I really like the concept of Happy Apps. It's very easy to use and you can monitor your servers. I like that you can create different dashboards and you can also monitor multiple servers. I don't like that you have to pay monthly for the premium plan, even if you don't use it. I also don't like that you can't easily log in to the dashboard from a computer or mobile device. I would say that if you are looking to monitor your servers you should try it. We needed to monitor our servers to make sure they were up and running and to also make sure we had enough resources for our customers.
