In order to get an idea of how successful your app is, you need to keep a close eye on the request rate. Nearly every other metric you will monitor on your app will be affected greatly by sudden increases and decreases in traffic.
The higher the amount of traffic your app gets, the easier you will find it to make some money on the program. Consulting with app developers is a great way to figure out how to handle sudden surges in traffic without having your app crash as a result.
The only way to find out what your app can handle before launching it is by load testing it. With the results of this load test, you can figure out where any vulnerabilities are. By fixing these problems before launch, you can keep your app reliable with ease.
Ignoring the important metrics mentioned above is a recipe for disaster. With the help of the right software and knowledgeable app developers, you can keep your app running strong for years to come.
