The event is emitted when the process recieves a message object from another cluster process by .send().

The callback will be passed the message object.

Message Object Structure:

{
        from: <worker ID>/<string "master">
        msg: <message data>
}

Example Code:

var cluster = require('cluster-mode');
cluster.on('message', function (data) {
        console.log('message was sent from', data.from);
        console.log('sent message is', data.msg);
});

sync event added

Emitted when worker map is synced.

The callback will be passed the worker map (Same map as .getWorkers() would return).

NOTE: If sync option is set to false in the configuration object for .start(), the event will NOT be emitted.

sync flag added to configuration object for .start()

Default Configurations

{
        max: <number of CPU available>,
