Now that you’ve deployed your code, it’s time to monitor it, collect data, and analyze your metrics. Without application performance monitoring in place, you can’t accurately determine how well things are going. Is the app performant? Are people using your app? Do the pages load quickly? Are your users experiencing any errors?
