Let’s say your colleagues are debating whether to employ synthetic or real user monitoring. How is real user monitoring different than synthetic checks or otherwise known as synthetic performance monitoring?


Options are :

  • Synthetic performance monitoring analyzes the engagement of software and notes its performance in the real world scenario. Real user monitoring observes performance of the user, not a real user, in a simulated world.
