Information in this document applies to any platform.
Oracle recommends setting up Java Mission Control with Java Flight Recorder - JFR to monitor the systems on an ongoing basis while having the lowest possible impact on the running system. This is a best practice to supplement the OUD standard data collection of RDA data collection and logs. It is a constant monitoring of the java layer over a rolling period of time, at a lower level than that captured in logs or from jstack snapshots collected by RDA. Since it will cover a period of time (an hour or more) and at greater depth, it is much more likely to capture the java activity leading up to an issue which, in turn, will increase the possibility of identifying root cause and solution.
