Monitor Your Application

When it comes to an application's performance, you will quickly need to know what your application does and get the metrics of performance. In this chapter, we will identify a few ways to get insights on applications.

Thus, in this chapter, we will learn how to monitor our application's behavior in order to be able to compare it with the response times and execution times we observe. This will therefore show you the following:

• How to add monitoring or profiling to an existing application
• How to read important figures corresponding to the monitoring of an application
• How to ensure that the application performance is monitored and that any unexpected changes are visible
