I know it's an old post but it can be useful anyway as others solution are not compatible with older browsers.

You can redefine the behavior of each function of the console (and for all browsers) like this:

// 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
        }
    };
}(window.console));

//Then redefine the old console
window.console = console;
