You can add following code to notify jQuery Ajax errors to Atatus.
function processJQueryAjaxError(event, jqXHR, ajaxSettings, thrownError) {
var message = 'AJAX Error: ' +
(jqXHR.statusText || 'unknown') +' '+
(ajaxSettings.type || 'unknown');
atatus.notify(thrownError || event.type, {
status: jqXHR.status,
statusText: jqXHR.statusText,
type: ajaxSettings.type,
url: ajaxSettings.url,
ajaxErrorMessage: message,
contentType: ajaxSettings.contentType,
activeTarget: event.target && event.target.activeElement ? event.target.activeElement.outerHTML : undefined
});
}
$(document).ajaxError(processJQueryAjaxError);
