I have a B2B eCommerce website and we have some business transactions. For that, we have configured the business transactions in AppDynamics. Apart from that, we have a list of servers that we have configured in AppDynamics, to send us some sort of alert if there's something bad or the servers are in disguise or something.
First, we use it to handle the business transactions alerting, and then the servers alerting. And second, we use it to create the dashboard so that we can get real-time updates on how the system is performing at around runtime.
