Red Hat’s latest build of Cryostat 2.4, designed specifically for the Red Hat OpenShift Container Platform, brings a wealth of features and enhancements that cater to various monitoring needs for Java applications.

At its core, Cryostat 2.4 excels in comprehensive Java Flight Recorder (JFR) data management. Users can effortlessly start, stop, retrieve, archive, import, and export JFR data, all through an intuitive web console or an accessible HTTP API. This enhances the ease with which developers can handle JVM performance data. Moreover, Cryostat 2.4 provides flexibility in terms of data storage and analysis. Users can store and analyze JFR data directly on their Red Hat OpenShift or export it to external monitoring applications for a deeper dive into the data.
