Error Tracking

The mParticle SDK lets you track “errors” and “exceptions”. These two terms have slightly different meanings:

  • An error is a designed error state in your app, such as a failed login.
  • An exception is an error thrown by the app or site.

As with other events, extra attributes can be passed via the Event Info object.

Log Errors

mParticle.logError('Login failed');

Automatic Exception Tracking

The SDK can be configured to intercept calls to the JavaScript error console in Chrome and Firefox, and pass information on to mParticle:

(function () {
  var log = console.log;
  console.log = function () {
    var args =;
