  2. Can we access Java Mission Control using Code? (like I can see the visualisation of my problem but I want to fetch it into my IDE using code), is it possible?

Is JMC part of JDK?

The Java Mission Control (JMC) is a new JDK profiling and diagnostics tools platform for HotSpot JVM. It is a tool suite for basic monitoring, managing, and production time profiling and diagnostics with high performance.

How do I run a JMC file in Linux?

If the JAVA_HOME/bin directory is in the PATH environment variable, you can start the JMC client by entering jmc at the command-line prompt (shell). Otherwise, you have to specify the full path to the JMC executable: JAVA_HOME\bin\jmc.exe (Windows) JAVA_HOME/bin/jmc (Linux, OS X)

What is JMC EXE?

Description. Java Mission Control is a tool for production time profiling and diagnostics for the HotSpot JVM. The two main features of Java Mission Control are the Management Console and Java Flight Recorder, but several more features are offered as plug-ins, which can be downloaded from the tool.

If you are using Oracle JDK 9+ or OpenJDK 11+, you can access the data in a JFR file using the Flight Recorder API.

For example, to print all the events:

import jdk.jfr.consumer.*;

try (RecordingFile r = new RecordingFile(Path.of("recording.jfr"))) {
 while (r.hasMoreEvents()) {
   System.out.println(r.readEvent());
 }
}

For more information about the API: https://docs.oracle.com/en/java/javase/11/docs/api/jdk.jfr/jdk/jfr/consumer/package-summary.html
