JMX metrics give solid insights into the workings of your application. Integrating them with Levitate (our time series data warehosue) required us to jump some hoops with vmagent.

The core functionality of the Java Instrumentation API lies in its ability to modify the bytecode of classes being executed by the virtual machine. This capability allows for a range of monitoring tasks to be carried out, such as event recording and data gathering, which can provide valuable insights into an application's performance and behavior.

Consider the scenario – You are an SRE (Site Reliability Engineer) joining a team to take charge of their Java applications. It has been reported that a Java application is very flaky in terms of memory issues.

However, logging is useful only if it provides the required information from the log messages without adversely impacting the system’s performance. Traditionally, implementing logging that satisfies these criteria in Java applications was a tedious process.
