I’m excited to share the news about an open-source utility I’ve been working on lately: JmFrX, a tool for capturing JMX data with JDK Flight Recorder. When using JMX (Java Management Extensions), The Java platform’s standard for monitoring and managing applications, JmFrX allows you to periodically record the attributes from any JMX MBean into JDK Flight Recorder (JFR) files, which you then can analyse using JDK Mission Control (JMC).
