Just enhancing the previous answer of @Ludovic to make his answer also support nodejs:

// define a new console
var console=(function(oldCons){
    return {
        log: function(text){
            oldCons.log(text);
            // Your code
        },
        info: function (text) {
            oldCons.info(text);
            // Your code
        },
        warn: function (text) {
            oldCons.warn(text);
            // Your code
        },
        error: function (text) {
            oldCons.error(text);
            // Your code
        }
    };
}(global.console !== undefined ? global.console : window.console));
