publisher, you can register it to the ILX plugin/extension from the GUI field Log Publisher (Local Traffic > iRules:LX Plugins > ).

Unfortunately, the API Reference does not show anything on the ILXLogger yet. I will check if I can do something about it.
