Mobile applications are more and more becoming part of a company’s online services. This leads to the question whether we need to monitor like other parts of our IT infrastructure. As they are part of our shipped application services we need to ensure they are working properly. However, not every application must be monitored the same way. Additionally monitoring always comes at a certain cost. We need people to take care of the monitoring, we have to prepare our applications to be ready for monitoring and we potentially also have to buy or at least integrate new monitoring tools. So is it worth the investment?
