When your application has gone live, you will probably want some way of monitoring it. For example, it would be very helpful if you were able to see how many users are visiting your site, where they are visiting from, or if it is even still running at all. This article will go through some free tools that can help you accomplish just that.
Google Analytics can help check how many visitors you get, which location (both geographic and links) they are coming from, and what time people tend tovisit. To get started, create an account here: https://analytics.google.com/analytics/web/
It can take 24 hours for it to start working. Please note that AdBlocker addons can prevent Google Analytics from tracking you (this also means other users using adblocker may not be tracked as well). If you are having issues with this, I would recommend download the Google Tag Assistant addon (or other Google Analytics addons) since it can help provide you more information on any errors your website may be having with the script.
A very simple free service that checks your website every once in a while to see if it is down. You can sign up at their website here: https://uptimerobot.com/ and follow their instructions to send you email notifications whenever a website is detected to be down.
