monitoring interface. After the installation is complete and set up as the developer version of TC Server, then deploy the application on the TC server. I look at the Insight interface, which is a good way to monitor classes and methods, and see how much time is spent to complete this method. I can also see the input parameter values, as well as the return values. Since my application is spring-based, spring insight can provide very useful data. The TC server plug-in configuration is similar to
